How to monitor a file?

This should help ....

class FileChangeEventManager extends Thread

{

List<FileChangeEventListener> lst = new ArrayList<FileChangeEventListener>();

List<String> lstFiles = new ArrayList<String>();

public void fileToMonitor(String file)

{

lstFiles.add(file);

}

public void addListener()

{

// add to list

}

public void removeListener()

{

// add to list

}

public void run()

{

while(true)

{

try

{

Thread.sleep(2000);

}

catch(InterruptedException e)

{

}

// if filechanged

{

/*

* 1. create file change event object

* 2. set filename

* 3. loop through all the listener

* 4. inovke filechanged(filechangeevent obj) on all listeners

*/

}

}

}

}

class FileChangeEvent

{

String fileName;

public FileChangeEvent()

{

}

public String getFileName() {

return fileName;

}

public void setFileName(String fileName) {

this.fileName = fileName;

}

}

class FileChangeEventListener

{

public void fileChanged(FileChangeEvent e)

{

}

}

you event listeners should extends FileChangeEventListener to handle events..

enjoy !
