Sorting Strings by Integers (Toplist)

Hey guys! I have a really big problem . I want to sort strings by integers. But I have really no plan how to do this. I have googled many threads. Found some functions like Comparator. But I don't know how to work with it with my script. I want to have a top 10 list in my plugin, where you can see the top levels of the players. Well, from highest level to the lowest. But I also want to get the int(player's level) from the config file.
Here my scripts:
How I save the levels to the config:

Code:

this.config.getAccountsConfig().options().header("Player accounts");
        this.config.getAccountsConfig().addDefault(player.getName() + ".Level", player.getLevel());
        this.config.getAccountsConfig().options().copyDefaults(true);
        this.config.saveAccountsConfig();

This just works fine.
And my toplist script:

Code:

else if(args[0].equalsIgnoreCase("top")) {
                        if(player.hasPermission("xpm.top")) {
                            Player[] users = this.getServer().getOnlinePlayers();
                           
                            player.sendMessage(ChatColor.DARK_GRAY + "---------- " + ChatColor.GOLD + "Xp Management" + ChatColor.DARK_GRAY + ": " + ChatColor.DARK_AQUA + "Top list " + ChatColor.DARK_GRAY + "----------");
                           
                            for(int n = 0; n < users.length; n++) {
                                int pos = n + 1;
                                                               
                                player.sendMessage(ChatColor.DARK_GRAY + "[" + ChatColor.GOLD + pdFile.getName() + ChatColor.DARK_GRAY + "] " + ChatColor.DARK_GREEN + pos + ". " + ChatColor.DARK_GRAY + users[n].getName() + ChatColor.GOLD + ": " + ChatColor.DARK_GREEN + "Level " + ChatColor.WHITE + users[n].getLevel());
                            }                           
                           
                            return true;
                        } else {
                            player.sendMessage(ChatColor.DARK_GRAY + "[" + ChatColor.GOLD + pdFile.getName() + ChatColor.DARK_GRAY + "] " + ChatColor.RED + "Error: You do not have permission to perform this command!");
                           
                            return true;
                        }
                    }

For now I have tested it with getOnlinePlayers(). This works fine, too, but not sorted from highest to lowest.
I would be so happy, if someone know how to create such sorting functions.
Thanks!

 

I also needed something like this in the past, this was my solutioon, mayby you can chance it to fit your own use it was part of an custom eggroulette plugin)

Code:java

 
Map<String, Integer> winners;
SortedSet<PlayerDataComparable> players = new TreeSet<PlayerDataComparable>();
		for (Map.Entry<String, Integer> i : winners.entrySet())
		{
			players.add(new PlayerDataComparable(i.getKey(), i.getValue()));
			// ...
		}
 
 
//print list:
		Iterator<PlayerDataComparable> i = players.iterator();
		int counter = 0;
		while (i.hasNext() && counter < ChatPaginator.CLOSED_CHAT_PAGE_HEIGHT)
		{
			PlayerDataComparable next = i.next();
			// broadcastMessage("Congrats " + next.getPlayer() + " for winning " + moneyFormat(next.getPrize()) + " at the place '" + name + "'");
			counter++;
		}

 

Ok. Will try my best. Thanks!
But what to write in the PlayerDataComparable class?

 

Nobody?

 

sorry, it was just late yesterday, I try to give you again the examply, whit al the things I used

Code:java

Map<String, Integer> winners;
SortedSet<PlayerDataComparable> players = new TreeSet<PlayerDataComparable>();
		for (Map.Entry<String, Integer> i : winners.entrySet())
		{
			players.add(new PlayerDataComparable(i.getKey(), i.getValue()));
			// ...
		}
 
 
//print list:
		Iterator<PlayerDataComparable> i = players.iterator();
		int counter = 0;
		while (i.hasNext() && counter < ChatPaginator.CLOSED_CHAT_PAGE_HEIGHT)
		{
			PlayerDataComparable next = i.next();
			// broadcastMessage("Congrats " + next.getPlayer() + " for winning " + moneyFormat(next.getPrize()) + " at the place '" + name + "'");
			counter++;
		}

Code:java

public final class PlayerDataComparable implements Comparable<PlayerDataComparable>, Cloneable, java.io.Serializable
{
	private static final long serialVersionUID = 123456L;
	private final String player;
	private final int prize;
 
	public PlayerDataComparable(String player, int prize)
	{
		this.player = player;
		this.prize = prize;
	}
 
