**Write a Java Program to Add Two Complex Numbers by Passing Class to a Function**

public class Complex {
double real;
double imag;
public Complex(double real, double imag) {
this.real = real;
this.imag = imag;
}
public static void main(String[] args) {
Complex n1 = new Complex(2.3, 4.5),
n2 = new Complex(3.4, 5.0),
temp;
temp = add(n1, n2);
System.out.printf("Sum = %.1f + %.1fi", temp.real, temp.imag);
}
public static Complex add(Complex n1, Complex n2)
{
Complex temp = new Complex(0.0, 0.0);
temp.real = n1.real + n2.real;
temp.imag = n1.imag + n2.imag;
return(temp);
}
}

**Final output**
