不正確的輸入

Question

我想寫一些數據到一個文件，這裏是我的代碼：

for (Season s : seasons) { 
      if (s.getYear() >= start && s.getYear() <= end) { 
       line += s.getYear() + ", " + s.getWinTeamName() + ", " 
         + s.getMinorPremiersTeam() + ", " 
         + s.getWoodenSpoonTeam()+ "\n"; } 
} 
System.out.println("File created.\n"); // Informing the user about 
// the creation of the file. 
out.write(line); 
out.close(); 

創建我的文件，但是這是我得到：

2005, Wests Tigers, Parramatta, Newcastle2006, Broncos, Storm, Rabbitohs 

但我想它是：

2005, Wests Tigers, Parramatta, Newcastle 
2006, Broncos, Storm, Rabbitohs 

我認爲在行變量的末尾添加「\ n」會修復，但它沒有。 關於我如何解決這個問題的任何建議？

Answer 1

您需要使用系統特定的換行符分隔符。請參閱System.lineSeparator

Answer 2

如果使用java.io.BufferedWriter，則.newLine()方法將插入相應的行分隔符。

for (Season s : seasons) 
{ 
    if (s.getYear() >= start && s.getYear() <= end) 
    { 
     String line = s.getYear() + ", " + s.getWinTeamName() + ", " 
         + s.getMinorPremiersTeam() + ", " 
         + s.getWoodenSpoonTeam(); 
     out.write(line); 
     out.newLine(); 
    } 
} 

Answer 3

for (Season s : seasons) { 
     if (s.getYear() >= start && s.getYear() <= end) { 
      line += s.getYear() + ", " + s.getWinTeamName() + ", " 
        + s.getMinorPremiersTeam() + ", " 
        + s.getWoodenSpoonTeam()+ "\r\n"; } 
} 

System.out.println("File created.\n"); // Informing the user about 
             // the creation of the file. 
out.write(line); 
out.close();
