CISS 110 Dialog Box

5-8. Modify exercise 2-4 where miles per gallon where calculated from the console window. Now modify the program so dialog boxes are used (use all arguments). The prompt and input will be a dialog box instead of a System.out.print() and sc.nextDouble(). The output will be a dialog box instead of a System.out.println(). The input and output will all be the same, but now in dialog boxes. Save as ex58.java and submit it.

* Exercise 2-4

 * This program will calculate miles per gallon   * */  import java.util.Scanner;  public class ex24  {    public static void main(String[] args)    {      double miles, gallons, mpg;    // declare variables      Scanner sc = new Scanner(System.in);        System.out.print("Enter miles:  ");  // prompt      miles = sc.nextDouble();    // input      System.out.print("Enter gallons:  ");      gallons = sc.nextDouble();        mpg = miles / gallons;     // calculate        System.out.printf("Miles per gallon is %.1fn", mpg);  // output    }  }
