我有一个运行良好的代码，但它看起来太大了，因为它有重复的代码行，有人能帮我把它缩短吗？

public void writeToFile(String file)
{
    try
    {
            PrintWriter pWrite = new PrintWriter(file);
            pWriter.println("[Auto data]");
            for (Auto line : autoMap.values())
            {
                if (line instanceof Auto)

                    String getLine = line.writeData(file);
                    pWrite.println(getLine);

            }
            pWriter.println();
            pWriter.println("[Sport data]");
            for (Sport line : sportMap.values())

                if (line instanceof Sport) 
                {
                    String getLine = line.writeData(file);
