    Default occurrence of int in array..

    Can i have code for the given problem please......

    (Count occurrence of numbers) Write a program that reads the integers between 1
    and 100 and counts the occurrences of each. Assume the input ends with 0. Here is
    a sample run of the program:
    Enter the integers between 1 and 100: 2 5 6 5 4 3 23 43 2 0
    2 occurs 2 times
    3 occurs 1 time
    4 occurs 1 time
    5 occurs 2 times
    6 occurs 1 time
    23 occurs 1 time
    43 occurs 1 time

    Note that if a number occurs more than one time, the plural word “times” is used
    in the output.

    Can you post the code you have written for this program and any questions about the problems you are having?

    Be sure to wrap your code with code tags:
    [code=java]
    YOUR CODE HERE
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    This is the following code i have written.. i am bit new to programming so please help me out.
     public static void main(String[] args) {
            Scanner input = new Scanner(System.in);
            int[] num = new int[100];
            int count = 0;
     
            System.out.println("Enter the integers between 1 and 100");
              for(int i = 0 ; i < num.length ; i++){
                num[i] = input.nextInt();
            if(num[i] == 0)
                break;
              }
        for(int i = 0 ; i < num.length ; i++)
        {
            for(int j = 0 ; j > i ; j++)
            {
                if(num[i] == num[j])
                    count++;
               }
           for( i = 0 ; i < num.length ; i++)

    Post the program's output
    and also post what you want the output to look like.

    What happens when you compile and execute the program? Copy the full contents of the console from when the program is compiled and executed and paste it here.

    What part of the assignment is working?
    What steps are you having problems with?
    If you don't understand my answer, don't ignore it, ask a question.

    Did you see my questions in the last post?
    1)What part of the assignment is working?
    2)What steps are you having problems with?

    How should the code use the int[100] array for counting what the user enters? Why is the array so large if the user is only going to enter a few numbers? Should the array hold the numbers that the user enters? What if the user wanted to enter 200 numbers?

    Did your instruction tell you about how to use a number to index into an array to get at an element in the array? Could the number that a user enters be used as an index to the array?
    If you don't understand my answer, don't ignore it, ask a question.
