Java实现复数运算

else
System.out.println(this.realPart + "+" + this.imagePart + "i");
}
// add two complexes
public void add(Complex x, Complex y) {
this.realPart = x.realPart + y.realPart;
定义一个复数类complex，它的内部具有两个实例变量：realPart和imagPart，分别代表复数的实部和虚部，
编程实现要求的数学运算。
(1)实现两个复数相加。复数加运算的原则是：复数的实部和虚部分别相加。
(2)实现两个复数相减。复数减运算的原则是：复数的实部和虚部分别相减。
(3)输出运算结果，判断是否正确。
