Creating a method to remove ArrayList elements from index x to index y

Question

As the title says, if I'm creating a method to remove a section of an ArrayList, how would I go about this.

If I have ArrayList<Character> se = {'a','b','c','d','e','f','g'} and want to return only "abg" I would call this method as such:

remove(2,5);

How could I create this method to remove not only the arg indexes but also everything in between?

Answer 1

list.subList(2, 6).clear()

does the job in one step.

Answer 2

Create a loop counting backward from 5 to 2 and remove the elements.

for(int i = 5; i >= 2; i--) ...
