Java编写异常类练习

1.编写异常类：空异常、年龄低异常、年龄高异常、 工资低异常、工资高异常、身份证非法异常。
2.编写一个员工类:
(1)属性： 编号、姓名、年龄、工资、身份证号码、员工人数）、员工工资总额。
(2)构造器：
构造器1：设置编号、年龄、姓名，如果年龄小于18，抛出年龄低异常；如果年龄大于60，抛出年龄高异常；如果姓名为null或为空字符串，抛出空异常。
构造器2：设置工资、设置身份证号码，如果工资低于600，抛出工资低异常； 如果身份证不是18位，抛出身份证非法异常。
(3)方法
增加工资 addSalary(double addSalary)，抛出工资高异常，当增加后的工资大于员工工资总额时，抛出此异常。
减少工资 minusSalary(double minusSalary)，抛出工资低异常，当减少后的工资低于政府最低工资时，抛出工资低异常。
显示员工工资总额方法：showTotalSalary()，抛出空异常，当工资总额为0时，抛出此异常。
显示员工人数：showTotalEmployee()，抛出空异常，当员工人数为0时，抛出此异常 。
3.编写main主测试类。

public class HighAgeException extends Exception  {
	public HighAgeException() {

	}
