Arrays for lists.

I want to get the 2 parts in my list, if you don't get what I mean I have a players list that looks like this
Players:
Example : 50

The Example is the name and the 50 is the money, how would I get that second part? (The 50 part) And how would I separate the name from the int list.seperate?

TotallyNotWalshy You would need to use a HashMap. https://forums.bukkit.org/threads/help-with-hashmaps.95169/ this might help you

A HashMap is a list of values. Each value must have a key associated with it. You retrieve values from the list by giving a corresponding key. Keys and values can be any type (String, Integer, MyCustomClass etc).
Code:
 
        HashMap<String, Integer> map = new HashMap<String, Integer>();
        map.put("crow", 2); // Assigns a 2 to "crow" key
        map.put("apple", 6); // Assigns a 6 to "apple" key
       
        map.get("apple"); // Gets a value associated with "apple" key, which is 6
        map.get("tree"); // Gets a value associated with "tree" key, which is null, because you haven't assigned one
        map.get("crow"); // Gets a value associated with "crow" key, which is 2
     
Im guessing you need to so something like:
Code:
        HashMap<String, SomeClass> map = new HashMap<String, SomeClass>();
        map.put(player.getName(), something); // Assigns a "something" to a players name
 
        SomeClass something = map.get(player.getName()); // Retrieves that "something" assigned to a players name
You need to specify what you want to do if you want more details.

Aengo It's not working :/ Throws an NPE at this.
Code:java
.replace("{link}", links.get(player))

TotallyNotWalshy You need to check if the hashmap .containsKey(Player)
