How to count whether any number in an array repeated twice or thrice

import java.util.Arrays;
import java.util.Collections;
import java.util.HashSet;
import java.util.List;
import java.util.Set;
import java.util.stream.Collectors;

public class NumOfPairsAndTriplets {

	public static void main(String[] args) {
		//To count the number of pairs and triplets in an array of integers.

		int [] numArray= {91,43,54,91,36,91,14,43,17,28,36,54,43};
		int numberOfPairs=0,numberOfTriplets=0;

		//Display the existing array of integers
		System.out.println("The given array of integers is below");
		System.out.print("[ ");
		for(int i=0;i<numArray.length;i++) {
			System.out.print(numArray[i]+" ");
		}
		System.out.println("]");

		//Converting the array of integers to ArrayList using Arrays class
		List<Integer> arrIntList=Arrays.stream(numArray).boxed().collect(Collectors.toList());
		Set<Integer> uniqueInts=new HashSet<Integer>(arrIntList);

		//Use the Collections class to check frequency of any of ArrayList integers is to 2 or 3
		for (int numInt: uniqueInts) {
			if (Collections.frequency(arrIntList,numInt)==2) {
				numberOfPairs++;
			}
			if (Collections.frequency(arrIntList,numInt)==3) {
				numberOfTriplets++;
			}
		}
		System.out.println("Total number of Pairs, available in the given array are = "+numberOfPairs);
		System.out.println("Total number of Triplets, available in the given array are = "+numberOfTriplets);
