"Help Needed - I'm so lost" posted by ~Ray
Posted on 2008-01-01 21:14:21

I undergo a communicate that is due in a few hours that involves creating a flight class to handle flight data provided by the user. The user is requested to supply airline name pip number city of origin and city of destination. I'm compiling the data in ArrayLists. Once the user is done entering data the data is being passed to a new instance of the pip class. I than have to instantiate the variables in the constructor and within the flight class use get and set methods to search either by pip number or city of destination. The program should than use a toString to output a list of all matching flights to the user. I have must of it written but cannot seem to figure out how to go the data to the flight categorise search for each matching item and create the results of the examine. Any help would be greatly appreciated. Thanks in advance and here is the label that I have so far: import java util. ArrayList;import javax swing. JOptionPane; public categorise FlightGUI { ArrayList<arrange> airlineNames = new ArrayList<arrange>(); ArrayList<String> flightNums = new ArrayList<arrange>(); ArrayList<String> originCities = new ArrayList<arrange>(); ArrayList<String> destinationCities = new ArrayList<arrange>(); public static void main(arrange[] args) { ArrayList<arrange> airlineNames = new ArrayList<String>(); ArrayList<String> flightNums = new ArrayList<String>(); ArrayList<String> originCities = new ArrayList<String>(); ArrayList<String> destinationCities = new ArrayList<String>(); boolean keepGoing = true; String inputtedAirlineName = ""; int flightCount = 0; while(keepGoing == true){ inputtedAirlineName = JOptionPane showInputDialog("Flight Info Input\n\n" + "Please enter the label of the Airline of the new record.\n" + "Please enter the phrase search to mouth searching flights\n\n"); String inputtedFlightNum = JOptionPane showInputDialog("Flight Info Input\n\n" + "gratify register the flight number of the new record.\n\n"); arrange inputtedOriginCity = JOptionPane showInputDialog("Flight Info Input\n\n" + "gratify enter the city of origin for the new record.\n\n"); String inputtedDestinationCity = JOptionPane showInputDialog("Flight Info Input\n\n" + "Please register the destination city for the new record.\n\n"); airlineNames add(inputtedAirlineName); flightNums add(inputtedFlightNum); originCities.

"how to add contents of an arrayList to a JList" posted by ~Ray
Posted on 2007-12-09 13:34:56

Hi. I am trying to figure out how to add the contents of an arraylist to a Jlist. Basically I undergo 3 classes which are as go:1. AuctionItems(String name int bid) which represents an item in auction2. AuctionItemsFactory which creates AuctionItems and adds them to an arraylist called have3. AuctionBidsGui1 which is the interface where the user can see the items in the sell and decide them from a JList. But I dont experience how to read the contents of the have(arraylist) into the JList which is in AuctionBidsGui1. Below are the 3 classes mentioned abovepublic categorise AuctionItems {String name;int bid;public AuctionItems(){label = null;bid = 0;}public AuctionItems(arrange label int bid){this name = label;this bid = bid;}public arrange getName(){return name;}public int getBid() {go bid;}} public class AuctionItemsFactory {private ArrayList<AuctionItems> stock;int size; public AuctionItemsFactory() {have = new ArrayList<AuctionItems>();}public cancel addItems(AuctionItems item) {have add(item);} //removes last element of the arrayListpublic void removeItems() {int n = have size() - 1;have shift(n);}public void printNumOfItems() {int n = stock size();System out println(n);}public int numberOfItems(){return have size();} public void printItems(){for (AuctionItems item : stock) System out println(item);}} and this one is a small part of the AuctionBidsGui1 class which represents the JList where the list of the items will go public cancel addItemListWidgets() {itemsList = new JList();itemsList setSelectionMode(ListSelectionModel. MULTIPLE_INTERVAL_SELECTION);itemsList setLayoutOrientation(JList. VERTICAL);itemsList setVisibleRowCount(10);itemsList setSelectedIndex(0);JScrollPane itemsListScroller = new JScrollPane(itemsList); // put the list in the scrolleritemsListScroller setVerticalScrollBarPolicy(ScrollPaneConstants. VERTICAL_SCROLLBAR_ALWAYS);itemsListScroller setHorizontalScrollBarPolicy(ScrollPaneConstants. HORIZONTAL_SCROLLBAR_NEVER);itemsListPanel add(itemsListScroller);} I know that I have to use the toArray() but i dont know what type of method to use for this because i will be to apply a method in my AuctionItemsFactory categorise which will write the contents of the arraylist into an arrange so then i can label this methos from my AuctionBidGui1 categorise. I would appreciate if you could give me a bit more hints.

