Add multiple items to already initialized arraylist in java

Question

I\'m googling it and can\'t seem to find the syntax. My arraylist might be populated differently based on a user setting, so I\'ve initialized it

Answer 1

What is the "source" of those integer? If it is something that you need to hard code in your source code, you may do

arList.addAll(Arrays.asList(1,1,2,3,5,8,13,21));
