*クラス名*のシンボルが見つかりません？ Java

Question

どちらのクラスも同じパッケージに入っていますので、なぜ動作しないのか非常に混乱しています。それはnetbeansで動作しますが、私は今Visual Studio Codeを使用しています。コードとエラーが表示されます。

（mainメソッドを含む）分割クラス（コンパイル時に認識することができない）

package project; 

import java.util.ArrayList; 
import java.util.Scanner; 


public class Division 
{ 
    public static Scanner scanner = new Scanner(System.in); 

    public static void main(String[] args) 
    { 


     ArrayList<Fighter> fighters = new ArrayList(); 

     fighters.add(new Fighter("Conor McGregor", 29, "Ireland", 21, 3)); 
     fighters.add(new Fighter("Gunnar Nelson", 28, "Iceland", 16, 3)); 
     fighters.add(new Fighter("Stipe Miocic", 33, "USA", 17, 2)); 
     fighters.add(new Fighter("Cody Garbrandt", 26, "USA", 11, 0)); 
     fighters.add(new Fighter("Demetrious Johnson", 30, "USA", 27, 2));

     fighters.add(new Fighter("Fabricio Werdum", 40, "Brazil", 22, 7)); 
     fighters.add(new Fighter("Michael Bisping", 39, "United Kingdom", 30, 7)); 


     displayAllFighters(fighters); 


    }

     } 
    }

Answer 1

まず間違い私は、コンストラクタが必要な体重クラスのパラメータを持っていることがわかりますが、あなたが初期化するときFraireクラスのrraylistには、その値がありません。

例えば、 fighters.add（新しいファイター（ "Conor McGregor"、29、 "Ireland"、21、3））; にはウェイトクラスがありません。