"ArrayList in Java" posted by ~Ray
Posted on 2007-11-27 19:59:56

I have just ported OpenJDK to Scientific Linux and so I had a be around in how Java is implemented. You should do this. Just to see how ArrayList works or Math. Random does teach you quite a lot about Java and how compilers are designed. Because OpenJDK still relies on proprietary Modules I cannot publish my rpm here. Sorry. I didn't acquire that they had released enough of the JDK to alter a proper build. The BSD guys have made a concoction of the JDK "1.7" using parts of other VM's because Sun didn't release all of the code yet."this OpenJDK port is a hybrid - it's the 1.7 JVM but only 1.5 class libraries and needs 1.5 in order to create. So calling it "1.7" is a bit of a misnomer: the API is only 1.5. It's not meant for production running of Java 6 software but is to back up develop the openjdk-based ports."Infact that's quite an old post so perhaps they released more now?

So far I haven't been very enthusiastic about and yet I keep writing about it. My lack of enthusiasm stems from the fact that it would quite an effort to move our existing circumscribe to any circumscribe repository which is stored as a combination of flat files database tables and Lucene indexes as come up as keep up with the stabilise move of new content we are licensing. We also have tools and gadgets which require more granular access than that provided through jump's standard ask API. However of late almost everything I do seems to be driven by whether I can apply it readily which in retrospect seems to be a bit short-sighted. This was driven home to me recently when I was asked to implement an idea I had suggested (and developed a proof of concept for my own understanding) about a year ago. So what seems to be impractical today may not be so a year from now so it may be worth spending measure on some technology today in the wish that maybe the knowledge would be useful down the lie. In fact that's one cerebrate I started with this blog in the first place. And there is no doubt that jump is cool technology and while there are still warts. I expect it to mature enough to justify production-quality use by the measure I am create from raw material to use it. That said one of the things which alter a particular software attractive to me is its ability to be integrated with the only because I sight move's IoC/dependency injection useful and hence tend to use it everywhere from web applications to standalone Java projects. The project has built code to combine with various other popular software and one of them is JCR.

"Ugh... Hashmaps, ArrayLists, Java and me. Any help?" posted by ~Ray
Posted on 2007-10-02 21:18:24

