Question

1. Ask the user to enter a message
2. Ask the user how many time they want to print the message
3. Then use "while","do-while" and "for" loop to print the message. Show the number at the beginning of the lines when printing.

For example:

Enter your message: Welcome to Java

How many time you want to print this message: 3

Using "while" loop:

1=> Welcome to Java

2=> Welcome to Java

3=> Welcome to Java

Using "do-while" loop:

1=> Welcome to Java

2=> Welcome to Java

3=> Welcome to Java

Using "for" loop:

1=> Welcome to Java

2=> Welcome to Java

3=> Welcome to Java

• Put at least two outputs (two different numbers and results)  (results after you run your code) at the end of your code as a multi-line comment.

/*

Your result

*/

• Don't forget to put your name and a short description of your code on the top on your code.  
• use JAVA

Answer 1

Description : first we read the message and then the message that how many times do you want to print, then we will be printing using 3 loops, that means using the for loop, while loop and do-while loop

import java.util.*;

public class Main
{
   public static void main(String[] args) {
      
       Scanner s = new Scanner(System.in);
       System.out.print("Enter your message : ");
       System.out.println("");
       String str = s.nextLine(); // read the message
       System.out.print("How many time you want to print this message : ");
       System.out.println("");
       int n = s.nextInt(); // read how many times do you want to print
       System.out.println("Using \"while\" loop:");
       int j = 0;
       while(j < n) // print using while loop
       {
       System.out.println((j + 1) +"=> " + str );
       j++;
       }
       System.out.println("Using \"do-while\" loop:");
       int k = 0;
       do // print using do while loop
       {
       if(n == 0)
       {
       break;
       }
       System.out.println((k + 1) +"=> " + str );
       k++;
       }while(k < n); // print using while loop
       System.out.println("Using \"for\" loop:");
       for(int i = 0; i < n; i++)
       {
       System.out.println((i + 1) +"=> " + str );
       }
   }
}
Output :
