9333,12,120,2,1 
PRINT 
9533,5,45,0,0 
8573,10,120,1,0

        Integer playerOne = one.player_ID; 
        Integer playerTwo = two.player_ID; 

        return playerTwo.compareTo(playerOne); 
       } 
       Integer scoreOne = one.total_score; 
        Integer scoreTwo = two.total_score; 

       return scoreTwo.compareTo(scoreOne); 
       } 
     }); 
     System.out.println("Ordered"); 
     for (FantasyPlayers str : Stats) 
     { 
      System.out.println(str); 
     } 

    } 

} 

我不斷收到錯誤ArrayIndexOutOfBoundsException異常：1在int score =位置。

我的問題是我如何處理代碼中的PRINT語句......我能夠對數據做我想做的事情，但我需要邏輯在讀取print語句時執行某些操作。有什麼建議麼？

Answer 1

你，我的朋友已經愛上了最常見的Java錯誤....

試試這個

if (!line.equalsIgnoreCase("PRINT")) 

Answer 2

試圖改變這一行

String delims = "[,]"; 

到

String delims = ","; 

這行

line != "PRINT" 

到

!line.trim().equals("PRINT")
