2020,12.13 实现人员信息的录入，以及给定找出符合提薪要求人员的方法，找出优秀员工的方法

import java.util.Date;

public class Employee {
private String name;

    return name;
}

}

    this.birthDay = birthDay;
}

    return hireDate;
}

public void setHireDate(Date hireDate) {
    this.hireDate = hireDate;
}

public int getWorkingHours() {
    return workingHours;
}

public void setWorkingHours(int workingHours) {
    this.workingHours = workingHours;
}

@Override
public String toString() {
    return "Employee{" +
            "name='" + name + '\'' +
            ", department='" + department + '\'' +

}
public Employee(String name,String department,Date birthDay,Date hireDate){
    this.name=name;
    this.department=department;
    this.birthDay=birthDay;

}
制造三个方法，第一个方法插入员工信息，第二个方法找出符合二级涨薪的条件，第三个方法找出符合优秀员工奖的员工。

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;

public class Hello {
public static void main(String[] args) throws Exception{
EmployeeManagerSupport2 empn=new EmployeeManagerSupport2();
try{
List emps=empn.findEmp(80);
System.out.println(“以下员工提薪两级”);
for (Object temp:emps){
System.out.println(temp.toString());
}
}catch (Exception e){
e.printStackTrace();
}
try{
Date date=new SimpleDateFormat(“yyyy-MM-dd”).parse(“1978-11-18”);
List emp5=empn.findEmp(date);
System.out.println(“以下员工为突出贡献奖”);
for (Object temp:emp5){
System.out.println(temp.toString());
}
}catch(Exception e){
e.printStackTrace();
}
}
}

//测试。
