Example: Add Two Complex Numbers
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);
}
}
Output
Sum = 5.7 + 9.5i
In the above program, we created a class Complex
with two member variables: real and imag. As name suggests, real stores real part of a complex number and imag stores the imaginary part.
The Complex
class has a constructor with initializes the value of real and imag.
We also created a new static function add()
that takes two complex numbers as parameters and returns the result as a complex number.
Inside the add()
method, we just add the real and imaginary parts of complex numbers n1 and n2, store it in a new variable temp and return temp.
Then, in the calling function main()
, we print it using printf()
function.
