Cannot able to get the Output

[Zakir Hosain]

I have done this problem from "Head First Java" Chapter 2 - Page 39.
I am not getting the out put.
-------------------------------
I am getting the Error Below:

C:\Program Files\Xinox Software\JCreatorV3LE\MyProjects\ClassesandObjects2007\GameLauncher.java:1: class GuessGame is public, should be declared in a file named GuessGame.java
public class GuessGame
^
C:\Program Files\Xinox Software\JCreatorV3LE\MyProjects\ClassesandObjects2007\GameLauncher.java:74: class Player is public, should be declared in a file named Player.java
public class Player

location: class java.io.PrintStream
System.out.prinln("Player one guessed" + guessp1);
^
3 errors

----------------------------------------------------------------

// The coding is below:


public class GuessGame
{
Player p1;
Player p2;
Player p3;

public void startGame()
{
p1 = new Player();
p2 = new Player();
p3 = new Player();

int guessp1 = 0;
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 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.prinln("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)
{
p2isright = true;
}

if (guessp3 == targetNumber)
{
p3isright = true;
}

if (p1isright || p2isright || p3isright)
{
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 theee got it right" + p3isright);
System.out.println("Game is over.");
break;
}

else
{
System.out.println("Players will have to try again.");
}
}
}
}

public class Player
{
int number = 0;
public void guess()
{
number = (int) (Math.random() * 10);
System.out.println("I'm guessing" + number);
}
}

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

In java you can have only one public class in a source code file. So remove public class from GuessGame and Player.

Error 3 is a typo. It should have been

   
 System.out.println("Player one guessed" + guessp1);

I hope this helps

Believe it or not, those error messages tell you a lot. You should learn to read them and understand what they mean.

the first two tell you EXACTLY what you need to do: "class GuessGame is public, should be declared in a file named GuessGame.java"

in other words: Since the class GuessGame has the 'public' modifier in front of it, you must create a second, separate file called 'GuessGame.java', and put all the code for THAT class there.


The third error messages says "i have no idea what you are talking about. the specific thing i don't understand is this symbol: prinln(java.lang.String) - oh, and it's some kind of method."

you can then search your code for that symbol (although it also tells you it's line 32). often it's either a typo or you don't have an import correct. in this case, it's pretty obvious you meant println.
