Curly braces are sort of like parantheses for blocks of code. For instance, if you're designing a class, such as main, you want { after "public class main" which indicates main contains all of the following. Then a } to close off the class when you're all done. You'll also need them for blocks such as: When there is more than 1 line to do after an "IF" statement When there is more than 1 line to do after a "WHILE" statement etc. ...if there's still a problem, send me the code in question and I can almost definetly show you exactly where the problem(s) are.

I think my problem is I'm putting too many. You don't need them before and after declaring variables, right? When I move some brackets around, I get x's on the whole thing, and then they go away.

Well the following is a small class example just from what I currently have open at this very moment... It contains a field, a constructor, and a few short methods. ... basically everything you might see: package CardGame.Gameplay; import CardGame.Helpers.*; import CardGame.Cards.*; // Player's 'Hand' ... Just a list of cards. public class Hand { private List cards = new Empty(); public Hand() { } public void addCard(Card toAdd) { this.cards.add(toAdd); } public void removeCard(Card toRemove) { this.cards.removeCard(toRemove); } } p.s.: ALWAYS initialize your variables... Don't write int x; Write int x = 0; Otherwise you're opening the door for null pointer exceptions which are stressful and hard to track down. (Edited by Plastik at 4:05 pm on Sep. 23, 2005)

Aha! I had a char variable and I didn't set it to 0. I didn't know you had to set everything to 0, especially letters...and it said it wasn't initialized. It's fixed now, thanks.

You can set it to anything. As for the char... a char is actually a number, so setting it to 0 is alright. If it was a string, you'd want something like ... String x = ""; But it can be anything -- The problem is when anything looks at that variable before anything is put IN the variable...you get errors. Sometimes you might be looking at that variable without even realizing it, which just causes infinitely more confusion. So always remember to initialize it to SOMETHING.
