Alternatively you could use File::Find::Rule

use File::Find::Rule;

my @files = File::Find::Rule->file()
                            ->name('*.java')
                            ->in('your/dir/here');

Which will return a list of all the files with the .java extension in the given directory and all of it's subdirectories.

Hello All,
thanks you so much for all the replies
Here is what i wrote with File::Find


#!/usr/bin/perl
use strict;
use warnings;
use File::Find;


my @java_files;
my $pattern = shift;

if ($pattern eq '') 
{
    print "defaulting the directory to the current one\n";
    $pattern = '.';
}

print "$pattern\n";
find(\&wanted, $pattern);
foreach my $file (@java_files)
{    
    open OUTFILE, "$file";
    while(<OUTFILE>)
    {
        print "$_\n";
    }
}

my $java_files = @java_files;
print "++ Total number of java files in project =  $java_files\n";

sub wanted()
{
    if (/\.java$/i)
    {        
        push(@java_files,  $_);
    }
}

The problem is that the contents of the files are not
getting printed. because the file open is failing.
the file open is failing because I have only the file name
and not the complete path of the file. what can I do go get
the complete file name in my java_file array?

Did you read my reply? You would have noticed I was using $File::Find::name rather than $_ in the sub I pass to find because I anticipated just that problem. :-) See the docs to File::Find for more details.
