How do I loop this?

[Crosson]

Here is my code:

  
    System.out.println("Please enter the number you think the die will roll. The number must be between 1 and 6");
    for (boolean numRun=true; numRun;) {
            Scanner sc = new Scanner(System.in);
            if (sc.hasNext()) {
                numInput = sc.nextInt();
                if (numInput >= 1 && numInput <= 6) {
                    numRun= false;
                    System.out.println("The number you have entered is between 1 and 6");
                } else {
                    System.err.println("You have entered an incorrect value.");
                    numRun=true;
                    
                }
            }
    }

How do i write the code so that it keeps asking the same questions until the value the user entered is in the 1 to 6 parameters?

Use a while loop instead of a for loop.

okay i changed the code a little bit:

    System.out.println("Please enter the number you think the die will roll. The number must be between 1 and 6");
    for (boolean numRun=true; numRun;) {
        Scanner sc = new Scanner(System.in);

        int numInput = sc.nextInt();
        if(numInput >= 1 && numInput <= 6) {
            int number = numInput;
            numRun = false;
        } else {
            System.out.println("The # you entered is not between 1 and 6. Please re-enter a number.");
            numRun = true;
        }
    }
    System.out.println(number);

And I think the loop will work fine, but what my problem is that the variable number cannot be found outside of the loop. How do i get the variable outside the loop?

[Rabbit]

Declare the variable outside the loop

i declared the variable 'number' outside the loop ... but now my program is saying the the variable might not have been initialized

[Rabbit]

Initialize it to 0

thanks for the help !
