Item Id to Material?

SOLVED!

Material.getMaterial(id);

How would i take an item id (such as '56') to a MaterialData?
This is what i tried:

Code:

MaterialData itemId;
                    int itemIdRaw;
                    itemIdRaw = Integer.parseInt(args[0]);
                    itemId = setTypeId(itemIdRaw);

And the error i get from eclipse is "The method setTypeId(int) is undefined for the type HatMe", hatme is the name of my plugin.
Any ideas?
