Question

Using Figure 6-10 on page 293 as a guide, use NetBeans IDE and write a CLI application that does following: 

• Ask for a number between 1-5 from user . 

• You pick one number from 1-5 and use it as the correct number:

• If the user specified number is not correct, output the incorrect number and ask the user to enter it again.

• If the user specified number is correct, output the correct number, thank the user for participating, and terminate the program. .




Finally, take a screenshot of your CLI outputs and then submit it along with your zipped NetBeans project folder of this exercise to e-Learning. 

Answer 1

Code:

import java.util.Scanner;
import java.util.Random;

public class EnterSmallValue
{
   public static void main(String [] args)
   {
       int userEntry;
      
       Scanner input = new Scanner(System.in);
       System.out.println("Please enter an integer between 1 - 5");

       Random r = new Random();

       int correctNumber = r.nextInt(5) + 1;
       userEntry = input.nextInt();
       while(userEntry != correctNumber)
       {
           System.out.println("The number :" + userEntry + " you entered was not correct. Try again ");
           System.out.println("Please enter an integer between 1 - 5");
           userEntry = input.nextInt();
       }
       System.out.println("The correct number is " +userEntry);
       System.out.println("Thanks for participating");
      
   }
}
