Question

Prompt the user to input an integer, a double, a character, and a string, storing each into separate variables. Then, output those four values on a single line separated by a space.

Answer 1

Answer:

import java.util.Scanner;

public class ANot {

   public static void main(String[] args) {

Scanner in = new Scanner(System.in);

// Prompt user for an integer

       System.out.println("Please enter an Integer");

       int intNum = in.nextInt();

       // Prompt user for an double

       System.out.println("Please enter a double");

       double DoubleNum = in.nextDouble();

       // Prompt user for a character

       System.out.println("Please enter a Character");

       char charNum = in.next().charAt(0);

       // Prompt user for a String

       System.out.println("Please enter a String");

       String StringNum = in.next();

       System.out.println(intNum+" "+DoubleNum+" "+charNum+" "+StringNum);

   }

}

Explanation:

We import the Scanner class in order to receive user input. Then we create four different variables of type int, double,char and String to hold the values entered by the user.

To display the output on a single line, we use string concatenation (using the + operator) to acheive this.
