编译错误，求真相

Question

按照书上自己敲的代码，对比了好像没有问题，可就是提示错误，请大大们 明示！import java.util.*;
public class EmployeeTest{
public static void main(String[] args){
Employee[] staff = new Employee[3];

Employee[0] = new Employee("Tom",7500,1983,10,14);
Employee[1] = new Employee("Karl",6500,1986,8,14);
Employee[2] = new Employee("Jak",5500,1989,10,10);

for(Employee e: staff)
e.riseSalary(5);

for(Employee e: staff)
System.out.println("name:"+e.getName()+" salary: "+e.getSalary()+"hireDay:  "+ e.getHirday());
}
}

 class Employee{
private String name;
private double salary;
private Date hireDay;

public Employee(String s,double salary,int year,int month,int day){
name = s;
this.salary =  salary;
//
GregorianCalendar g = new GregorianCalendar(year,month,day);
hireDay = g.getTime();
}

salary+=risepart;
}

Answer 1

         Employee[] staff = new Employee[3];
        
        Employee[0] = new Employee("Tom",7500,1983,10,14);//改为staff[0]
