Creating an instance of an object in Array List supplied by another ArrayList?

Newbie & Debugging Questions
#1 
     I have a class that I want to use JUST for the sole purpose of storing all of my different entities in the game. This way I can retrieve a certain entity randomly. In another class I also have an entity Array List that's for the actual game play. How would I be able to create a new instance of an entity from the first array list in the second Array List? I tried doing the same process as just about anything else but I started getting options like adding a static suppress warning and a bunch of other thingamajigs that I do not understand.

First:

public class EntityList {
	
	public static  ArrayList<Entity> entityList;
	
	public EntityList(){
		entityList = new ArrayList<Entity>();
		
		entityList.add(new Orc());
		
	}

}

2nd Class:

	switch(tileSetting){
			case "Friendly":
				break;
			case "Hostile":
                                WANT TO CREATE INSTANCE OF ENEMY HERE.
				break;
			}
