1次元配列に格納されたオブジェクトの特定の文字列を印刷する

Question

Arrayインデックスに格納されているTokenオブジェクトのString名を出力しようとしています。私が得るのは、おそらく場所アドレスのように見えるトークン@です。私はそれがそのオブジェクトの文字列を印刷したい。

int numPlayers = 0; 

    do 
    { 
    System.out.println("Enter the number of players between 2 and 6: "); 

    numPlayers = scan.nextInt(); 
    } 
    while(numPlayers < 2 || numPlayers > 6); 

    Token a = new Token("Battle Ship", 0, 1500, 0); 
    Token b = new Token("Top Hat", 0, 1500, 0); 
    Token c = new Token("Dog", 0, 1500, 0); 
    Token d = new Token("Boot", 0, 1500, 0); 
    Token e = new Token("Wheel Barrow", 0, 1500, 0); 
    Token f = new Token("Race Car", 0, 1500, 0); 
    Token g = new Token("Thinble", 0, 1500, 0); 
    Token h = new Token("Cat", 0, 1500, 0); 

    a.t=1; 
    b.t=2; 
    c.t=3; 
    d.t=4; 
    e.t=5; 
    f.t=6; 
    g.t=7; 
    h.t=8; 

    Token[] PlayerArray = new Token[numPlayers]; // Creates an array to store player objects 

    for(int i = 1; i <= numPlayers; i++) // loop to for players to chose a token 
    { 
     System.out.println("Enter (1) for Battle Ship"); 
     System.out.println("Enter (2) for Top Hat"); 
     System.out.println("Enter (3) for Dog"); 
     System.out.println("Enter (4) for Boot"); 
     System.out.println("Enter (5) for Wheel Barrow"); 
     System.out.println("Enter (6) for Race Car"); 
     System.out.println("Enter (7) for Thimble"); 
     System.out.println("Enter (8) for Cat"); 

      System.out.println(); 
      System.out.println("Player " + i + " Pick a token: "); 
      int userChoice = scan.nextInt(); 

      if(userChoice == 1) 
      { 
       System.out.println("You Picked: " + a.toString()); // 
       PlayerArray[i-1] = a; 
      } 

      else if(userChoice ==2) 
      { 
       System.out.println("You Picked: " + b.toString()); 
       PlayerArray[i-1] = b; 
      } 

      else if(userChoice == 3) 
      { 
       System.out.println("You Picked: " + c.toString()); 
       PlayerArray[i-1] = c; 
      } 

      else if(userChoice == 4) 
      { 
       System.out.println("You Picked: " + d.toString()); 
       PlayerArray[i-1] = d; 
      } 

      else if(userChoice == 5) 
      { 
       System.out.println("You Picked: " + e.toString()); 
       PlayerArray[i-1] = e; 
      } 

      else if(userChoice == 6) 
      { 
       System.out.println("You Picked: " + f.toString()); 
       PlayerArray[i-1] = f; 
      } 

      else if(userChoice == 7) 
      { 
       System.out.println("You Picked: " + g.toString()); 
       PlayerArray[i-1] = g; 
      } 

      else if(userChoice == 8) 
      { 
       System.out.println("You Picked: " + h.toString()); 
       PlayerArray[i-1] = h; 
      } 

      System.out.println(); 

    } 

私は自分自身の謎を解く...

このソリューションは、選手だけの量にbassedサイズの配列を作成し、配列にプレーヤーを格納します。最初にオブジェクトを作成した後、そのオブジェクトが配列に格納されているユーザーによって選択されます。オブジェクトには、ユーザーが選択する値が割り当てられます。クラス内で作成したメソッドから、そのユーザーに属する値を取得できます。
