compare 2 coloum of 2 diff files using perl script

Hi,

i am new to perl scripting.. i am still learing it.. i am asked to write a perl script which should compare 2 coloums of 2 different files. if those 2 coloumn are same the script should store the both the lines in 2 diff files.

these are files,

file 1:
21767016 226112 char[]
19136520 797355 java.lang.String
17769368 307049 java.lang.Object[]
13981656 582569 java.util.HashMap$Entry
10867240 16650 int[]
9065616 559799 java.lang.String[]
9060192 79626 java.util.HashMap$Entry[]
6969384 23146 byte[]
6857664 285736 java.util.Vector

file 2:
21702192 904258 java.lang.String
20985320 360561 java.lang.Object[]
20524112 209810 char[]
12623280 525970 java.util.HashMap$Entry
10945080 678896 java.lang.String[]
9781432 10871 int[]
8302464 345936 java.util.Vector
8107104 337796 netscape.ldap.util.RDN
7620024 68357 java.util.HashMap$Entry[]
6515152 52272 * ConstMethodKlass

so i have to compare 3rd coloumn of these to 2 files, eg i have java.lang.string present in both so i want the script store these complete line of both the files in 2 diff files. These 2 files are big files.

please suggest me how can this be done. some one had suggested you can use the hash table implementation.

thanks,
Vasuki

build-lives-rfx-plugin

build-lives-rfx-plugin(1)				      General Commands Manual					 build-lives-rfx-plugin(1)

NAME

       build-lives-rfx-plugin - builds rendered effects for LiVES

SYNOPSIS

       build-lives-rfx-plugin script_name [plugin_dir] -get section file

DESCRIPTION

       This perl script is used by LiVES to compile an RFX (rendered effect) plugin for LiVES. It is generally called from build-lives-rfx-plugin-
       multi for a script which has a language code representing LiVES-perl. The script_name must be  the  full  (absolute)  path  to  the  plugin
       script,	and  plugin_dir  can  be  used to specify the output directory where the compiled plugin should be generated. If plugin_dir is not
       defined then /tmp is assumed.

       The second variant with -get is used to print out a script section from a plugin script to stdout. It is generally only used internally	by
       LiVES.

       Return values The script returns the following values

       0 - success 1 - the value of a trigger was greater than the number of parameters 2 - a value could not be read from the script file 3 - the
       language code of the plugin script was not equivalent to LiVES-perl 4 - the API version level of the plugin script  was	invalid  5  -  the
       <define> section was missing from the plugin script
