public void setImaginary(double imaginary) {

main function：

public class Main{
public static void main(String[] args) {
ComplexNumber c1 = ComplexNumber.min(new ComplexNumber(1, 1), new ComplexNumber(1, -1));
System.out.println(c1.getReal()+"+"+c1.getImaginary()+"i");
ComplexNumber c = ComplexNumber.multiplication(new ComplexNumber(1, 1), new ComplexNumber(1, -1));
System.out.println(c.getReal()+"+"+c.getImaginary()+"i");
}
}
