I havent worked with RE in java but if i was programming in lex and yacc i would have read each filename from the directory and compared it with [_a-zA-Z]+[0-9_a-zA-Z]*\."doc" and if it is valid its a .doc file

If java uses RE the same way you can use it.Actually RE's are used the same way everywhere but wouldnt want to misguide you by saying its the same way in java too.Check out the tutorials

What do you mean by get the filename based upon the extension?Are you trying to filter the listing that you would receive from - say - the JFileChooser?

perhaps you can understand through this illustration

for(all Files)

{

if(extension.equals(".doc");

System.out.println(Filename);

}

Thank you

This might help.The answer according to me lies in RE because i have used it to achieve similar tasks,Read this http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html
