Initializing ArrayList with some predefined values [duplicate]

Answer 1

I use a generic class that inherit from ArrayList and implement a constructor with a parameter with variable number or arguments :

public class MyArrayList extends ArrayList {
    public MyArrayList(T...items){
        for (T item : items) {
            this.add(item);
        }
    }
}

Example:

MyArrayListmyArrayList=new MyArrayList("s1","s2","s2");
