Make a program in Java Object Oriented language that performs Addition, Subtraction, Multiplication of two complex numbers (a+bi)

import java.util.Scanner;
public class Test{
//main method
public static void main(String[] args){
Scanner input=new Scanner(System.in);
System.out.print("Enter the first complex number: ");
double a=input.nextDouble();
double b=input.nextDouble();
Complex c1=new Complex(a,b);

System.out.print("Enter the second complex number: ");
double c=input.nextDouble();
double d=input.nextDouble();
Complex c2=new Complex(c,d);
System.out.println("("+c1+")"+" + "+"("+c2+")"+" = "+c1.add(c2));
System.out.println("("+c1+")"+" - "+"("+c2+")"+" = "+c1.subtract(c2));
System.out.println("("+c1+")"+" * "+"("+c2+")"+" = "+c1.multiply(c2));
System.out.println("("+c1+")"+" / "+"("+c2+")"+" = "+c1.divide(c2));
System.out.println("|"+c1+"| = "+c1.abs());
System.out.println();
