A variable like userNum can store a value like an integer. Extend the given program to print userNum values as indicated. (1) Output the user's input. Enter integer: 4 You entered: 4(2) Extend to output the input squared and cubed. Hint: Compute squared as userNum * userNum. (Submit for 2 points, so 4 points total).Enter integer: 4 You entered: 44 squared is 16 And 4 cubed is 64 Enter another integer: 5 4 + 5 is 9 4 * 5 is 20import java. util. Scanner;public class OutputWithVars {public static void main(String[] args) {Scanner scnr = new Scanner(System. in);int userNum = 0;System. out. println("Enter integer: ");userNum = scnr. nextInt();return;}}

Write the following lines of code just before the return statement

//1

       System.out.println("You entered "+userNum);        

       // 2

       System.out.println(userNum+" squared is "+(Math.pow(userNum, 2))+" and "+userNum+" cubed is "+(Math.pow(userNum, 3)));

       //3

       int userNum2 = 0;

       System.out.print("Enter another integer: ");

       userNum2 = scnr.nextInt();

int sum = userNum + userNum2;

       System.out.println(userNum+" + "+userNum2+" is "+sum);

int product = userNum * userNum2;

       System.out.println(userNum+" * "+userNum2+" is "+product);

Explanation:

I continued the program from where you stopped in the question
