2. (25 pts) You are given two classes Complex and ComplexTuple on page 19. They implement complex numbers and tuples of complex numbers, respectively. Hint: In both a and b, below, you are given significantly more space than you should need. a) (10 pts) Add a clone () method to the Complex class; the method must override java.lang. Object's clone () method. The signature is shown below; you just need to fill in the try and catch blocks. @Override public Object clone () { try { Complex c = (Complex) super. clone(); } catch (CloneNot SupportedException e) { Sample code for Problem 2 public class complex implements Cloneable { private int re; // real part private int im; // imaginary part public Complex (int re, int im) { this.re = re; this. im = im; } @Override public boolean equals (Object o) { // Assume this is already implemented; the // implementation details irrelevant. } } public class ComplexTuple { private Complex ci; private complex c2; public Complex Tuple (Complex ci, Complex c2) { this.cl = c1; this.c2 = c2; } }
