Testing if player has an item

i want to test if a player has a specific item, and how many of that item, so that if they have over 4 sticks, it will give them 2 logs, and it will take the 4 sticks, but if they have more than 4, those will stay

 

Code:

if(Arrays.asList(p.getInventory().getContents()).contains(item)){
  // do some stuff if they got the items required
}

 

Yeah i've found that, but how do i test to see if they have a specific amount of that item

Look into ItemStack to check if a specific stack of items is greater than 4 etc

Code:

if(Arrays.asList(p.getInventory().getContents()).contains(item)){
  Material targetMat = Material.STICK; // or whatever you are trying to count the amount of
  int amount = 0;
  for(ItemStack is: p.getInventory().getContents()){
    if(is.getType().equals(targetMat)) amount+=is.getAmount();
  }
 
// amount is how much of the item there is TOTAL (all stacks combined)
// .getAmount() would only return the amount in one stack
}
