Counting an Occurrence in an Array (Java)

Question

I am completely stumped. I took a break for a few hours and I can\'t seem to figure this one out. It\'s upsetting!

I know that I need to check the current element in

@NYB You're almost right but you have to output the count value and also start it from zero on each element check.

    int count=0,currentInt=0;
    for (int i = 0; i < numbers.length; i++)
    {
    currentInt = numbers[i];
    count=0;

       for (int j = 0; j < numbers.length; j++)
           {
             if (currentInt == numbers[j])
                {
                  count++;
                 }
            }
            System.out.println(count);
      }

@loikkk I tweaked your code a bit for print out of occurrence for each element.

int[] a = { 1, 9, 8, 8, 7, 6, 5, 4, 3, 3, 2, 1 };

    Arrays.sort(a);

    int nbOccurences = 1;

    for (int i = 0, length = a.length; i < length; i++) {
        if (i < length - 1) {
            if (a[i] == a[i + 1]) {
                nbOccurences++;
            }
        } else {
            System.out.println(a[i] + " occurs " + nbOccurences
                    + " time(s)"); //end of array
        }

        if (i < length - 1 && a[i] != a[i + 1]) {
            System.out.println(a[i] + " occurs " + nbOccurences
                    + " time(s)"); //moving to new element in array
            nbOccurences = 1;
        }

    }
