Check if player does not contain an item?

I have a quick question,

how would i check the players inventory to see if he does NOT contain a specific item/itemstack? Thanks!

 

Code:JAVA

 
PlayerInventory inventory = player.getInventory();
if(!inventory.contains(Material.SOME_ITEM) {
// He doesn't have SOME_ITEM
}
 

Or alternatively to the Material_SOME_ITEM you can use an ItemStack.

 

Really, a not check (!) is one of the most basic programming basics... Go learn more before you code.

 

What if I want to check if they have a specific amount of a given item?..

 

Code:java

if(inventory.contains(Material.[thematerial], [minimumamount]))
{
    // it contains at least [minimumamount] of [thematerial]
}
