Question

Write a do-while loop that continues to prompt a user to enter a number less than 100, until the entered number is actually less than 100. End each prompt with newline Ex: For the user input 123, 395, 25, the expected output is: Enter a number (<100): Enter a number (<100): Enter a number (<100): Your number < 100 is: 25 import java.util.Scanner; public class NumberPrompt { public static void main (String [] args) { Scanner scnr = new Scanner(System.in); int userInput = 0; /* Your solution goes here */ System.out.println("Your number < 100 is: " + userInput); return; } }

Answer 1

Screenshot of the code:

port java.util.Scanner; im //Declare the class NumberPrompt public class NumberPrompt public static void main(String args []) /*Declare the variable of scanner class and allocate the memory.*/ scanne r scnr = new scann er (system. 1끄); //Initialize the variable userInput. int userInput 0 *Your solution goes here/ //start the do-while loop do //Prompt the user to enter the number. System.out.println("Enter a number (<100)" /*Store the number entered by the user in the user1nput=scnr .nextint () ; variable userInput.*/ while (userInput>-100)Run the do-while loop till the user input is greater than 100*/ /Print the number which is less than 100. system . ou t . println("Your number <100 İs "tuserinput); return;

Sample Output:

Enter a number (<100) 123 Enter a number (<100) 395 Enter a number (<100) 25 Your number <100 is 25

Code to copy:

import java.util.Scanner;

//Declare the class NumberPrompt.

public class NumberPrompt

{

   public static void main(String args[])

   {

        /*Declare the variable of scanner class and allocate the

        memory.*/

        Scanner scnr = new Scanner(System.in);

       

        //Initialize the variable userInput.

        int userInput = 0;

        /* Your solution goes here*/

        //Start the do-while loop

        do

        {

          //Prompt the user to enter the number.

          System.out.println("Enter a number(<100)");

         

          /*Store the number entered by the user in the

          variable userInput.*/

          userInput=scnr.nextInt();

            

        }while(userInput>=100);/*Run the do-while loop till the    

        user input is greater than 100*/

       

        //Print the number which is less than 100.

        System.out.println("Your number <100 is "+userInput);

        return;

   }

}
