给定正确的文件路径时，createNewFile() 抛出 FileNotFoundException

Question

下面是我的代码：

public void playerNaming() throws IOException {
      Scanner pickName = new Scanner(System.in);
      System.out.println("What do you want your username to be?");
      String playerName = pickName.nextLine();
      userName = playerName;
      File file1 = new File("PlayerFiles\" + playerName + ".txt");
      File file2 = new File(file1.getAbsolutePath());
      System.out.println(file2);
      file2.createNewFile();
      BufferedWriter file3 = new BufferedWriter(new FileWriter(file2));
}

在线file2.createNewFile();它抛出

java.io.FileNotFoundException: (在此插入正确的文件路径)系统找不到指定的路径

怎么了？根据我阅读的所有文章和其他 Whosebug 问题，这应该有效。

检查你的文件路径：

public static void main(String args[]) 
    { 
  
        try { 
  
            // Get the file 
            File f = new File("F:\program1.txt"); 
  
            // Create new file 
            // if it does not exist 
            if (f.createNewFile()) 
                System.out.println("File created"); 
            else
                System.out.println("File already exists"); 
        } 
        catch (Exception e) { 
            System.err.println(e); 
        }

注意：文件“F:\program.txt”是F:目录中的现有文件。
