Java-集合(List)编程︰创建一个工人类，属性︰姓名、年龄、工资，要求如下︰_创建一个集合储存员工信息,员工信息包括工号、姓名、年龄、工资等。要求员工信息

创建一个工人类，属性︰姓名、年龄、工资，要求如下︰
(1)为Worker提供无、有参数的构造方法，属性私有，并提供公开的get/set(2)创建多个Worker类，存储在List集合中。
(3)打印输出所有的工人信息。
(4)计算所有工人的平均工资。
(5)打印输出姓名中包含"胡”的所有工人信息。
(6)打印输出所有姓"胡”的工人信息。
(7)键盘输入一个姓名，查找是否存在此员工，存在，则打印输出员工的信息，如果不存在，则输出"查无此人"
(8输入一个工资，查询工资大于输入工资的员工信息。
