You are only outputting your loop variables i
& j
. You need to access the array at those positions:
System.out.println("Pair: " + array[i] + " and " + array[j]);
This will only print out 1 matching pair because of the return
. If you need more, you'll need to remove that & use a variable to control whether or not the message gets printed.
