这是一个 CSE 作业，我希望那里可能有一些友好的男孩和女孩可以快速浏览一下，看看它是否看起来不错，谢谢大家。
这是我写的说明和代码，

编写一个 ComplexNumber 类：
(1) 不带任何参数的构造函数（在这种情况下，复数的默认值应为 0 + 0i。）
(2) 另一个将 int 类型的实部和虚部作为参数的构造函数
(3) add 方法，它以另一个复数 c2 作为参数并将 c2 与当前复数相加，即 this，并返回结果复数。(4) 以另一个复数 c2 作为参数并从当前复数 this 中减去 c2 的减法方法，并返回结果复数。
(5) 以另一个复数 c2 作为参数并将 c2 与当前复数 this 相乘的乘法方法，并返回结果复数。
(6) 除法，它以另一个复数 c2 作为参数，将当前复数除以 c2，并返回结果复数。
(7) 一个 toString1 方法，它将以 a + bi 的形式打印一个作为当前复数的字符串，其中 a 和 b 将是自然数的实部和虚部的值。
