Help with static keyword

Hi, Im making a plugin that does a number of things, this part dealing with inventories.

This is my inventory class:

Code:java

public void onInventoryClick(InventoryClickEvent event) {
Player player = (Player) event.getWhoClicked();
Inventory inventory = event.getInventory();
 
if (inventory.getName().equals(myInventory.getName()))
{
if (event.getSlot() == 0) {
event.setCancelled(true);
player.closeInventory();
Join.Dynasty(player);
}
else if (event.getSlot() == 1) {
event.setCancelled(true);
player.closeInventory();
Join.Eldin(player);
}

and here is the Join class:

Code:java

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
 
public class Join {
 
    public String team;
 
    public void Dynasty(Player p){
        team = "d";
 
        if(p.getName().contains("[")&&p.getName().contains("]"))
            p.setDisplayName(p.getDisplayName().substring(p.getDisplayName().length()-10,p.getDisplayName().length()));
        else
            p.setDisplayName(p.getDisplayName() + ChatColor.DARK_PURPLE + " [" + ChatColor.GOLD + "DY" + ChatColor.DARK_PURPLE + "]");
        Bukkit.broadcastMessage(ChatColor.DARK_GRAY + p.getName() + ChatColor.RESET + " has joined Dynasty!!! (This is just a Alpha setting, more will follow in future updates)");
    }

Im getting an error in the inventory class at Join.*(player), it says that


Cannot make a static reference to the non-static method Dynasty(Player) from the type Join

I have no idea what this means, can you help me?

In your Join class just before the void put static

Code:java

public static void Dynasty(Player p){

 

Please, refrain from using static relentlessly without actually knowing the extends of what it does.

 

Please take a moment to think through what it means to use static. And learn OOP.

TL;DR to statics
