Question

I need some help generating a UML diagram from this assigment.

Design a class named Complex for representing complex numbers with the methods add,
subtract, multiply, divide, and abs for performing complex number operations, and
override toString method for returning a string representation for a complex number. The
toString method returns (a + bi) as a string. If b is 0, it simply returns a. Your Complex
class should also implement Cloneable and Comparable. Compare two complex numbers
using their absolute values.
Provide three constructors Complex(a, b), Complex(a), and Complex(). Complex()
creates a Complex object for number 0, and Complex(a) creates a Complex object with 0
for b. Also provide the getRealPart() and getImaginaryPart() methods for returning the
real part and the imaginary part of the complex number, respectively.

Step 1 of 2

public class Complex implements Cloneable {

    private double a;
    private double b;

    public Complex(double a, double b) {
        this.a = a;
        this.b = b;
    }

    public Complex(double a) {
        this.a = a;
        b = 0;
    }

    public Complex() {
        this.a = 0;
        this.b = 0;
    }

    public double getRealPart() {
        return this.a;
    }

    public double getImaginaryPart() {
        return this.b;
    }

    @Override
    public String toString() {
        if (b < 0) {
            return this.a + " " + this.b + "i";
        } else if (b > 0) {
            return this.a + " + " + this.b + "i";
        } else {
            return String.valueOf(this.a);
        }
    }

    @Override
    protected Object clone() throws CloneNotSupportedException {
        return super.clone();
    }

    public Complex add(Complex c) {

        double real = this.a + c.getRealPart();
        double imag = this.b + c.getImaginaryPart();

        return new Complex(real, imag);

    }

    public Complex subtract(Complex c) {

        double real = this.a - c.getRealPart();
        double imag = this.b - c.getImaginaryPart();

        return new Complex(real, imag);

    }

    public Complex multiply(Complex c) {

        double real = this.a * c.getRealPart();
        double imag = this.b * c.getImaginaryPart();

        return new Complex(real, imag);

    }

    public Complex divide(Complex c) {

        double real = this.a / c.getRealPart();
        double imag = this.b / c.getImaginaryPart();

        return new Complex(real, imag);

    }

    public Complex abs() {

        double real = this.a < 0 ? -this.a : this.a;
        double imag = this.b < 0 ? -this.b : this.b;

        return new Complex(real, imag);

    }
}