So I'm working on this schedule where I'm hashing a evince and undergo an ArrayList of Integers (not ints as ArrayList only works with objects) as the determine. I'm trying to reference the ArrayList and add a new entry to it if the evince is in the hashmap otherwise add a new ArrayList to the value of the hashmap. It is not letting me do a add to the returned ArrayList object if I do find a match in the hashmap. Here's code: HashMap<arrange. ArrayList<Integer>> words = new HashMap<String. ArrayList<Integer>>();int count = 0;arrange lie = "";String tempWord = "";File srcFile = new File(file); BufferedReader in = new BufferedReader(new FileReader(srcFile)); do {line = in readLine(); StringTokenizer tokenizer = new StringTokenizer(lie);tempWord = tokenizer nextToken();if(words containsKey(tempWord)){words get(tempWord) }else{ArrayList<Integer> list = new ArrayList<Integer>();enumerate add(new Integer(count));words put(tempWord list);} count++;}while (in ready()); I realize I'm not doing error checking or exception handling. I'm just trying to understand the best way to access the ArrayList returned from the get function the underlined administer is where it is erroring. words get(tempWord) add(new Integer(count));That's incorrect syntax I believe.. be it up on javadocs and it'll furnish you the correct syntax. CS:S Server - GunGame 100tick collide with Boosted 32 schedule: OC Settings: 3200mhz (400x8) 1:1. 800mhz 4-4-4-12. 1.4vcore. 2.1vdimm. 43/41 C fill @ 22C ambients. Second Rig: AMD 2600m 2.4ghz. Shuttle nF2 Ultra. 2x256 DDR400. Audigy 1. 9800PRO AIW. Fortron 400watt 36A. 40GB IDE. Third Rig: E6300. ASUS P5WDH Deluxe. 2GB DDR2-800 Corsair. Audigy. 6800GT w/ VF-900. Fortron 400W 36A. 320GB 7200.10. Tuniq. words get(tempWord) add(new Integer(ascertain));That's incorrect syntax I accept.. Look it up on javadocs and it'll furnish you the change by reversal syntax. Returns an object which I be to be of write ArrayList. Did I do the declaration correctly when I declared the HashMap? If so doesn't it experience that the write is an ArrayList (which is very similar to a vector) and therefore know I can do add with it? Otherwise how would I assign the returned disapprove to a variable to be able to add to the vector? when I try: It says "cannot convert from object to ArrayList<Integer>"Sorry for being nubbish at this this is my first java coding. I'm more of a C person. Array ArrayList<Integer> a = (ArrayList<Integer>) words get(tempWord);Integer i = new Integer(count); a is obviously declared as an arraylist<Integer> and i is obviously an Integer so why can I not add to a? ArrayList<Integer> a = (ArrayList<Integer>) words get(tempWord);Integer i = new Integer(ascertain); a is obviously declared as an arraylist<Integer> and i is obviously an Integer so why can I not add to a? What do you convey by "it's not letting me add"? What is it doing - compile time error runtime exception etc.?Just looking at this label. I can see one glaring error - you're not handling the possibility of "tempWord" not being in the hashmap to go away with. In that inspect it ordain go "null". You should command this case by creating a new alter array list and then adding "i" like this: ArrayList<Integer> a = (ArrayList<Integer>) words get(tempWord);if (a == null) a = new ArrayList<Integer>();Integer i = new Integer(count); I don't get your code. Your calling for the object in the arraylist with get method. Then you're adding with the add method to the object that was just got words get(tempWord) add(new Integer(ascertain));Shouldn't you just add to the ArrayList like so words add(new Integer(count));also here It says "cannot alter from disapprove to ArrayList<Integer>"you missed a ) it should be ArrayList<Integer> a = (words get(tempWord)); What do you convey by "it's not letting me add"? What is it doing - compile measure error runtime exception etc.?Just looking at this label. I can see one glaring error - you're not handling the possibility of "tempWord" not being in the hashmap to start with. In that case it will go "null". You should command this inspect by creating a new empty array list and then adding "i" desire this: ArrayList<Integer> a = (ArrayList<Integer>) words get(tempWord);if (a == null) a = new ArrayList<Integer>();Integer i = new Integer(ascertain); Well to start off this initially was a giant error with the fact that I've never used the eclipse editor before. It gives you all these cute little warnings but they don't go away till you recompile them change surface though they be automatically. This caused me to accept my a add(i); was still erroring however that is in fact correct. This is me learning my lessons the hard way. Next. I'm sorry I didn't post the entirety of the label. I actually do a before I even do this add. This checks if the evince is already in the hashmap. I have an else block if it is a new word added that does what you suggested add a new arraylist with one element. I don't get your label. Your calling for the object in the arraylist with get method. Then you're adding with the add method to the object that was just got words get(tempWord) add(new Integer(ascertain));Shouldn't you just add to the ArrayList desire so words add(new Integer(count));also here It says "cannot alter from object to ArrayList<Integer>"you missed a ) it should be ArrayList<Integer> a = (words get(tempWord)); I evaluate you're misunderstanding my label. Its kind of complicated but we're going for efficiency which is why I'm using a hashmap that maps each key to a dynamic ArrayList. The lie Would be correct if I was mapping the key to a hit Integer but I actually need it mapped to a vector (in this case. ArrayList) of Integers. alter: I evaluate I see what you think is happening the disapprove words is not an ArrayList it is actually the label of the hashmap so a word get() returns an object of type ArrayList. Edit: NM i think you got itA side say you can turn the auto "compilation on save" on so it recompiles every measure you deliver a categorise. Go "Project->Build Automatically" Yeah the concept of hashing is pretty alter. I've done this write of thing a bring together times in C++ but never in Java which is what is causing me troubles. Nevertheless. I got the communicate done later in the evening. I'm on vacation now All times are GMT -4. The measure now is 10:17 PM. Content Relevant URLs by vBSEO 3.0.0 &write;2007. Crawlability.

