包访问和封装。Employee封装类在包路径test3.com.horstmann.corejava下，TestPackageVisitMain类在test3包下，请先写完封装类的3个属性的get方法，然后用后者去访问前者，使得salary增加5%，输出见运行结果。
// Employee.java
package test3.com.horstmann.corejava;
import java.util.*;
public class Employee
{
private String name;
private double salary;
private Date hireDay;
public Employee(String n, double s, int year, int month, int day)
{
name = n;
salary = s;
GregorianCalendar calendar = new GregorianCalendar(year, month - 1, day);
hireDay = calendar.getTime();
}
//待完成——属性的get方法
public void raiseSalary(double byPercent)
{
double raise = salary * byPercent / 100;
salary += raise;
}
}
// TestPackageVisitMain.java
package test3;
import test3.com.horstmann.corejava.*;
import static java.lang.System.*;
public class TestPackageVisitMain
{
public static void main(String[] args)
{
//待完成——访问封装类Employee，输出结果
}
}
/*
程序运行结果：
name=Harry Hacker,salary=52500.0
