Loop Ch 4.9 Exam Questions & Answers2024/2025
while loop - ANSWERSis a pretest loop. It is ideal in situations where you do not want the loop to iterate
if the condition is false from the beginning. It is also ideal if you want to use a sentinel value to terminate
the loop.
do-while loop - ANSWERSis a posttest loop. It is ideal in situations where you always want the loop to
iterate at least once.
for loop - ANSWERSis a pretest loop that has built-in expressions for initializing, testing, and updating.
These expressions make it very convenient to use a loop control variable as a counter. The for loop is
ideal in situations where the exact number of iterations is known.
Modify the following program to use a while loop instead of a do while loop. Think about which one you
prefer and why.
import java.util.Scanner;
public class WhichLoop
{
public static void main(String[] args)
{
Scanner keyboard = new Scanner(System.in);
String input;
char sure;
//modify
do
{
System.out.print("Are you sure you want to quit? ");
