JAVA: Complex numbers Program

This is giving me a hard time... very difficult to try to imagine and even execute after laying it out with pseudocode/diagram

Would appreciate any help please!

A complex number is a number of the form a+ real numbers and i is V real part and imaginary part of the complex number, respectively. You can perform addition, subtraction, multiplication, and division for complex numbers using the following formula: bi, where a and b are The numbers a and b are known as the a +bi+c+di (a +c)+(b+d)i a +bi -(c+di) (a-c)+(b-d)i (a+bi)*(c+di)-(ac-bd) +(bc +ad)i (a + bi)/(c+ di) (ac+bd)/(c +d2)+ (bc-ad)i l(c+d2) You can also obtain the absolute value for a complex number using the following formula: (A complex number can be interpreted as a point on a plane by identifying the (a,b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in Figure 13.12b.) Design a class named Complex for representing complex numbers and the methods add, subtract, multiply, divide, 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 bis 0, it simply returns a. 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 getReal Part and getImaginaryPart methods for returning the real and imaginary part of the complex number, respectively
