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?
