4.2.2 Basic while loop with user input. JAVA

Write an expression that executes the loop while the user enters a number greater than or equal to 0.


Note: These activities may test code with different test values. This activity will perform three tests, with user input of 9, 5, 2, -1, then with user input of 0, -17, then with user input of 0 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.

Please use my Template

import java.util.Scanner;

public class NonNegativeLooper {
public static void main (String [] args) {
Scanner scnr = new Scanner(System.in);
int userNum;

userNum = scnr.nextInt();

while (/* Your solution goes here */) {
System.out.println("Body");
userNum = scnr.nextInt();
}
System.out.println("Done.");
}
}

4.9.1: Nested loops: Indent text. JAVA Print numbers 0, 1, 2, ..., userNum as shown, with each number indented by that number of spaces. For each printed line, print the leading spaces, then the number, and then a newline. Hint: Use i and j as loop variables (initialize i and j explicitly). Note: Avoid any other spaces like spaces after the printed number. Ex: userNum = 3 prints: 0 1 2 3 Please use my template import java.util.Scanner; public class...

7.6 LAB: Exception handling to detect input String vs. Integer The given program reads a list of single-word first names and ages (ending with -1), and outputs that list with the age incremented. The program fails and throws an exception if the second input on a line is a String rather than an Integer. At FIXME in the code, add a try/catch statement to catch java.util.InputMismatchException, and output 0 for the age. Ex: If the input is: Lee 18 Lua...
