Re: how to use inline

[Patrick LeBoutillier]

Gargi,

To do this you will need install Inline::Java. Get it from
CPAN (http://www.cpan.org/modules/by-module/Inline/), along with
its dependencies (Inline, Digest::MD5, Parse::RecDescent).

The Inline::Java documentation caontains a lot of examples on
how to use it, but basically, once you have installed all the
modules, you do something like this:

   use Inline Java => <<'END_OF_JAVA_CODE' ;
      class Pod_alu {
         public Pod_alu(){
         }

         public int add(int i, int j){
            return i + j ;
         }

         public int subtract(int i, int j){
            return i - j ;
         }
      }
   END_OF_JAVA_CODE

   my $alu = new Pod_alu() ;
   print($alu->add(9, 16) . "\n") ; # prints 25
   print($alu->subtract(9, 16) . "\n") ; # prints -7


You can also "study" existing classes like this:

   use Inline (
      Java => 'STUDY',
      STUDY => ['java.util.HashMap'],
   ) ;

   my $hm = new java::util::HashMap() ;
   $hm->put("key", "value") ;
   my $val = $hm->get("key") ;
   print($val . "\n") ; # prints value


Good luck,

Patrick
