no sé como debo llamar a esos metodos y realizar sus operaciones.
gracias
Código PHP:
public final class Complex {
private final double re;
private final double im;
public Complex(double re, double im) {
this.re = re;
this.im = im;
}
// Accessors with no corresponding mutators
public double realPart() { return re; }
public double imaginaryPart() { return im; }
public Complex add(Complex c) {
return new Complex(re + c.re, im + c.im);
}
public Complex subtract(Complex c) {
return new Complex(re - c.re, im - c.im);
}
public Complex multiply(Complex c) {
return new Complex(re * c.re - im * c.im,
re * c.im + im * c.re);
}
public Complex divide(Complex c) {
double tmp = c.re * c.re + c.im * c.im;
return new Complex((re * c.re + im * c.im) / tmp,
(im * c.re - re * c.im) / tmp);
}
@Override public boolean equals(Object o) {
if (o == this)
return true;
if (!(o instanceof Complex))
return false;
Complex c = (Complex) o;
// See page 43 to find out why we use compare instead of ==
return Double.compare(re, c.re) == 0 &&
Double.compare(im, c.im) == 0;
}
@Override public int hashCode() {
int result = 17 + hashDouble(re);
result = 31 * result + hashDouble(im);
return result;
}
private int hashDouble(double val) {
long longBits = Double.doubleToLongBits(re);
return (int) (longBits ^ (longBits >>> 32));
}
@Override public String toString() {
return "(" + re + " + " + im + "i)";
}
public static void main(String arguments[])
{
Complex complejo = new Complex(5,6);
System.out.println("Resultado:"+complejo);
}
}
