How to filter inventory items that only contains a certein action?

[Psvxe]

I've tried a few things but none of them do exactly what I want it to do.

 

I don't want to write up all kind of food but instead I want to figure out what they use as food by checking their inventory. Now the problem is that they coud have different items beside food too in their inventory. 

This is why I came up with the idea to filter the items by the menu action they have. However, the API doesn't contain a method for that.

 

So now I'm working on my own method.

 

This is my concept idea;

 

1. Get all items in inventory and put them in a arrayList
2. Figure out if items in inventory has the action "Eat"
3. If not, remove from arrayList.

Now I'm just not sure how I'm going to create this.

 

Any help is welcome!

inventory.filter(new Filter<Item>() {
            public boolean match(Item item) {
                return item.hasAction("Eat");
            }
        });

Something like this?

List<Item> items = Arrays.asList(getInventory().getItems()).stream().filter(s -> s.hasAction("Eat")).collect(Collectors.toList());

        });

I'll try both of them. Looks promising. And way smoother than what I did.. haha Thanks!

An even nicer and actually readable solution would be (if you want to use java 8 with lambda expressions):

 

List<Item> food = inventory.filter( item -> item.hasAction("Eat") );

This is where i need to learn better methods all the ones above look better than what i would have done lel.

I would have gotten a all the items in inventory then for each item check if it has the action and if it does add it to a array list >.>

 

My way seems t0o much -  Im such a nub atm aha

The methods above only became accessible to us a couple of weeks ago so dw, yours was pretty much the way to go before that ;)

I'll get look up on lambda first.  Didn't had time to study that.

getInventory().filter(new ActionFliter<Item>(actions));

This will return a list of items with the action.

Actions I think is a varg aka array

getInventory().filter(new ActionFliter<Item>(actions));

This will return a list of items with the action.

You should probably move on and start using the Java filter :x
