Help with random item giving

Hey guys! So I am making a new plugin for my server that does a dp for them where ever they are because Doing a drop party with 70 players and thousands of items lags my server
But the only thing I need is to give them random items, but I don't know how to do that could I have some help? This is what I have so far

Code:java

package me.josh.dp;
 
import java.util.ArrayList;
 
import org.bukkit.Bukkit;
import org.bukkit.Material;
import org.bukkit.OfflinePlayer;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.Listener;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin implements Listener{
 
    ArrayList<String> dp = new ArrayList<String>();
 
    public void onEnable() {
        System.out.print("DP Has been enabled!");
    }
 
    public void onDisable() {
        System.out.print("DP Has been disabled!");
    }
 
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
        if(cmd.getName().equalsIgnoreCase("DPOn")) {
            for(Player p : Bukkit.getOnlinePlayers()) {
                dp.add(p.getName());
            }
        }
        if(cmd.getName().equalsIgnoreCase("DPOff")) {
            for(Player p : Bukkit.getOnlinePlayers()) {
                for(OfflinePlayer po : Bukkit.getOfflinePlayers()) {
                    dp.remove(po.getName());
                    dp.remove(p.getName());
                }
            }
        }
        if(cmd.getName().equalsIgnoreCase("DP")) {
            Player p = (Player) sender;
            if(dp.contains(p.getName())) {
                sender.sendMessage("You have claimed your Drop party!");
                ItemStack test = new ItemStack(Material.DIAMOND_PICKAXE);
                p.getInventory().addItem(test);
            } else {
                sender.sendMessage("We are not having a dp at this time!");
            }
        }
        return false;
    }
 
}

To create a random you use:

Code:java

Random r = new Random();
int i = r.nextInt(Max Item code ID(I think 440 or something));
while(Material.getValue(i) == null){
    r = new Random();
    i = r.nextInt(Same max item code here);
}
player.getInventory().addItem(new ItemStack(Material.getValue(i));

Something along those lines, I wrote them by hand so I can't guaranty anything

 

@xXSniperzzXx_SD Sorry also I mean how do I make it give random things that I set? So let say

3 sets
First set: 1 diamondblock 1 pick
Second set: 2 diamondblock 3 pick
third set: 4 diamondblock 5 picks

How do I make it random on those?

So basically it is like this

I type /dpON
Players are then allowed to /dp and get the items
the items will be in like 5 sets

So they will either get 1,2,3,4,5 set

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Joshuak52 Just create a random int, then you can choose which set to give.

 

@xXSinperzzXx_SD but I want it to randomly give them that stuff so it randomly gives them 1,2,3,4 or 5

 

Then create a random between 1-5

I've already posted the code to create a random

 

@xXSniperzzXx_SD Is there any websites showing info on how to create ints?

 

Yeah, official javadoc:
http://docs.oracle.com/javase/7/docs/api/java/util/Random.html#nextInt(int)

 

Joshuak52
Just create one random integer (as shown above from se1by code),
Then create 5 if statements like;

Code:java

if(randomInt == 1){
//Your code
}else if(randomInt == 2){
//Your code.
}

And do that until you get to 5. This is pretty simple code, and if you don't know how to code java. You should learn Java before coding Bukkit API, it will be very helpful, just google TheNewBoston or something like that, and it should give you some tutorials

 

Ok I have created what I wanted but after I added the plugin I thought maybe I can have the 5th one with the best items, but I want this to be really hard to get like 1 out of 100 chance to get it. How can I do that?

 

You can use <, <=, > and >= instead of always using == for all the possibilities. So you can do like if the random int is between 1 and 5. (>=1 && <=5)

 

@MOMOTHEREAL but I need the 5th int really hard to get
