用于监视文本文件更改的Java代码 [英] Java Code to monitor changes in a text file

问题描述

我需要编写一个java代码来检测对文本文件所做的更改，并且还会在文本文件更改时通知对文本文件所做的更改（例如）如果在文本文件中将单词ABCD更改为BCDA，则我需要通知ABCD已更改为BCDA。你能否告诉我是否可以使用java实现这一点（仅使用开源，无付费或商业工具）

I need to write a java code which detects changes done to a text file and also notify what change was done to the text file when the text file is changed ie) If a word ABCD was changed to BCDA in the text file then i need to be notified that ABCD was changed to BCDA. Can you please let me know whether i can achieve this using java(using only opensource and no paid or commercial tools)
