(16) 6. You want to write a Java application that creates a while loop that runs until the user enters a 0 as input. Each time the while loop runs, it displays a menu of three choices as will be shown in the sample run below. When the program reads in the user's choice, that choice should be read in as a String called choiceStr. Then, choiceStr should be converted into an int called choice by using the code below: int choice = Integer.parseInt(choiceStr); If the user enters a 1 for choice == 1, the program will print "Choice 1" to the screen. If the user enters a 2 for choice == 2, the program will print "Choice 2" to the screen. Here is a sample run: 0 - to quit 1 to print Choice 1 2 to print Choice 2 Enter choice: 1 Choice 1 0 - to quit 1 to print 2 to print Enter choice: 1 Choice 1 Choice 2 Choice 1 0 - to quit 1 to print Choice 1 2 to print Choice 2 Enter choice: 2 Choice 2 0 - to quit 1 to print Choice 1 2 to print Choice 2 Enter choice: 0

Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.
Question
Transcribed Image Text:(16) 6. You want to write a Java application that creates a while loop that runs until the user enters a 0 as input. Each time the while loop runs, it displays a menu of three choices as will be shown in the sample run
below. When the program reads in the user's choice, that choice should be read in as a String called choiceStr. Then, choiceStr should be converted into an int called choice by using the code below:
int choice Integer.parseInt(choiceStr);
If the user enters a 1 for choice == 1, the program will print "Choice 1" to the screen. If the user enters a 2 for choice == 2, the program will print "Choice 2" to the screen. Here is a sample run:
0 - to quit
1
to print Choice 1
2 to print Choice 2
Enter choice: 1
Choice 1
0 - to quit
1 to print
Choice 1
2 to print Choice 2
Enter choice: 1
Choice 1
0
to quit
1
to print Choice 1
2 to print Choice 2
Enter choice: 2
Choice 2
0 - to quit
1 to print Choice 1
2 to print Choice 2
Enter choice: 0
Expert Solution
Step 1
Code in java:
import java.util.*;
public class WhileExample {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
String choiceStr;
int choice = 1;
while (choice != 0) {
System.out.println("0- to quit");
System.out.println("1- to print choice 1 ");
System.out.println("2- to print choice 2 ");
System.out.print("Enter a Choice: ");
choiceStr = sc.nextLine();
choice = Integer.parseInt(choiceStr);
switch (choice) {
case 0:
System.out.println("Choice 0");
break;
case 1:
System.out.println("Choice 1");
break;
case 2:
System.out.println("Choice 2");
break;
}
}
}
}
