helped gui refresh

Attempt to refresh the inventory created by the plug-in.
I'm trying to refresh every second.
Every second, I open the inventory using Repu, and I don't get any inventory, and I can't do anything because the server is closed and I can't do anything.

Code:

public void openShop(Player player, StockMData shop)
    {
        PDate = new Date();
        Gui gui = new Gui(this, shop);
        gui.setPlayer(player);
        if(getData().isTransaction()){
            while (true) {
                player.openInventory(gui.getInventory());
                if(player.getInventory() == null){
                    break;
                }
            }
        }
    }

 

Then, can I just put the method that opens the inventory in the ‘ run ’ function?

How do I end my inventory if it is not null?

 

@timtower
Using the timer to vary the price of the store.

 

Shouldn't you just update every click they do?
Instead of GUI use this: Inventory I = Bukkit. createInventory (null, (size), "title"); to open this inventory p.openInventory(I);

Code:

to update inventory
@EventHandler
public void onClick(InventoryClickEvent e) {

     
     Player p = (Player) e.getWhoClicked();

     if (p.getInventory().getTitle().equalsIgnoreCase("title of inventory") {
     p.updateInventory();
} 



     }
}
