Solved Renaming Items

How do I rename items through code?
Because I have Items creating through and ItemStack its called goldhoe however I can not add someting like goldhoe.setName("Poop");
Eclipse will not recongnize setName is this the wrong code help me rename items!

 

Code:

ItemStack itemstack = new ItemStack(Material.DIAMOND, 1);
ItemMeta im = itemstack.getItemMeta();
im.setName("DIAMONDZZZZZZZZZZ");
itemstack.setItemMeta(im);

 

Sorry I got completely lost there do you have skype so you can help me out

 

Code:

//Here you create a new itemstack, you can also get a itemstack from an event/command etc
ItemStack itemstack = new ItemStack(Material.DIAMOND, 1);
 
//Here you get the ItemMeta for the item, ItemMeta is the lore, displayname etc
ItemMeta im = itemstack.getItemMeta();
 
//here we set the name for the item
im.setDisplayName("diamondzzzz");
 
//now we need to set the ItemMeta so the item gets the new name
itemstack.setItemMeta(im);
