Create a Rational number class in Java using the same style as the Complex number class created in class.(The in class example code is below) That is, implement the following methods:

constructor

add s

ub

mul

div

toString

You must also provide a Main class and main method to fully test your Rational number class.

Example code:

public class Main { public static void main(String[] args) { Complex a = new Complex(2.0, 3.0); Complex b = new Complex(1.0, 2.0); System.out.println(a + " + " + b + " = " + a.add(b)); System.out.println(a + " - " + b + " = " + a.sub(b)); System.out.println(a + " * " + b + " = " + a.mul(b)); System.out.println(a + " / " + b + " = " + a.div(b)); } } class Complex { public Complex(double re, double im) { real = re; imag = im; } public Complex add(Complex o) { return new Complex(real + o.real, imag + o.imag); } private Complex conjugate() { return new Complex(real, -imag); } public Complex div(Complex o) { Complex top = mul(o.conjugate()); Complex bot = o.mul(o.conjugate()); return new Complex(top.real / bot.real, top.imag / bot.real); } public Complex mul(Complex o) { return new Complex(real * o.real - imag * o.imag, real * o.imag + imag * o.real); } public Complex sub(Complex o) { return new Complex(real - o.real, imag - o.imag); } public String toString() { return "(" + real + " + " + imag + "i)"; } private double real; private double imag; }
