1. Create a class called Complex for performing arithmetic with complex numbers. Complex

numbers have the form

where ?? is ??1

???????????????? + ?????????????????????????? ? ??

Write a program to test your class. Use double variable to represent the private data of the class. Provide a constructor that enables an object of this class to be initialized when it’s declared. Provide a no-argument constructor with default values in case no initializers are provided. Provide public methods that perform the following operations:

a) Add two Complex numbers: The real parts are added together and the imaginary parts are added together.

b) Subtract two Complex numbers: The real part of the right operand is subtracted from the real part of the left operand, and the imaginary part of the right operand is subtracted from the imaginary part of the left operand.

c) Print Complex numbers in the form (??, ??) where ?? the real part and ?? is the imaginary part.

Explanation / Answer

Complex.java

public class Complex {
// Declaring variables
private double x, y;
//Parameterized constructor
public Complex(double x, double y) {
super();
this.x = x;
this.y = y;
}
//One argumented constructor
public Complex(double x) {
super();
this.x = x;
this.y = 0;
}
//Zero argumented constructor
public Complex() {
this.x = 0;
this.y = 0;
}
//Getters
public double getX() {
return x;
}
public double getY() {
return y;
}
/* This method will add the two complex numbers
* return a Complex number class object
*/
public Complex add(Complex c) {
Complex comp = new Complex();
comp.x = this.x + c.x;
comp.y = this.y + c.y;
return comp;
}
/* This method will subtract the two complex numbers
* return a Complex number class object
*/
public Complex sub(Complex c) {
Complex comp = new Complex();
comp.x = this.x - c.x;
comp.y = this.y - c.y;
return comp;
}

/*
* toString() method is used to display the contents of an object inside it
*/
@Override
public String toString() {
return "("+x + ", " + y + ")";
}
}

Test.java

import java.util.Scanner;

public class Test {

public static void main(String[] args) {

int real1,imag1,real2,imag2;

/*

* Creating an Scanner class object which is used to get the inputs

* entered by the user

*/

Scanner sc = new Scanner(System.in);

//Getting the input entered by the user

System.out.print("Enter the real part of the first complex number :");

real1=sc.nextInt();

System.out.print("Enter the imaginary part of the first complex number :");

imag1=sc.nextInt();

System.out.print("Enter the real part of the second complex number :");

real2=sc.nextInt();

System.out.print("Enter the imaginary part of the second complex number :");

imag2=sc.nextInt();

//Creating an Instance of Complex Number

Complex c1=new Complex(real1, imag1);

//Creating an Instance of Complex Number

Complex c2=new Complex(real2, imag2);

//calling the add() method on the Complex Class

Complex addRes=c1.add(c2);

//calling the sub() method on the Complex Class

Complex subRes=c1.sub(c2);

//Displaying the Output

System.out.println("First Complex Number :"+c1);

System.out.println("Second Complex Number :"+c2);

System.out.println("Addition of complex numbers is :"+addRes);

System.out.println("subtraction of complex numbers is :"+subRes);

}

}

Output:

Enter the real part of the first complex number :3
Enter the imaginary part of the first complex number :6
Enter the real part of the second complex number :2
Enter the imaginary part of the second complex number :7
First Complex Number :(3.0, 6.0)
Second Complex Number :(2.0, 7.0)
Addition of complex numbers is :(5.0, 13.0)
subtraction of complex numbers is :(1.0, -1.0)
