这就是它所写的，最后当我尝试打印文件中的内容时，我得到的只是 NewFile.txt，而不是文件中实际的内容，有人可以帮忙吗？

        String origFileName = "zuess.RTF";

        //Name of new file

试试这个方法:

public static void main (String args[]) throws IOException {

    //Get the system defined
    String newLine = System.getProperty("line.separator");

    //Name of original file
    String origFileName = "new.txt";

    //Name of new file
    String newFileName = "NewFile.txt";

    //Creating the PrintWriter
    PrintWriter outputStream = null;
    try {
        outputStream = new PrintWriter
                (new File(newFileName));
    } catch (FileNotFoundException e1) {
        System.out.println("Error opening the file " + origFileName);
        System.exit(0);
    }

    //Opening origin file and getting all lines
    Path pathA = Paths.get(origFileName);
    List<String> file = Files.readAllLines(pathA);

    //for every line from origin file
    for ( String line: file) {

        //split line to get words
        String[] arr = line.split(" ");
        for(int i = 1; i < arr.length; i++)
        {
            //So the data will print in the new file
            outputStream.write(arr[i] + " ");
        }
        //Line separator
        outputStream.write(newLine);
    }
    //Close Stream
    outputStream.close();

}
