properties檔案是以鍵值對的形式存放的

如果出現中文亂碼的問題，那麼就得加上字符集、

如果後面你還要對properties檔案進行其他操作，比如刪除file.delete()，那麼就得關閉io，解除對properties檔案的呼叫，不然這個檔案會刪除失敗

FileInputStream fIn = new FileInputStream("D:/Develop/2.properties");
Properties properties = new Properties();
properties.load(new InputStreamReader(new BufferedInputStream(fIn), "utf-8"));
fIn.close();//將流關閉
