    Default Re: }while(guess1!=gen1) ';' expected Compiler error

    My program keeps throwing this compiler error and my program is due by 12. Cannot figure this out. Please help.


    import java.util.Scanner;
    import java.util.Random;

    //Michael Morris CSC151

    public class PP4_8
    {
    public static void main (String [] args)
    {
    Random generator=new Random();
    Scanner scan=new Scanner(System.in);

    final int MAX=100;
    int gen1;
    int guess1;
    int sum;

    gen1=generator.nextInt(MAX)+ 0;


    while (another.equalsIgnoreCase("y"))
    {
    while(guess1!=0)
    {
    do
    {

    System.out.println("I'm thinking of a number betweeen 1 and Max" +MAX +"can you guess what it is:");
    guess1=scan.nextInt();

    sum=guess1;
    if(guess1==gen1)
    System.out.println("The guess is correct");
    if(guess1<gen1)
    System.out.println("The guess is too low");
    if(guess1>gen1)
    System.out.println("The guess is too high");

    System.out.println("The sum of guesses are:" +sum);

    }while(guess1!=gen1)

    System.out.println("Do you want too play again enter y for yes");
    another=scan.nextLine();
    }
    }
    }

    }

    compiler error
    Please copy the full text of the error message and paste it here. It has important info about the error.

    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE GOES HERE
    [/code]
    to get highlighting and preserve formatting.

    Make sure the indentations are done properly for nested statements.

    What happens when you add a ; where the compiler wants one?
    If you don't understand my answer, don't ignore it, ask a question.

    }while(guess1!=gen1) ';' expected- this is the error message

    If I add a semicolon ; at that while(guess1!=gen1) then I get another compiler error message of can't find the symbol at this while
    statement while (another.equalsIgnoreCase("y"))

    The formatting is all messed up. The nested statements aren't properly indented. Only one } should be in the first column. The other }s need to be in column beneath the start of the statements with the pairing {.
    It's almost impossible to read and understand the code as it is now formatted.

    Please copy the full text of the error message and paste it here. It has important info about the error.

    Is that the same error? Add a ; where the compiler says to.

    I did that and got another compiler error message of can't find the symbol at the while
    statement "while (another.equalsIgnoreCase("y"))". Never heard of a semicolon on a while statement.

    Why don't you post your full code. What is "another"?

    You aren't giving another any value are you? You are putting it in the while loop as a condition before giving it a value//
