1、 实验内容
1) 设计一个Point类，该类包含两个int类型的成员变量：x、y，一个Color类型的成员变量mycolor。请给出此类的构造方法，分别是一个不带参数的，一个带两个参数的，一个带三个参数的构造方法。还要给出对应的get方法和t方法，最后重写equals和toString方法。
2) Vector类的使用。要求：编写一个程序，创建Vector类的实例vectorInstance；随机产生[0,100]之间的3个整数，依次插入到vectorInstance中；将字符串“hello world”，插入到vectorInstance的末尾。将字符‘A’，插入到vectorInstance的第一个位置；在显示器上输出vectorInstance中的所有数据。
3) 一个公司，拥有普通员工、行政人员和经理三类员工，全体员工的工资都包括：基本工资、奖金，同时享受医疗保险和劳动保险。行政人员和经理还享受车补；经理还有内部分红。请你为该公司设计一个简单的工资管理程序。
