Question: How to check whether there are new text files in a specified folder and what is the date of creation of the text file?

Answer: you can work with the lastmodified timestamp

import java.io.*;
public class T {
public static void main(String[] args) {
File f = new File("test.txt");
long l = f.lastModified();
System.out.println(l);
}
}

Question: I have developed an application. At present the application is in English Language. Now I need to convert this site to another languages but don't know how to do it.
Can anybody tell me the way to do it... I do not want to rewrite every time my code...

Part 2.

The following is a very simple example of a ResourceBundle subclass, MyResources, that manages two resources (for a larger number of resources you would probably use a Hashtable). Notice that you don't need to supply a value if a "parent-level" ResourceBundle handles the same key with the same value (as for the okKey below).

Example:

// default (English language, United States)
public class MyResources extends ResourceBundle {
public Object handleGetObject(String key) {
if (key.equals("okKey")) return "Ok";
if (key.equals("cancelKey")) return "Cancel";
return null;
}
}

// German language
public class MyResources_de extends MyResources {
public Object handleGetObject(String key) {
// don't need okKey, since parent level handles it.
if (key.equals("cancelKey")) return "Abbrechen";
return null;
}
}

You do not have to restrict yourself to using a single family of ResourceBundles. For example, you could have a set of bundles for exception messages, ExceptionResources (ExceptionResources_fr, ExceptionResources_de, ...), and one for widgets, WidgetResource (WidgetResources_fr, WidgetResources_de, ...); breaking up the resources however you like.

This tip is based on API description.
