Add two more statements to main() to test inputs 3 and -1. Use print statements similar to the existing one (don't use assert).import java. util. Scanner;public class UnitTesting {// Function returns origNum cubedpublic static int cubeNum(int origNum) {return origNum * origNum * origNum;}public static void main (String [] args) {System. out. println("Testing started");System. out. println("2, expecting 8, got: " + cubeNum(2));/* Your solution goes here */System. out. println("Testing completed");return;}
