從java中讀取文件，但輸出會跳過其他所有行

我正在嘗試讀取文件並以特定格式打印出結果。打印時，它只打印每一個其他條目。在while循環中，我嘗試切換if語句並將0更改爲-1，然後對++進行計數，但無效。從java中讀取文件，但輸出會跳過其他所有行

try 
    { 
    File f = new File("BaseballNames1.csv"); 
    FileReader fr = new FileReader(f); 
    BufferedReader br = new BufferedReader(fr); 

    ArrayList<String> players = new ArrayList<String>(); 
    String line; 
    int count = 0; 

    while((line = br.readLine()) != null) 
    { 
     if(count == 0) 
     { 
      count++; 
      continue; 
     } 
     players.add(br.readLine()); 
    } 

    for(String p : players) 
    { 
     String[] player = new String[7]; 
     player = p.split(","); 

     first = player[0].trim(); 
     last = player[1].trim(); 
     birthDay = Integer.parseInt(player[2].trim()); 
     birthMonth = Integer.parseInt(player[3].trim()); 
     birthYear = Integer.parseInt(player[4].trim()); 
     weight = Integer.parseInt(player[5].trim()); 
     height = Double.parseDouble(player[6].trim()); 
     name = first + " " + last; 
     birthday = birthMonth + "/" + birthDay + "/" + birthYear; 
     System.out.println(name + "\t" + birthday + "\t" + weight + "\t" + height); 
     //System.out.printf("First & Last Name %3s Birthdate %3s Weight %3s Height\n", name, birthday, weight, height); 
    } 
    } 
    catch(Exception e) 
    { 
    e.getMessage(); 
    }

在添加剛剛閱讀的行之前，您要調用br.readLine（）兩次。所以它應該是players.add（線）; – Juniar 2014-09-27 15:50:14

我覺得你的問題就在這裏：

while((line = br.readLine()) != null) 
{ 
    if(count == 0) 
    { 
     count++; 
     continue; 
    } 
    players.add(br.readLine()); 
}

你正在閱讀一個新行每一次，即使您已經閱讀之一。你想這樣的：

while((line = br.readLine()) != null) 
{ 
    if(count == 0) 
    { 
     count++; 
     continue; 
    } 
    players.add(line); //The important change is here. 
}

啊啊謝謝@ Pokechu22！ – 2014-09-27 17:16:21

變化

players.add(br.readLine());

到

players.add(line);

您的版本讀取和寫入下一行players，不是當前。
