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.
