I thought I had it set up correctly but it prints out the prompt and then moves on, never allowing me to actually enter a name.

Replies Majo Posted at 8:58 pm on Oct. 31, 2008 I'm in Programming for Info Tech I. Sorry about the indents thing, I tried but every time I hit tab, my cursor jumped from within the text box to some other point on the screen so I gave up. As it turns out, taking out Line in scn.nextLine() did it. I have no idea why though. matto Posted at 12:54 am on Oct. 30, 2008 Can you post it with indents?  Hella hard to troubleshoot when it's like that. Also, if I were writing such a program, I'd implement a method called getInfo() or something within Player.java that input a Player object and prompted the user for and properly stored all of the information.  It'd shorten the amount of code significantly, and make troubleshooting much easier (if required at all).  Then your main would look something like Player player1 = new Player(); Player player2 = new Player(); player1.getInfo(); player2.getInfo(); System.out.println(player1); System.out.println(player2); If you put a toString() method in Player.java, then you can do the above.  System.out.println(player1) will print out the value of player1.toString() if such a method exists, also reducing the redundancy of your code. My bad if this is hella useless information.  I dunno what's wrong with your code because reading it is a bitch and it's difficult to find problems with it in its current, unindented form.  So yeah. You in AP CS?  It's teh shit I'm in that class right now ... Majo Posted at 7:36 pm on Oct. 29, 2008 println didn't work. I don't know what's wrong. We're working on arrays, too. They're kicking my ass as well. taraxgoesxboom Posted at 7:33 pm on Oct. 29, 2008 Quote: from Majo at 7:28 pm on Oct. 29, 2008 Quote: from taraxgoesxboom at 10:26 pm on Oct. 29, 2008 System.out.print("Please enter name of the second player: ");      It might be a syntax error, you forgot the ln on this line.    Are you using J creator? It wont compile it unless there are no syntax errors. No, I'm using jGRASP. I think I've tried println but I'll try it again. Sorry, other than that I don't really see what it's missing. Right now I'm working on arrays and their still kicking my butt, lol. Good luck.
