Compile Errors - Head First - GuessGame

[Temmu Smith]

I've created 3 .java files - 1 compiles, 2 give errors.
The folder that the .java files are in is part of the PATH statement, as is the location of the \BIN folder.
All 3 .java files are in the same directory.
Error messages posted after each .java file.

I have read the other 3 threads about this program - does not seem applicable - but, I'm just learning.
Advice greatly appreciated!

GameLauncher.java - does NOT compile:

public class GameLauncher
	{
	public static void main (String[] args)
		{
		GuessGame game = new GuessGame();
		game.startGame();
		}
	}

c:\some\path\here>javac GameLauncher.java
.\GuessGame.java:6: error: <identifier> expected

Player.java DOES compile

public class Player
	{
	int number = 0;

	public void guess()
		{
		number = (int) (Math.random() * 10);
		System.out.println("I'm guessing " + number);
		}

	}

GuessGame.java does NOT compile:

public class GuessGame
	{
	Player p1;
	Player p2;
	Player p3;
	Public void StartGame()
		{
		p1 = new Player();
		p2 = new Player();
		p3 = new Player();

		int guessp2 = 0;
		int guessp3 = 0;

		boolean p1isRight = false;
		boolean p2isRight = false;
		boolean p3isRight = false;

		int targetNumber = (int) (Math.random() * 10);
		System.out.println("I'm thinking of a number between 0 and 9...");

		while(true)
			{
			System.out.println("Number to guess is " + targetNumber);

			p1.guess();
			p2.guess();
			p3.guess();
			
			guessp1 = p1.number;
			System.out.println("Player one guessed " + guessp1);

			guessp2 = p2.number;
			System.out.println("Player two guessed " + guessp2);

			guessp3 = p3.number;
			System.out.println("Player three guessed " + guessp3);

			if (guessp1 == targetNumber)
				{
				p1isRight = true;
				}

			if (guessp2 == targetNumber)

				System.out.println("We have a winner!");
				System.out.println("Player one got it right? " + p1isRight);
				System.out.println("Player two got it right? " + p2isRight);
				System.out.println("Player three got it right? " + p3isRight);
				System.out.println("Game is over.");
				break;
				}
			else
				{
				System.out.println("Players will have to try again.");
				}

			}

Hi,
Java IS case sensitive. So, "Public" is not the same as the actual java keyword "public". This should solve some of your issues here.

Thanks! OK, did that, now I only get this:
(I know game must be the game in the line above it in GameLauncher - it is there, but the compiler says it can't find it: )

Is this something that is so obvious I should "just see it" or "jsut get it?"

Again case sensitive - StartGame() and not startGame()

Thanks, John. So sorry, how embarrassing, am told by someone look at CASE SENSITIVITY and there is my problem again.
I trust I'll not repeat that one again!

Thanks again, Lokesh and John!
