PHP include on Java?

I'm trying to include fragments from other pages much like i'd do this on PHP:

Code:

---

// index.php?pid=1
$pid = $_GET['pid'];

switch($pid){
    case '1':
          include('register.php');
          break;
}

---

Now, i got on java as far as getting to the $pid var comparison, but i just can't seem to find a way to include the page dynamically:

Code:

---

                if (request.getParameter("pid") != null){
                    int id = Integer.parseInt(request.getParameter("pid"));
                    if( id == 1 ){
                      // INCLUDE FILE SYNTAX
                    }
                }

---

Anyway on doing this?

Thank in advance!

There is no analogue of PHP's include in Java. (There is a Java "include", but it does something different.)

What you will have to do is write the code within the if statement. Of course the code can call other code which resides in a different Java class (and hence a different file if you want to think of it that way). Something like:

Code:

---

if (request.getParameter("pid") != null){
    int id = Integer.parseInt(request.getParameter("pid"));
    if( id == 1 ){
      Registrar reg = new Registrar(id);
      reg.process();
    }
}

---

The code is rather whimsical, but I wanted to point out a couple of things. First the Registrar class is quite independent of the class where this code occurs and does not pick up any of its context as a result of being used. Anything it needs must be passed explicitly like id was. (Contrast this with PHP where the included code would inherit the variable scope.)

Secondly what is called are the methods of some class. With PHP you have a choice, but in Java all functionality is packaged within classes.

Only a saint could resist coding in language X with the idioms and patterns they are used to applying in language Y. But especially with respect to the patterns and overall construction of your program you would be well advised to learn Java by learning Java.

Hmmmmmm, so my question is: how do people reuse static pages like footer and menu while developing on Java? Can you only achieve this using frameworks?

Thanks for clarifying that btw, i had already tried those imports from Java but i couldn't get it to work...

Yes, a framework of some kind will be involved. JavaServerPages, part of JavaEE have an include tag that does what you would expect.
