The Rational class in this chapter extends java.lang.Number and implements java.lang.Comparable. Analyze the following code.

1. public class Test {
2.public static void main(String[] args) {
3.Number[] numbers = {new Rational(1, 2), new Integer(4), new Double(5.6)};
4.java.util.Arrays.sort(numbers);
5.}
6. }

◦ The program has a runtime error because numbers is declared as Number[], so you cannot assign {new Rational(1, 2), new Integer(4), new Double(5.6)} to it.
◦ The program has a compile error because numbers is declared as Number[], so you cannot pass it to Arrays.sort(Object[]).
◦ The program has a compile error because numbers is declared as Number[], so you cannot assign {new Rational(1, 2), new Integer(4), new Double(5.6)} to it.
◦ The program has a runtime error because the compareTo methods in Rational, Integer, and Double classes do not compare the value of one type with a value of another type.

Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
