Basic output with variables (java) this zylab activity is intended for students to prepare for a larger programming assignment. warm up exercises are typically simpler and worth fewer points than a full programming assignment. warm up exercises are ideally suited for an in-person scheduled lab meeting or as self-practice. the last section provides a full programming assignment. a variable like usernum can store a value like an integer. extend the given program to print usernum values as indicated. (submit for 2 points) (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: 4 4 squared is 16 and 4 cubed is (3) extend to get a second user input into usernum2. output sum and product. (submit for 1 point, so 5 points total). enter integer: 4 you entered: 4 4 squared is 16 and 4 cubed is enter another integer: 5 4 5 is 9 45 is 20 lab 1.16.1: basic output with variables (java) 0/5 activity outputwithvars. java load default 1 import java. util. scanner; 2 3 public class outputwithvars public static void main(string [] args) scanner scnr new scanner(system. in); int usernum - 0 6 7 system. out. println ("enter integer: ") usernum scnr. next int ( ) ; 9 10 return; 11 12 13
