Renaming Items

Hi,

Does anyone know how I can rename items so in-game they are renamed to what I want to name them as? Here's my list of what I want to name:

Sugar = Cocaine
Gunpowder = Heroine
Emerald = Crystalized Meth
Emerald Ore = Crystalized Meth Ore
Red & Brown Mushrooms = Shrooms
Cactus Dye = Marijuana
Cactus = Marijuana Plant
Seeds = Pills

Also, how can I rename certain items for certain ranks? For the cops I want

Stick = Searcher
Blaze Rod = Baton

If anyone has an idea, please comment, thanks

 

Using ItemMeta should work... Let me know if you need an example code.

 

Yeah can you give me an example? I tried that but I don't think it worked :/

 

If you wanted to rename something like Seeds to pills, first create an item stack that defines the material being renamed

Code:java

 
ItemStack pills = new ItemStack(Material.SEEDS);
 

Then, you want to get the item meta of that item stack

Code:java

 
ItemMeta pillsMeta = pills.getItemMeta();
 

Then, rename the item by setting display name.

Code:java

 
pillsMeta.setDisplayName("Pills");
 

 

And finish by setting that back to the item meta of the ItemStack:

Code:JAVA

 
pills.setItemMeta(pillsMeta);
 

 

Wait so it this all I put or do I have to put like a whole thing?

 

Everything IcPvp said and then what I said at the end

 

how do you do this please help me
