Java Programing Example to Add Two Complex Numbers by Passing Class to a Function-DevsEnv

Define ComplexNumber Class:

• Create a class named ComplexNumber to represent complex numbers.
• Include real and imaginary parts as instance variables.
• Provide a constructor to initialize the complex number.

class ComplexNumber {
    double real;
    double imaginary;

    // Constructor to initialize the complex number
    public ComplexNumber(double real, double imaginary) {
        this.real = real;
        this.imaginary = imaginary;
    }
}

2. Create a Function for Addition:

   • Create a function, e.g., addComplexNumbers, that takes two ComplexNumber objects as parameters and returns a new ComplexNumber object representing their sum.
   • Calculate the sum of the real and imaginary parts separately.

   class ComplexOperations {
       // Function to add two complex numbers
       public static ComplexNumber addComplexNumbers(ComplexNumber num1, ComplexNumber num2) {
           double realSum = num1.real + num2.real;
           double imaginarySum = num1.imaginary + num2.imaginary;
   
           // Create a new complex number representing the sum
           ComplexNumber sum = new ComplexNumber(realSum, imaginarySum);
           return sum;
       }
   }

4. Test the Program:

   • In your main program, create instances of ComplexNumber representing the two complex numbers you want to add.
   • Call the addComplexNumbers function with these instances and print the result.

   public class ComplexNumberAddition {
       public static void main(String[] args) {
           // Create complex numbers
           ComplexNumber num1 = new ComplexNumber(3.5, 2.0);
           ComplexNumber num2 = new ComplexNumber(1.5, 4.5);
   
           // Add complex numbers
           ComplexNumber sum = ComplexOperations.addComplexNumbers(num1, num2);
   
           // Print the result
           System.out.println("Sum: " + sum.real + " + " + sum.imaginary + "i");
       }
   }

5.  

6. Run the Program:

   • Compile and run the program to see the result of adding the two complex numbers.
