Help with getWorld()

Code:

            List worlds = server.getWorlds();
            for(int i = 1;  i < worlds.size(); i++){
            String world = worlds.get(i).toString();
            String wn = server.getWorld(world).getName();
            String we = server.getWorld(world).getEnvironment().name();
//Do stuffs with strings wn & we
} 

So, This code is **** up worldwarp 2.0.
Gives me NullPointerException at the line String wn = server.... (4:th line)
Anyone see's whats wrong? I can't and eclipse gives me no errors. builds without warnings

 

String world = worlds.get(i).toString();
You get the world as an World-object and then convert it to String. First of all, this and the following line is not necessary, because server.getWorlds() already gives you World-objects.

BTW, you should add a generic to the List-declaration at the first line
List<World> worlds = server.getWorlds();

world.get(i) already returns your World and you can call stuff like getName() and getEnvironment().

Umm, I explained kinda messy, but I hope I helped

 

This might help:

PHP:

// get list of worlds
final List<World> worlds = server.getWorlds();

// go through the complete list of worlds, one at a time and *do stuff*
final Iterator<World> iter = worlds.iterator();
while(iter.hasNext()) {
    // get next world
    final World world = iter.next();

    // get world name
    final String wn = world.getName();

    // get world environment
    final Environment we = world.getEnvironment();

    // Do stuffs with wn & we
}// end while 

Remark: I hate the post add/edit functionality of this forum. Click somewhere else in the browser window and everything is gone. What happened to plain old <textarea> without all the fancy crap?

 

You can still click the "More Options..."-button to have it displayed in its own window. And the textarea mode for plain text can be reached with the -symbol (top right corner of the editor).


@Raz
I just noticed you started your loop with int i = 1 in the OP. Why not 0?

 

Ahh, thanks a lot, Bone008, you just made my life a lot easier. I had to type my previous post three times which got me a little p-o'd.

 

Thanks to booth of you Works great now.
I See my errors clearly right now. I Guess coding to 03:00 in the morning isn't to recommend, atleast not without coffe

 

Coding till 6am is even better.
