String path = "c:/test";int mask =  JNotify.FILE_CREATED | JNotify.FILE_DELETED | JNotify.FILE_MODIFIED| JNotify.FILE_RENAMED;boolean watchSubtree = true;int watchID = JNotify.addWatch(path, mask, watchSubtree, new JNotifyListener(){public void fileRenamed(int wd, String rootPath, String oldName, String newName){System.out.println("JNotifyTest.fileRenamed() : wd #" + wd + " root = " + rootPath + ", " + oldName + " -> " + newName);}public void fileModified(int wd, String rootPath, String name){System.out.println("JNotifyTest.fileModified() : wd #" + wd + " root = " + rootPath + ", " + name);}public void fileDeleted(int wd, String rootPath, String name){System.out.println("JNotifyTest.fileDeleted() : wd #" + wd + " root = " + rootPath+ ", " + name);}public void fileCreated(int wd, String rootPath, String name){System.out.println("JNotifyTest.fileCreated() : wd #" + wd + " root = " + rootPath+ ", " + name);}});// to remove watch:boolean res = JNotify.removeWatch(watchID);if (!res){// invalid watch ID specified.}

硬盘监控在很多场合都很有用处，例如在线文档转换，只要监控到有文件写入，即可触发在线文档转换程序。JNotify支持windows和Linux两大操作系统，并且支持64位的机器，在使用JNotify时，需要手动将JNotify.dll或者libjnotify.so复制到JRE的bin目录下，然后在你的JAVA工程编写如下代码：
