Dans ce programme, vous apprendrez à additionner deux nombres complexes en créant une classe nommée Complex et en la passant à la fonction add().
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); } }
When running the program, the output is:
Sum = 5.7 + 9.5i
In the above program, we created a Complex class with two member variables: real and imag. As the name implies, real stores the real part of the complex number, and imag stores the imaginary part.
The Complex class has a constructor that initializes the values of real and imag.
We also created a new static function add(), which takes two complex numbers as parameters and returns the result as a complex number.
Inside the add() method, we only add the complex number n1and n2the real and imaginary parts are added together, stored in the new variable temp, and returned as temp
Then, in the call to the function main(), we use the printf() function to print.
