// 乘和除类似

public static void main(String[] args){
//获得测试用例的参数x，y
//获得方法，我不清楚你说的意思，我自定义一个，不是的话自己修改下
int x1=1;
int y1=2;
int x2 =5;
int y2=9;
Complex a1 = new Complex(x1,y1);
Complex a2 = new Complex(x2,y2);

Complex result1 = addComp(a1,a2);
showComp(result1);

Complex result2 = subComp(a1,a2);
showComp(result2);

//乘法除法类似
}
}
