If you need to mock some requests Mockoon is a very handy tool for it

Does given array contains a triplet (a^2 + b^2 = c^2) ?

 

	package com.company;
	import java.math.BigInteger;
	import java.util.ArrayList;
	import java.util.Collections;
	import java.util.List;
	public class TripletFounder {
	public static void main(String[] args) {
	Integer[] array = {3, 1, 4, 6, 5};
	double pow = (int) Math.pow(2, array.length);
	for (int i = 0; i < pow; i++) {
	List<Integer> subsSeqWithSize3 = new ArrayList<>();
	for (int j = 0; j < array.length; j++) {
	if (BigInteger.valueOf(i).testBit(j)) {
	System.out.print(array[j] + " ");
	subsSeqWithSize3.add(array[j]);
	}
	}
	if (subsSeqWithSize3.size() == 3) {
	Collections.sort(subsSeqWithSize3);
	if (Math.pow(subsSeqWithSize3.get(0), 2) + Math.pow(subsSeqWithSize3.get(1), 2) == Math.pow(subsSeqWithSize3.get(2), 2)) {

	System.exit(0);
	}
	}
	System.out.println("");

Your custom java annotation and check for it on the classes with reflection

Just another copy paste run bye article !