	@Override
	public int compareTo(PlayerDataComparable o)
	{
		if (o.prize > this.prize)
		{
			return -1;
		}
		if (o.prize < this.prize)
		{
			return 1;
		}
		return String.CASE_INSENSITIVE_ORDER.compare(this.player, o.player);
	}
 
	@Override
	public boolean equals(Object obj)
	{
		if (obj == null)
		{
			return false;
		}
		if (getClass() != obj.getClass())
		{
			return false;
		}
		final PlayerDataComparable other = (PlayerDataComparable) obj;
		if ((this.player == null) ? (other.player != null) : !this.player.equals(other.player))
		{
			return false;
		}
		if (this.prize != other.prize)
		{
			return false;
		}
		return true;
	}
 
	@Override
	public int hashCode()
	{
		return this.player.hashCode() ^ this.prize;
	}
 
	@Override
	public String toString()
	{
		return "PlayerDataComparable{"
			+ "player=" + player
			+ ", prize=" + prize
			+ '}';
	}
 
	@Override
	public PlayerDataComparable clone() throws CloneNotSupportedException
	{
		return (PlayerDataComparable)super.clone();
	}
 
	public String getPlayer()
	{
		return player;
	}
 
	public int getPrize()
	{
		return prize;
	}
}

 

Got it working now on my own way
How? First I created a new class which implements a Comparable:

Code:

public class User implements Comparable<Object> {
    private String name = "";
    private int level = 0;
 
    public User(String name, int level) {
        this.name = name;
        this.level = level;
    }
   
    public String getName() {
        return name;
    }
   
    public int getLevel() {
        return level;       
    }
 
    @Override
    public int compareTo(Object s) {
        User p = (User) s;
        if(level < p.getLevel()) {
            return -1;
        } else if(level == p.getLevel()) {
            return 0;
        }
        return 1;
    }
   
    /*public static void main(String[] s) {
        User[] toSort = new User[5];
        toSort[0] = new User("A",34,1);
        toSort[1] = new User("B",5,2);
        toSort[2] = new User("C",67,3);
        toSort[3] = new User("D",1,4);
        toSort[4] = new User("F",10,5);
       
        System.out.println("Vor dem Sortieren");
        for (User p : toSort){
            System.out.println("Name: " + p.getName() + ", Punkte: " + p.getLevel());
        }
        Arrays.sort(toSort, Collections.reverseOrder());
       
        System.out.println("Nach dem Sortieren");
        for (User p : toSort){
            System.out.println("Name: " + p.getName() + ", Punkte: " + p.getLevel());
        }
    }*/
 
}

And here how I used it in the onCommand:

Code:

else if(args[0].equalsIgnoreCase("top")) {
                        if(player.hasPermission("xpm.top")) {
                            Player[] players = this.getServer().getOnlinePlayers();
                            User[] users = new User[players.length];
                           
                            player.sendMessage(ChatColor.GRAY + "---------- " + ChatColor.GOLD + "Xp Management" + ChatColor.GRAY + ": " + ChatColor.DARK_AQUA + "Top list " + ChatColor.GRAY + "----------");
                           
                            for(int i = 0; i < players.length; i++) {                               
                                users[i] = new User(players[i].getName(),players[i].getLevel());
                            }
                            Arrays.sort(users, Collections.reverseOrder());
                            for(User u : users) {
                                int pos = this.position;
                               
                                player.sendMessage(ChatColor.GRAY + "[" + ChatColor.GOLD + pdFile.getName() + ChatColor.GRAY + "] " + ChatColor.DARK_GREEN + pos + ". " + ChatColor.GRAY + u.getName() + ChatColor.GOLD + ": " + ChatColor.DARK_GREEN + "Level " + ChatColor.WHITE + u.getLevel());
                               
                                this.position = pos + 1;
                            }
                            this.position = 1;
                           
                            return true;
                        } else {
                            player.sendMessage(ChatColor.GRAY + "[" + ChatColor.GOLD + pdFile.getName() + ChatColor.GRAY + "] " + ChatColor.RED + "Error: You do not have permission to perform this command!");
                           
                            return true;
                        }
                    }

Also created a "private int position = 1;" to set the position in the top list.
But thanks for your help ferrybig