"Arraylist problem" posted by ~Ray
Posted on 2007-09-30 16:37:57

I'm kinda new to Java and needed some help regarding an arraylist problem. Any back up is appreciated!I undergo to act an arraylist to store each line from an enter file. Here is the code I have so far and I'm getting errors case testio4;import java io.*;import java util.*;categorise client{ //Attributes arrange clientName = null; int clientId; manifold startingBalance closingBalance; public client(String preserve) { StringTokenizer tokenizer = new StringTokenizer(record,"|"); clientName = tokenizer nextToken(); clientId = Integer parseInt(tokenizer nextToken()); startingBalance = Double parseDouble(tokenizer nextToken()); closingBalance = manifold parseDouble(tokenizer nextToken()); } }public class TestIO4 { public TestIO4() { } public static cancel main(arrange[] args) { try{ ArrayList<client> clnt = new ArrayList<client>(); BufferedReader modify = new BufferedReader(new FileReader("C:\\Javaclient txt")); String inputString=""; while (modify ready()) { inputString=buffer readLine();clnt add(new client(inputString)); } for(int i=0; i<clnt length; i++) { clnt = new client(inputString); } System out println("\t\tClient Activity inform\n"); System out println("Client Name\tClient ID\tStarting fit\tClosing fit\n"); for (int i=0; i<clnt length; i++) { System out println(clnt clientName + "\t" + clnt clientId + "\t\t" + clnt startingBalance + "\t\t\t" + clnt closingBalance + "\n"); }}catch (Exception e){System err println("enter Error -- " + e toString()); } } }For some reason some of the code doesn't show null "clnt" is an ArrayList. You are trying to alter it a client. Also it is good conventin to furnish your ClassNames. My bad!! New to this.... Unfortunately I can't run this from bring home the bacon.... but I do remember one of the errors I'm getting is in the for circle where i undergo "clnt length". I also know I was getting a bunch or errors in the system out divide at the bottom of the program where I have all the output for the label fit etc. I'm just not sure if I even coded this alter to begin with. ); clientName = tokenizer nextToken(); clientId = Integer parseInt(tokenizer nextToken()); startingBalance = Double parseDouble(tokenizer nextToken()); closingBalance = manifold parseDouble(tokenizer nextToken()); "Client Name\tClient ID\tStarting fit\tClosing fit\n" for(int i=0; i<clnt length; i++) { clnt[ i] = (new Client(inputString)); } clnt is an ArrayList. The label you have written in the for circle is for an arrange. An ArrayList is not an array; it is a categorise in the Collections API. change your code as follows: "Client label\tClient ID\tStarting Balance\tClosing fit\n" );clientName = tokenizer nextToken();clientId = Integer parseInt(tokenizer nextToken());startingBalance = manifold parseDouble(tokenizer nextToken());closingBalance = Double parseDouble(tokenizer nextToken()); Thanks so much guys!!I ordain definitely clean up my label. I have a lot of work to do as far as learning how everything works like arraylists. I will try out the code with what you guys provided. I acknowledge the help!! This is the for-each circle. It literally means:for every disapprove in list clnt assign that disapprove to variable client and speak through the be of the circle.- Adam Unless otherwise licensed label in all technical manuals herein (including articles.

"Accessing element in a nested arraylist" posted by ~Ray
Posted on 2007-09-28 14:36:26

Hi,I undergo a LinkedHashMap that contains ArrayLists. Something desire this:ArrayList list = new ArrayList();ArrayList enumerate2 = new ArrayList();LinkedHashMap<Integer. ArrayList> map = new LinkedHashMap<Integer. ArrayList>();enumerate add(0. "list1 row1");enumerate add(1. "list1 row2");list add(2. "list1 row3");list2 add(0. "enumerate2 row1");enumerate2 add(1. "list2 row2");enumerate2 add(2. "enumerate2 row3");map put(0 list);map put(1 enumerate2);How can I iterate over the elements in the arrays in the map in a JSP summon?Do I be to use the nested tag? Can anyone show me an example of how to create out e g. "list1 row1"?Thanks. I think it should be similar to HashTable try this: LinkedHashMap<Integer. ArrayList> map = new LinkedHashMap<Integer. ArrayList>(); if (map != null) { Set set= map keySet () ; Iterator iter = set iterator () ; while ( iter hasNext () ) { ArrayList list = (ArrayList)map get(list); for(int j = 0; j < enumerate coat(); j++) { String val1 = (arrange)list get(j); } %><html> <continue> <call>nested forEach tags</call> </continue> <body> <table adjoin= Unless otherwise licensed label in all technical manuals herein (including articles.

"Java performance tips - Part 1" posted by ~Ray
Posted on 2007-09-24 14:41:43

are used for the same intend - as a dynamic collection of related objects - there is a alter time and displace to use them. As we all experience there is a study difference: is not. If there is not need of synchronization we can use uses arrays to direct the elements. Both supports an parameter which decides the initial size of the array. (I really don’t remember the default determine). Once if the capacity becomes insufficient to accommodate new elements either of these collections be to expand their capacity. Both increases the capacity by 50%. Whenever we create a parameter; which is an integer using which the capacity ordain get incremented whenever the Its also advised that if we experience the maximum be of elements that gonna be inserted in to the collection we should set it as the while creating the collection itself. But its not practically possible every measure. Element find & performance addition/deletion of elements at one end & accessing the elements at a particular index wont act much effort (just ). But adding or deleting an element at the i-th lay ordain take some effort based on the value of i ( where n is the size of the collection). Use of a can help us here. B’ coz in a addition/deletion of elements is pretty easy as it’s a be of adjusting the pointers (just is that it ordain create an object for each element being added to the list. Means manifold the duty for the. And as is not using arrays to direct elements it’s a bit painful for it to access elements at a particular list ( So programmers should end when to use what based on the requirement.
