口口聲聲說我必須添加未實現的方法

Question

import java.util.NoSuchElementException; 


/** 
* VolunteerLine Interface represents the interface for the VolunteerLine Class 

* The class that uses this interface uses a Queue of Volunteers to simulate queuing and dequeuing volunteers to and from the 
* VolunteerLine. 
* @author khandan Monshi 
* 
*/ 

public interface VolunteerLineInterface { 

    /** 
    * adds a new Volunteer to the volunteer line Queue 
    * @param v A Volunteer object 
    * @return true if volunteer is queued successfully , false if queue is full 
    */ 
    public boolean addNewVoluneer(Volunteer v); 

    /** 
    * removes volunteer from the volunteer queue line 
    * @return Volunteer Object 
    * @throws NoSuchElementException if queue is empty 
    */ 
    public Volunteer volunteerTurn() throws NoSuchElementException; 

    /** 
    * checks if there are volunteers in line 
    * @return true if volunteer line is empty, true otherwise 
    */ 
    public boolean volunteerLineEmpty(); 
    /** 
    * Returns an array of the Volunteers in the queue 
    * @return an array of the volunteers in the queue 
    */ 
    public Volunteer[] toArrayVolunteer(); 

}

import java.util.NoSuchElementException; 

public class VolunteerLine implements VolunteerLineInterface{ 




    @Override 
    public boolean addNewVoluneer(Volunteer v) { 
     // TODO Auto-generated method stub 

      return false; 


    } 

    @Override 
    public Volunteer volunteerTurn() throws NoSuchElementException { 
     // TODO Auto-generated method stub 
     return null; 
    } 

    @Override 
    public boolean volunteerLineEmpty() { 
     // TODO Auto-generated method stub 

      return false;  

    } 

    @Override 
    public Volunteer[] toArrayVolunteer() { 
     // TODO Auto-generated method stub 

    } 

} 

我不是這個做的是，我還有其他的錯誤，我需要解決，但我遇到的問題是我不斷收到一個錯誤說：「類型VolunteerLine必須實現繼承的抽象方法VolunteerLineInterface.addNewVoluneer（志願者）」即使我明確已經實施。我在VolunteerLine上有一個錯誤，當我將鼠標懸停在它上面並單擊添加未實現的方法時，它仍然顯示出相同的錯誤。有什麼我做錯了嗎？

只需修復其他編譯錯誤並執行清理構建。您發佈的抽象方法的實現很好。
