I need help finding the multiple from this array in java.

public class LastMultipleofThree public static void main(String[] args) int[] numbers1 = {76, 75, 3, 17, 12, 22, 7}; System.out.print("The following index holds the LAST multiple of 3: " + findMultipleOfThree (numbers1)); public static int findMultipleOfThree(int[] arr) if(arr.) Write a method called findMultipleofThree that returns the index of the last value in the array that is a multiple of 3. If no index of 3 exists, return-1. For example, in the array [4, 7, 9, 7, 12] the last multiple of three is '12', which occurs at index 4. Sample output: The following index holds the LAST multiple of 3: 4
