我写的代码但是编译时出错了 请高手给看看代码如下：
import java.util.*;
public class EmployeeSortTest {
public static void main(String[] args) {
    Employee [] staff=new Employee[3];
    staff[0]=new Employee("Harry Hacker",35000);
    staff[1]=new Employee("Carl Cracker",75000);
    staff[2]=new Employee("Tony Tester",35000);
    Arrays.sort(staff);
    for(Employee e :staff){
        System.out.println("name="+e.getName()+",salary="+e.getSalary());
    }
}
}

class Employee implements Comparable<Employee>{

    public Employee(String n, double s){
        name=n;
        salary=s;
    }
    public String getName(){
        return name;
    }
    public double getSalary(){
        return salary;
    }
    public void raiseSalary(double byPercent){
        double raise=salary*byPercent/100;
        salary+=raise;
    }
    public int compareTo(Employee other) {
    if(salary<other.salary)return -1;
    if(salary>other.salary)return 1;
        return 0;
    }
   
    private String name;
    private double salary;
}
编译运行时提示：
Exception in thread "main" java.lang.NoSuchMethodError: Employee.<init>(Ljava/lang/String;D)V
    at EmployeeSortTest.main(EmployeeSortTest.java:5)
求高手给帮忙看看！

但是我的在编译时就提示class Employee implements Comparable<Employee>这句里的Employee有错误！是编译器版本的问题么 我的也是elicpse啊！
