    Default New to java, over 100 errors please help

    Hi, I'm new to java and I just started getting into what I feel is more complicated stuff and I spent all morning making a cheesy fighting game involving people I know (so don't mind the cheese), but when I try to compile I get 100 errors, hopefully due to a few small mistakes shifting the entire code. I'm sorry for the length and amount of probably unnecessary code, but I'm new.
    Also, Don't mind anything involving the class GameHelper or .getUserInput, these are in a separate class file that I got from my book's website to enable user input.
    Thanks for your help
    What I try to do in this code:
    • Have each person choose which character by inputting a number from 0 to 3, and assign a name and an array of attack styles
    • Have each player choose a type of attack (0=weak, 1=strong, 2=guard, 3=heal) and have damage done scaled to that
    • Tell the players what attack was used and for how much damage/heal for how much
    • When a character is at 0 or lower health, end the game and say the winner


    If you do take the time to help, thank you, and please try to explain in a way that a newbie can understand.

    class Character {
	String[] AttackStyle;
	int Health=100;
	String name;
	public void getAttackStyle(String charNum) {
		int Selection=Integer.parseInt(charNum);
		if (Selection==0) {
			name="Garrett";
			AttackStyle={"throws a game disc at", "punches", "kicks", "throws a grand piano at", "smashes a coke bottle over the head of", "bores to death", "guards against", "sleeps and doesn't fight"};
		} else if (Selection==1) {
			name="Kathy";
			AttackStyle={"throws an apple at", "punches", "knees", "takes a paint brush and stabs", "takes a ball of ribbon and strangles", "radiates cuteness, setting on fire", "guards against", "naps and doesn't fight"};
		} else if (Selection==2) {
			name="Kevin";
			AttackStyle={"throws a chess piece at", "closes a chess tutorial book on", "swings homework at", "throws a grand piano at", "lights college apps on fire, setting fire to", "unleashes k-pop star powers on", "guards against", "naps and doesn't fight"};
		} else {
			name="Cheyenne";
			AttackStyle={"licks, transferring tapeworm to", "stratches", "whimpers loudly at", "slams her massive body into", "snarls and bites", "falls down the stairs onto", "guards against", "sleeps and doesn't fight"};

    What errors are you getting? Can you provide the stack trace? And please leave references to line numbers (if it says there is an exception on line 5, please tell us what line 5 is).
    NOTE TO NEW PEOPLE LOOKING FOR HELP ON FORUM:

    When asking for help, please follow these guidelines to receive better and more prompt help:
    1. Put your code in Java Tags. To do this, put [highlight=java] before your code and [/highlight] after your code.
    2. Give full details of errors and provide us with as much information about the situation as possible.
    3. Give us an example of what the output should look like when done correctly.

    Whenever I see a statement like this, it concerns me, not so much about the errors, but rather that the poster is going about coding wrong. If you're not using an IDE, you must be sure to compile your code very often, perhaps after each line or 3 of code added, and (here's the important part) make sure to fix any and all compiler errors before adding any more code. If you don't do this, you risk adding good code to bad, kind of like trying to build a bridge with a bad foundation -- it's guaranteed to fail. So I hope you fix your current errors, but more importantly, I strongly urge you to change your coding habits; you won't be sorry you did.

    Also when you get a bit more familiar with Java, start using an IDE like NetBeans or Eclipse since these guys will point out your compiler errors almost immediately as you are typing in your code, and this will help alert you to make changes before adding more code.

    Best of luck!

    I'll be blunter than Fubarable: start again.

    This isn't meant to be discouraging - quite the opposite. I genuinely believe you'll make faster progress by addressing each compiler message as it occurs. As aussie says: post the message(s) here and say what line(s) are being referred to. Much of the code is repetition of the same logic (multiple characters, multiple health levels etc) so get one to compile and the rest will (very likely) follow. As far as starting again is concerned we know how it feels because we've all been there.

    -----

    A couple of other things which are intended, like frequent compiles, to become unthinking, effortless, habit:

    * Use standard Java coding conventions. Variables begin with a lower case letter and class with an upper case one. Variables should be descriptive of the thing they represent. Imagine reading your code as a stranger might or as you might in 6 months: avoid nondescriptive variables like d2.

    * Compile every few lines. And listen to the compiler. But also test (by running the application) each time you finish a method. Ensure that the method does just what you expect (and consider documenting what that is in the code!)
