I need to create a function that will accept two arrays of integers. Display the combinations and the number of combinations without the same value.

Example:

Array 1 = { 1, 2, 3 }; 
Array 2 = { 2, 3, 4 };

Output :

1,2
1,3
1,4
2,3
2,4
3,2
3,4

Combination count : 7

I've seen a lot of complicated codes here and can't find the exact goal that I am looking for so far, While waiting for someone to help I will just keep browsing and searching. Also I'm using Java 7.

Try this.

Note: This code is considering given example. There are no validation done. You can add it if needed.

int count = 0;

        for (int i = 0; i < array.length; i  ) {
            for (int j = 0; j < array2.length; j  ) {
                if(array[i] != array2[j]){
                    System.out.println("Combination " array[i] " " array2[j]);
                    count = count  1;
                }
            }
        }
        System.out.println("Combination " count);
