Write an expression that executes the loop body as long as the user enters a non-negative number. note: these activities may test code with different test values. this activity will perform three tests, with user input of 5, 2, -1, then with user input of -17, then with user input 1, 0, -1. see how to use zybooks. also note: if the submitted code has an infinite loop, the system will stop running the code after a few seconds, and report "program end never reached." the system doesn't print the test case that caused the reported message. import java. util. scanner; public class nonnegativelooper {public static void main (string [] args) {scanner scnr = new scanner(system. in); int usernum = 0; while (/* your solution goes here */) {
