Virtual Inventory

Code:

    Inventory inventory;
    Player owner;
    String name;
   
    public VirtualInventory(Player p, String name) {
       
        this.inventory = Bukkit.createInventory(p, 27, name);
        this.owner = p;
        this.name = name;
       
    }
   
    public Inventory getInventory() {
       
        return this.inventory;
       
    }
   
    public Player getOwner() {
       
        return this.owner;
       
    }
   
    public String getName() {
       
        return this.name;
       
    }
   
    public VirtualInventory createInventory(Player p, String name) {
       
        VirtualInventory vi = new VirtualInventory(p, name);
       
        return vi;
       
    }
   
    HashMap<Player, VirtualInventory> inventories = new HashMap<Player, VirtualInventory>();
   
    public void saveInventory(Player p, VirtualInventory vi) {
       
        inventories.put(p, vi);
       
    }

This is my current code that I have in my VirtualInventory class, but I'm wondering how to check if a player already has a virtual inventory? How would I go about checking if the player is in the hashmap? (I don't have much experience with hashmaps).

 

@AppleMC
Use player#getInventory() to compare, perhaps?

 

Just check if the key is already in the map

Code:

Map<UUID, VirtualInventory> inventorys = new HashMap<>();

public boolean exist(UUID uuid) {
   return invetorys.containsKey(uuid);
}

//But if you are going to do something like this :

if(exist(uuid)) {
   VirtualInventory vi = inventorys.get(uuid); 

//You can just do this

VirtualIventory vi = iventorys.get(uuid);

if(vi != null) {

 

You can check if the hashmap contains the key using map.containsKey

 

Just a quick tip:
This will cause memory leaks, replace Player owner with String owner, to set it use p.getName(); and to get it use
Bukkit.getPlayerExact(owner);
