I am confused on this

Question

(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.

Enter integer: 4
You entered: 4
4 squared is 16
And 4 cubed is 64!!

(3) Extend to get a second user input into userNum2. Output sum and product.

Enter integer: 4
You entered: 4
4 squared is 16
And 4 cubed is 64!!
Enter another integer: 5
4 + 5 is 9
4 * 5 is 20

This is what I got so far on it. I'm hoping someone could help me on it and I can look over it to see how you did it for reference thanks.

import 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 another integer: ");
userNum = scnr.nextInt();

return;
}
}

Answer 1

For square and cube
int sq = userNum * userNum;
int cube = userNum * userNum * userNum;

For product and and addition:
Simply take 2nd numbers from user and multiply the input with first input and store it in some variable and same with addition.
