help with brakets

[cdm2883]

here is my code, i am having trouble with getting my brakets in the right place so i can run my program.

package mooredMod2;
 
 
import java.util.Scanner;
import java.util.Random;
import java.util.*;
import java.io.*;
 
public class GuessingGame {
 
 
public static void main(String[] args) {
    {
 
    BufferedReader keyboard = new BufferedReader (new InputStreamReader (System.in)); 
        Scanner scan = new Scanner(System.in);
 
 
         boolean more = true; 
 
        Random generator = new Random();
        while (true)
        {
 
 
            String input ; 
 
            int numGuesses = 0; 
 
 
 
            boolean correct = false; 
 
 
 
            int theirGuess ; 
 
 
 
 
            int value; 
             value = generator.nextInt(10) + 1;
             System.out.println ( + value );
 
 
 
 
 
 
             System.out.println("Guess a number between 1 and 10");
 
            while (value < 10 )    // a loop from chapter 5 
            {
                                numGuesses  += 1 ;
 
 
 
 
 
                theirGuess = scan.nextInt ();
 
 
                if(theirGuess<value)
                {
                    System.out.println("Too low!");
 
                }
 
                else if (theirGuess>value)
                {
                    System.out.println("Too high!");
 
                }
 
 
        if (value == theirGuess)
        {
 
                System.out.println("You are correct! "  );    
        }
 
 
        else 
        {
            System.out.println(" You are incorrect guess again! ");
 
 
        }
 
         if (theirGuess == value)
 
        {
            System.out.println("This is how many guesses it took you " + numGuesses  );
 
 
        }            
 
 
         scan.nextLine();
 
 
         if (theirGuess == value)
         {
 
             System.out.println("Would you like to play again? (Eneter true or false)");
             input = keyboard.readLine();
         }
         while(input.equals("Yes"));
         if(input.equals("No"));
         System.exit(0);
 
 
            }
 
 
        }
        }
 
 
 
 
 
 
 
 
 
 
     }//end of main method
 
 
 
}
}
}

We are not here to be a programming equivalent of the 'spellchecker'. Put your code into Notepad and indent it properly, and you will be able to see where extra/missing brackets are. Or, let a program do it for you - get an IDE like BlueJ or Eclipse, or even a text formatting editor like Notepad++, put your code in there, and use the bracket highlighting to find your errors, but don't make us do it in our spare time because you're too lazy.

Listen, I've told you before: Use the [CODE] ... [/code] tags, when posting code! I'm giving you another warning: Use them! If you don't start using them now, consequences will follow soon.

What do you mean use the [CODE] ... [/code] tags

[cdm2883]

But any way i got the brackets fixed. Down at the bottom where i am askin for the user to put true or false. I still cant get that to work, It comes back with this..

Exception in thread "main" java.lang.NullPointerException
at mooredMod2.GuessingGame.main(GuessingGame.java:84)

Can any1 please explain to me what that means and why im getting that.

Thanks

What do you mean use the [CODE] ... [/code] tags

It means, either you write [CODE] before and [/code] after your code, or you click on the # button in the editing window. See the code earlier in this thread? It's in a codebox, which was created through the CODE tags.

Anyway, glad to hear, you've solved the bracket problem. The NullPointerException means, that in line 84 there's a variable, which wasn't declared yet. For example, the code

public class Test {
    public static void main(String[] args) {
        String myWord;
        System.out.println(myWord);
    }
}

would throw a NullPointerException, because it knows there IS something called myWord, but it doesn't have a value yet.

For example, the code

public class Test {
    public static void main(String[] args) {
        String myWord;
        System.out.println(myWord);
    }
}

would throw a NullPointerException, because it knows there IS something called myWord, but it doesn't have a value yet.

Local variables need to be initialized before they can be used. The above yields
a compilation error. Even if you initialize that variable to null explicitly no
NullPointerException is thrown because a PrintStream duly prints "null" when
a null value is passed to its print() method.

kind regards,

Jos
