    Default Java - eclipse (HiLo guessing game)

    Hi, I am having a hard time determining what the problem is with my codes. I have started over multiple times and I am getting at least 12 error messages. I am a beginner so this appears to be difficult. My assignment is to design & implement an application that plays the Hi-Lo guessing game with numbers (between 1 & 100) then repeatedly prompt the user to guess the number. I have used an online template to get what I have and this is what I have so far...
    [code=Java]
    import java.util.Scanner;
    import java.util.Random;

    public class HiLoGuess {

    public static void main(String[] args) {
    // TODO Auto-generated method stub

    }
    Scanner input = new Scanner(System.in);
    Random rand = new Random();
    int number = rand.nextInt(100) + 1;
    int guess;
    private Scanner scan;


    System.out.println("Guess a number between 1 and 100");


    guess = scan.nextInt();

    while (guess < number) {
    System.out.println("Higher!");
    guess = scan.nextInt();
    }
    while (guess > number) {
    System.out.println("Lower!");
    guess = scan.nextInt();
    }
    while (guess == number) {
    System.out.println("Correct!");
    break;
    }
    }
    }




    }

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

    I got rid of your private scanner and replaced all guess = scan.nextInt(); with guess = input.nextInt();
    and it works fine..
