Hi.

In your code, you send two parameters to the num method, a[] and i.

I am going to assume that i is the number that needs to be tested for.

So...

In your code, make sure you check every number in the array by using j as the index for the array. Also, you should not create a again inside the method, as that would then remove the parameter passed to this object. I added a main method to make it easier to test the code. Running the example below, the output should be 3.

public class NumOccurrences
{
public static int num(int[] a, int i) {
int count = 0;
for (int j = 0; j < a.length; j++) {
if (a[j] == i) {
count++;
}
}
return count;
}

public static void main(String[] args) {
int[] array = {5, 6, 4, 1, 6, 4, 5, 1, 2, 6, 8, 9};
System.out.println("Counted " + num(array, 6));
}
}
