send List<String> to players

Hi,
I've got a list of Strings I wanna send the player.
It should be formatted like this:
--- Header ---
1. Message
2. Message
3. Message

I wanna array these messages after some numbers, can you tell me how to array it? (Got numbers which are greater than others)

But the main problem is I dont know how to send it to the player. My beginning of an tryal:

Code:java

 
            if(args.length > 0 && args[0].equalsIgnoreCase("list")) {
                List<String> bountys = bounty.getAllBountys();
                int size = bountys.size();
                player.sendMessage("--------> *** BOUNTYS *** <--------");
                player.sendMessage("More information: /bounty info <name>");
                while(size > 0) {
 
                }
            }
 

Thanks for your help.

player.sendMessage(bountys);
just a guess?
or a for loop of some sort to send them line by line

 

it would be:

Code:

for(int i=0;i<size;i++){
player.sendMessage((i+1)+". "+bountys.get(i))
}

 

Code:java

 
String[] stringArray = (String[])bountys.toArray();
player.sendMessage(stringArray);
 

Player has to sendMessage 's one takes a String for a parameter, the other takes a String[]

 

Or better, in my opinion:

Code:

int i = 0;
for(String message: bountys) {
++i;
player.sendMessage(i + ". " + message);
}

 

He needed the numbers.

I like doing it that way too, but he had allready set it up for the other way

 

Yeah i realized that after i posted it

 

I still love you

 

I did something similar before, but can to tell me how to sort numbers with the greatest on top?
Ive got a method getting all variables, but I've got one variable in it which is the "sorting"-variable.

 

You want the greatest number on top?

Code:java

for(int i=bountys.size(); i>=0;--i;){
player.sendMessage(i + ". " + bountys.get(i);
}

 

No its other wise, I know now how to send the messages but I got a bunch of numbers (can be 5 or 1000) and I want to sort them.

 

Where are the numbers.

 

These are the numbers:

Code:java

 
    @SuppressWarnings("null")
    public List<String> getAllBountys() {
        Player[] players = plugin.getServer().getOnlinePlayers();
        List<String> bountys = null;
        int i = 1;
        for(Player player : players) {
            if(existsBounty(player)) {
                String money = ""+getCustomConfig().getInt("bountys." + player.getName() + ".amount");
                String type = getCustomConfig().getString("bountys." + player.getName() + ".type");
                bountys.add(i + ": " + player.getName() + " | " + type + " | " + money);
                i++;
            }
        }
        return bountys;
    }
 

The number I wanna use is the amount (money as String)

 

remove your int i = 1 line and replace the inside of that if statement with this

Code:

int money = getCustonConfig...etc
int i = 1;
if(bountys.size()!=0){
  for(String s:bountys){
    if s.split("|")[2]<=money{
      bountys.add(player.getName()+ " | " + type + " | " + money,i)
      break;
    }
    i++
  }
}
else{bountys.add(player.getName() + " | " + type + " | " + money)
}

 

Will that sort the numbers by Size, with the biggest on top.

 

It wont "sort" any array, but it will ensure that your strings are sorted on the way in.

 

I dont wanna sort any arrays, I just wanna sort these entries in the List by Size.
SO what is this

bountys.add(player.getName()+ " | " + type + " | " + money,i)

so whats that money,i good for?

 

that satement adds the string player.getName()+ " | " + type + " | " + money
to the list bountys
at the index i
meaning that as it iterates down the list, its checking to see where money belongs, and then inserting it there

 

and how to read it out in the right direction then?

 

It is allready in order, this should read it out and add numbers
for(int i=0;i<bountys.size;i++){
player.sendMessage((i+1)+". "+bountys.get(i))
}

 

This don't works it's string and int, did you made a mistake or are changes needed?
And can you also explain me, what this split and stuff does?

 

String.split(String); creates an Array from the string, with the ParamString being the separator

an example:
String string = "Hello how are you?";
String[] split = string.split(" ");
its the equivalent of String[] split = {"Hello", "how", "are", "you?"};

 

lol it doesnt work because I forgot to put it in parenthesis. and i forgot to Integer.parseInt it. It should look like:
if (Integer.parseInt(s.split("|")[2])<=money)

Saber is correct, but this split in particular is meant to get the money value of the current string it is iterating over. Because the string is saved in the formatlayer.getName() + " | " + type + " | " + money
splitting it around "|" returns a list of [player.getName(),type,money]. Since the only one I am interested in is the value of money, that is the one I use. Now, I cant compare that string to a int unless I parse it first, which I forgot to do lol

 

Ok should work, do you know how to check if a number of an array exists? For example in a onCommand with args[1] how to check if that arg exists?

Another problem is that bountys is null when its default, but that throws an npe when it trys to check: if(bountys.size() != null)

 

to check if an arg exists simply use if (args.length >= whatever number arg you are trying to check).
Instead of initializing bountys as null, intialize it ias
List<String> bountys = new List<String>();

 

That dont works too it says: Can not instaniate the type List<String>

 

List<String> bountys = new ArrayList<String>();

ArrayList implements List

Also, you cant check if(bountys.size() != null){ because size() returns an integer, which can never be null, but it can return 0.

What I would do is have:

Code:java

int i = 0;
while(bountys.size()<= i){
player.sendMessage(bountys.get(i));
i = i+1;
}

That would go through all of the bountys and will stop when it gets above the size of the bountys.... When the command is run you can set i back to 0 so it runs properly.

You may need to see if bountys.isEmpty() to avoid possible errors.
