import org.bukkit.ChatColor;
import org.bukkit.GameMode;
import org.bukkit.Material;
import org.bukkit.block.Block;
import org.bukkit.entity.Entity;
import org.bukkit.entity.EntityType;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.BlockBreakEvent;
import org.bukkit.inventory.Inventory;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;

public class BreakBlock implements Listener {
    @EventHandler
    public void onPlayerBreakBlock(BlockBreakEvent event) {
        Block blockBroken = event.getBlock();
        Player player = event.getPlayer();
        Inventory inventory = event.getPlayer().getInventory();
        ItemStack itemStack = player.getItemInHand();


        if (blockBroken.getType() == Material.DIAMOND_ORE && player.getGameMode() == GameMode.SURVIVAL && player.getInventory().getItemInMainHand().getType() == Material.STONE_PICKAXE) {
            double d = Math.random() * 2;
            event.setCancelled(true);
            blockBroken.setType(Material.AIR);
            ItemStack diamonds = new ItemStack(Material.DIAMOND, (int) d);
            ItemMeta diamondsItemMeta = diamonds.getItemMeta();
            diamondsItemMeta.setDisplayName(ChatColor.DARK_GRAY + "Lucky Diamond");

            blockBroken.getWorld().dropItemNaturally(blockBroken.getLocation(), diamonds);

            blockBroken.getWorld().spawnEntity(blockBroken.getLocation(), EntityType.EXPERIENCE_ORB);
        }
    }
}

 

#spawnEntity returns the entity spawned. You can assign that to a variable and modify it.

Code:Java

ExperienceOrb orb = (ExperienceOrb) world.spawnEntity(location, EntityType.EXPERIENCE_ORB);
orb.setExperience(amountOfExperience);

#getItemMeta returns a copy of the ItemMeta, so you need to assign the modified instance to the item.

Code:Java

ItemMeta meta = item.getItemMeta();
meta.setDisplayName("Name");
item.setItemMeta(meta);
