Solved ArrayLists from multiple classes. [UNSOLVED]

Sorry I have been posted a lot of threads lately but I have come across a lot of problems. This is one of them... I have created an arraylist in a class and want to use it in other classes. I have looked up and found many people having the same problem, however they have solved theirs. I am struggling big time! This is my code so far...
Thanks in advance

P.S I will learn from my mistakes

CODE:

ArrayList:

Code:java

ArrayList<Player> parkour2 = new ArrayList<Player>();

Other Class:

Code:java

public static Parkour parkour;
 
public LeaveGame(Parkour instance) {
parkour = instance;
}

Usage:

Code:java

parkour.parkour2.add(p);

 

Assume Class one's name is ClassOne and ClassTwo's name is Class two.

ClassOne:

Code:java

public static ArrayList<String> list = new ArrayList<String>();
 

ClassTwo:

Code:java

ArrayList<String> list = ClassOne.list;

I'm surprised that you couldn't find the answer to this though. I had the same problem a while ago and found it within 10 minutes

 

Ironraptor3 Why use static? It kinda ruins the object oriented design.

 

Rocoty meh. OH and don't save players to lists. I didn't see that at first

 

• 
  
  public static ArrayList<String> list = new ArrayList<String>();
  
  
  
  

Then to get it in another class:

private [pluginname] plugin;

public [classname] ([pluginname] plugin) {

this.plugin = plugin;
}

to get the arraylist:

this.[your main class] .list
