请问是哪个地方出问题了，一直是这个错误，应该怎么修改

class Employee{
  private String name;
  private int salary;
  public Employee(String name,int salary){
    this.name=name;
    this.salary=salary;
  }
  public String getDtetails(){
    return"Name:"+name+"\nSalary:"+salary;
  }
}
//定义Employee的子类Manager
class Manager extends Employee{
  private String department;
  public Manager(String name,int salary,String department){
    super(name,salary);//调用父类Employee的构造方法
    this.department=department;
  }
  public String getDetails(){
    //调用父类的成员方法
   return super.getDetails()+"\nDepartment:"+department;
  }
}
public class TestSuper{
 public static void main(String[]args){
    Manager m=new Manager("Tom",2000,"Finance");
    System.out.println(m.getDetails());
  }
}
