    Default How to limit the input numbers?

    Suppose I want to limit the input numbers to 20 in the following program, what should I do?


    private static void Question2(){
    Scanner scr = new Scanner(System.in);
    int count = 0;

    System.out.println("How many numbers are you going to enter (not greater than 20)");
    int n = scr.nextInt();
    int[] num = new int[n]; // num is an array of n integers

    System.out.printf("Enter %d numbers\n", n);
    for (int i = 0; i < num.length; i++) {
    num[i] = scr.nextInt();
    }

    System.out.println("Pick a number");
    int x = scr.nextInt();

    for (int i = 0; i < num.length; i++) {
    if(num[i] == x) {
    count++;
    }
    }
    System.out.printf("You entered %d occurence of %ds\n", count , x);

    }

    Check the value of n and if it is greater than 20, inform the user and ask for a new number.

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
