为什么这个程序运行后打印的名字和薪水的值为空呢?
import java.util.*;public class EmployeeTest
{
public static void main(String[] args)
{
Employee[] staff = new Employee[3];
staff[0] = new Employee("张三",75000,1987,12,15){};
staff[1] = new Employee("李四",50000,1989,10,1){};
staff[2] = new Employee("王五",40000,1990,3,15){};
for(Employee e:staff)
e.raiseSalary(5);
for(Employee e:staff)
System.out.println("name="+e.getName()+",salary="+e.getSalary()+",hireDay="+e.getHireDay());
}
}
class Employee
{
private String name;
private double salary;
private Date hireDay;
public Employee(String n,double s,int year,int month,int day)
{
String name = n;
double salary = s;
GregorianCalendar calendar = new GregorianCalendar(year,month-1,day);
hireDay = calendar.getTime();
}
public String getName()
{
return name;
}
public double getSalary()
{
return salary;
}
public Date getHireDay()
{
return hireDay;
}
public void raiseSalary(double byPercent)
{
double raise = salary*byPercent/100;
salary += raise;
}
}
