Watch Dir For New File

Question

I'm trying to monitor a directory on my linux server to watch for new files being created. So far I have this.
watched = new File(inputDirectory);
          long lastModified = watched.lastModified();
          while( true ) {
              if (watched.lastModified() > lastModified) {
              Thread.sleep(2000);
          }If a directory has been created within inputDirectory, I want to move into that file and read some of it's contents. How would I get the name of the directory that was created?

Answer 1

In my project I need to know when only file is created other events are not important for me.Here a code that only trace if file is created on given directory and say what file is created. However I could not totally control every situation but it seems to work .
public class Main {
public static File CurrentFile=new File("");
public static File bestLast=new File("");
public static int currentNumber=0;
public static void main(String[] args) throws InterruptedException {  
File watched = new File("C:\\deneme");
File[] mycurrentFiless= watched.listFiles();
currentNumber=mycurrentFiless.length;
     long lastModified = watched.lastModified();
while(true){
while( true ) {
          if (watched.lastModified() > lastModified)
File[] mycurrentFiles= watched.listFiles();
if(mycurrentFiles.length > currentNumber)
currentNumber=mycurrentFiles.length;
for(int i=0;i<mycurrentFiles.length;i++)
if(mycurrentFiles.lastModified()>bestLast.lastModified())
bestLast=mycurrentFiles[i];
if(CurrentFile!=bestLast)
CurrentFile=bestLast;
System.out.println("hey, New file is created...: FileName is ..:"+bestLast.getName());
break;
}else if(mycurrentFiles.length != currentNumber)
currentNumber=mycurrentFiles.length;
          Thread.sleep(1000);
