找不到符號錯誤Netbeans

嗨，我是新來的Java和我正在寫一個簡單的程序，將模擬跳水比賽。我使用NetBeans，我無法找出它爲什麼會給我這個錯誤。的代碼是這樣的：找不到符號錯誤Netbeans

package agoneskataduseon; 
import java.util.Scanner; 

public class AgonesKataduseon { 

public static void main(String[] args) { 
     Scanner input = new Scanner(System.in); 
     int numAth, numJud, numDiv; 
     System.out.print("Give the number of the athletes in the competition : "); 
     numAth = input.nextInt(); 
     System.out.print("Give the number of the judges : "); 
     numJud = input.nextInt(); 
     System.out.print("Give the numbe rof dives : "); 
     numDiv = input.nextInt(); 
     DivingCompetition game = new Diving Competition(numAth, numJud, numDiv); 
    } 
}

的DivingCompetition類（未完成它）：

import java.util.Scanner; 
public class DivingCompetition { 
    int numa; 
    int numj; 
    int numd; 
    Athlete[] arr1 = new Athlete[12]; 
    Athlete[] arr2 = new Athlete[12]; 

    public DivingCompetition(int numAthletes, int numJudges, int numDives){ 
     numa = numAthletes; 
     numj = numJudges; 
     numd = numDives; 
    } 

    public void readAthletesName(){ 
     String nam; 
     int i=0; 
     Scanner input = new Scanner(System.in); 
     while(i < numa){ 
      System.out.print("Give the name of athlete num "+(i+1)+" : "); 
      nam = input.nextLine(); 
      arr1[i] = new Athlete(nam); 
      i++; 
     } 
    } 

    public void runCompetition(){ 
     int i=0; 
     Dive dv = new Dive(numj); 
     while(i<12){ 
      arr1[i].addDive(dv); 
     } 
    } 
}

並記錄在案運動員等級：

public class Athlete { 
     String names; 
     Dive[] arrayd = new Dive[6]; 
     double fullScore; 
     int point; 

    public Athlete(String name){ 
     names = name; 
     fullScore = 0; 
     point = 0; 
    } 

    public void addDive(Dive dive){ 
     arrayd[point] = dive; 
     fullScore = fullScore + arrayd[point].computeScore(); 
     point++; 
    } 
}

我也給你潛水類，但我沒有看到這樣做的要點

NetBeans是givi納克我的錯誤主要功能：找不到符號符號：類DivingCompetition 位置：類AgonesKataduseon

我的問題是，爲什麼它給了我這個錯誤？這個問題也會發生，如果我試圖使主體功能內的運動員或潛水的對象

我認爲你必須導入這個類。嘗試'Ctrl-Shift-I'。來源：https：//netbeans.org/project_downloads/usersguide/shortcuts-80.pdf – markspace

因爲'DivingCompetition'不在同一個包中。 –

我嘗試了Ctrl-Shift-I方法，但它沒有在導入語句中修復。你能給我提供另一種解決方案嗎？我是新來的NetBeans，我沒有用它如何工作 –
