/**

• 4、给一个字符串
• name=小红&age=17&salary=8000.00&hireDate=1991-07-03;
• name=小明&age=23&salary=10000.00&hireDate=1992-12-11;
• name=小白&age=18&salary=12000.00&hireDate=1996-01-09，
  请把字符串中的数据封装到 Employee 的对象中，
  类 Employee 有 name（String 类型）、age（int 类型）、salary（薪水是 BigDecimal 类型）、hireDate（入职日期是 Date 类型）
  四个字段且符合 JavaBean 规范
  把三个创建的对象存放数组中，求出在 1996 年前入职的员工的的平均薪资。
