/**
 * 13.16 (Create a rational-number calculator) Write a program similar to Listing 7.9,
 * Calculator.java. Instead of using integers, use rationals, as shown in Figure 13.10a.
 * You will need to use the split method in the String class, introduced in
 * Section 10.10.3, Replacing and Splitting Strings, to retrieve the numerator string and
 * denominator string, and convert strings into integers using the Integer.parseInt
 * method.
