class Empolyee{
    private String name;
    private int salary;
    public Empolyee(String name,int salary){
        this.name = name;
        this.salary = salary;
    }
    public String getDetails(){
        return "Name:"+name+"\nsalary:"+salary;
    }
}
class Manager extends Empolyee{
    private String department;
    public Manager(String name,int salary,String department){
        super(name,salary);
        this.department = department;
    }
    public String getDetails(){
        return super.getDetails()+"\ndepartment:"+department;
    }        
}
public class TestSuper{
    public static void main(String args[]){
        Manager m = new Manager("Tom",2000,"Finace");
        System.out.println(m.getDetails());
    }
}
 manager是不能继承Empolyee中name和salary的，也就是说manager中的属性只有一个：department。但结果为什么却显示了name和salary属性

那么程序中的this指的是Manager还是Empolyee呢？
