Question

Make a program in Java language that performs Addition, Subtraction and Multiplication of two complex numbers
-There should be a menu
-The operations must be functions and/or procedures that must be called in the main program

Expert Solution

Program Approach

The steps to create the program are mentioned below.

Create a class menu to define the complex numbers and the operations to be performed on them.
- Create two float variables to hold the real and imaginary values.
- Create a parameterized constructor to initialize the object of the class with the parameters passed to it.
- Define method disp to display the complex number equation.
- Define the add method to add the two complex numbers by adding the real and imaginary parts separately.
- Define the sub method to add the two complex numbers by subtracting the real and imaginary parts separately.
- Define the mul method to add the two complex numbers by multiplying the real and imaginary parts separately.
Create public myClass to implement complex number operations using the main method.
- Create two complex numbers using the object of the menu class.
- Display the menu with the addition, subtraction, and multiplication operations.
- Use a do-while loop to continue with the operations if the user wishes to.
- Input the choice of operation from the user and use it in the switch statement.
- Call the respective methods and display the result for each case of choice.
- Ask the user if they wish to continue and take input in the variable cont.
