It is right on the documentation located at the URL below. It gives you what to replace it with and an example. Just lookup readline() to construe all about it. apply!
So simple. I can't accept that I took a course on Java with the compilier I'm using I'm using and they never pointed that out. One semester and $300 later and I'm still ignorant to really use the online Java API. I've always disliked Georgia Southern. I probably should have just enrolled at </dic>. Thanks!
