用java编译一个复数Complex程序,满足以下条件：（越快越好,
1）、复数类Complex的属性有：
realPart:int型,代表复数的实数部分.
imaginPart:int型,代表复数的虚数部分.
2）、复数类Complex的方法有：
Complex（）：构造函数,将复数的实数和虚数部分都置为0.
Complex（int r,int i）构造函数,形参r为实部的初值,i为虚部的初值.
Complex complexAdd（Complex a）:将当前复数对象与形参复数对象相加,所得的结果仍为一个负数值,返回给此方法的调用者.
String toString()：把当前复数对象的实部、虚部组合成a+bi的字符串形式,其中a和bi分别为实部和虚部的数据.
3）、编写测试类Test,在其主方法测试1+2i和3+4i相加产生一个新的复数4+6i,并输出结果.
