今天是挂科指南第二次更新java，希望我的安卓能好好的下去，根据《Java核心技术 卷1 基础知识》敲了一下雇员类，代码如下：

package com.company;
import java.time.DayOfWeek;
import java.time.LocalDate;
import java.util.*;
public class Main {
    public static void main(String[] args){
        Employee[] staff = new Employee[3];

        staff[0] = new Employee("Carl Cracker",75000,1987,12,15);
        staff[1] = new Employee("niuu kexue",75000,1987,12,15);
        staff[2] = new Employee("zhang zhi",75000,1987,12,15);
        for (Employee e : staff) {
            e.raiseSalary(5);
            System.out.println("name=" + e.getName()
            + ",salary=" + e.getSalary()
            + ",hireDay=" + e.getHireDay());
        }
    }

}
class Employee
{
    private String name;
    private double salary;
    private LocalDate hireDay;

    public Employee(String n,double s,int year,int month,int day)
    {
        name = n;
        salary = s;
        hireDay = LocalDate.of(year,month,day);
    }

    public String getName()
    {
        return name;
    }
    public double getSalary()
    {
        return salary;
    }
    public LocalDate getHireDay()
    {
        return hireDay;
    }
    public void raiseSalary(double byPercent)
    {
        double raise = salary * byPercent / 100;
        salary += raise;
    }
}
