Solved Fireworks Error Code!

So My Fire Works have been going off 100% when the player mines. I want it to Just Go off when The Player Breaks the Blocks Having a 2% chance. The Chance for the message is %2. But the fireworks is 100% Going off. How do i make it go off when the 2% chance is hit?

Code:

package me.DeadlyDeath001.test;

import java.util.Random;

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.World;
import org.bukkit.block.Block;

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.ItemStack;
import org.bukkit.inventory.meta.FireworkMeta;
import org.bukkit.plugin.java.JavaPlugin;
@SuppressWarnings("unused")
public class BlockDrop extends JavaPlugin implements Listener {
    @Override
    public void onDisable() {
            System.out.println(getName()+" Is now disable!");
    }

    @Override
    public void onEnable() {
            System.out.println(getName()+" Is now enable!");
            getServer().getPluginManager().registerEvents(this, this);
            getConfig().options().copyDefaults(true);
            saveConfig();
    }
  
    @EventHandler
    public void onBlockBreak(BlockBreakEvent event) {
        Block block = event.getBlock();
        Player player = event.getPlayer();
        World world = block.getWorld();
        Random rand = new Random();
        int number = rand.nextInt(100);
        {
        if (block.getType() == Material.STONE) {
            if(number <= getConfig().getInt("StonePercentage"))
            player.sendMessage(getConfig().getString("StoneMessage"));
            Bukkit.dispatchCommand(Bukkit.getServer().getConsoleSender(), "eco give" + player.getPlayer() + "200");
            launchFirework(player.getPlayer(), 69/*random number I thought of first*/);
        }
        }
    }

    private void launchFirework(Player player, int i) {
        Firework fw = (Firework) player.getWorld().spawn(player.getEyeLocation(), Firework.class);
        FireworkMeta meta = fw.getFireworkMeta();
        //use meta to customize the firework or add parameters to the method
        fw.setVelocity(player.getLocation().getDirection().multiply(1));
        //speed is how fast the firework flies
    }
   
      
    }

 

@DeadlyDeath001

What is the error? Maybe its because you dos not add effects to the fireworks?

 

Error: The fireworks is suppose to go off with the 2% Lucky Break But Instead the Fireworks goes off 100% and the message 2%

 

@DeadlyDeath001 You have no "{" after the if which checks the number. That means just the next line will be affected by the if. Do sth like this:

Code:

if (block.getType() == Material.STONE) {
  if(number <= getConfig().getInt("StonePercentage")) {
    player.sendMessage(getConfig().getString("StoneMessage"));
    Bukkit.dispatchCommand(Bukkit.getServer().getConsoleSender(),"eco give"+player.getPlayer() +"200");
    launchFirework(player.getPlayer(), 69/*random number I thought of first*/);
  }
}
