Write a Java program to find the addition, subtraction, multiplication, and division of two complex numbers using inheritance. Create an abstract class called Complex. From this extends the child classes Addition, Subtraction, Multiplication, and Division. All of these child classes should contain the same methods.Input format :The input consists of four double-type variables, which denote the real and imaginary parts of the first and second complex numbers, respectively.Output format :The output consists of the addition, subtraction, multiplication, and division of the two complex numbers.Refer to the sample input and output for format specifications.Sample test cases :Input 1 :2 64 2Output 1 :Addition: 6.0000 +8.0000 iSubtraction: -2.0000 +4.0000 iMultiplication: -4.0000 +28.0000 iDivision: 1.0000 +1.0000 i

Here is a Java program that performs the operations as per your requirements:

abstract class Complex {
    double real1, real2, imag1, imag2;
    Complex(double r1, double i1, double r2, double i2) {
        real1 = r1;
        imag1 = i1;
        real2 = r2;
        imag2 = i2;
    }
    abstract void add();
    abstract void subtract();
    abstract void multiply();
    abstract void divide();
}

class Addition extends Complex {
    Addition(double r1, double i1, double r2, double i2) {
        super(r1, i1, r2, i2);
    }
    void add() {
        System.out.printf("Addition: %.4f + %.4f i\n", real1 + real2, imag1 + imag2);
    }
    void subtract() {}
    void multiply() {}
    void divide() {}
}

class Subtraction extends Complex {
    Subtraction(double r1, double i1, double r2, double i2) {
        super(r1, i1, r2, i2);
    }
    void subtract() {
        System.out.printf("Subtraction: %.4f + %.4f i\n", real1 - real2, imag1 - imag2);
    }
    void add() {}
    void multiply() {}
    void divide() {}
}

class Multiplication extends Complex {
    Multiplication(double r1, double i1, double r2, double i2) {
        super(r1, i1, r2, i2);
    }
    void multiply() {
        System.out.printf("Multiplication: %.4f + %.4f i\n", real1 * real2 - imag1 * imag2, real1 * imag2 + imag1 * real2);
    }
    void add() {}
    void subtract() {}
    void divide() {}
}

class Division extends Complex {
    Division(double r1, double i1, double r2, double i2) {
        super(r1, i1, r2, i2);
    }
    void divide() {
        double denom = real2 * real2 + imag2 * imag2;
        System.out.printf("Division: %.4f + %.4f i\n", (real1 * real2 + imag1 * imag2) / denom, (imag1 * real2 - real1 * imag2) / denom);
    }
    void add() {}
    void subtract() {}
    void multiply() {}
}

public class Main {
    public static void main(String[] args) {
        double r1 = 2, i1 = 6, r2 = 4, i2 = 2;
        new Addition(r1, i1, r2, i2).add();
        new Subtraction(r1, i1, r2, i2).subtract();
        new Multiplication(r1, i1, r2, i2).multiply();
        new Division(r1, i1, r2, i2).divide();
    }
}

This program creates an abstract class Complex with four instance variables representing the real and imaginary parts of two complex numbers. Four child classes Addition, Subtraction, Multiplication, and Division extend Complex and implement the abstract methods add(), subtract(), multiply(), and divide(), respectively. In the main() method, instances of these classes are created and the corresponding methods are called to perform the operations.
