Removing from an ArrayList

Edit on Github instead

To remove an item at a particular index in an arraylist, use the Object remove(int index) method.

Let's say we set up a list that will look like ["Hello", "Goodbye"]:

ArrayList<String> myList = new ArrayList<String>();

Now, let's remove the element at index 1:

myList.remove(1);       // Will return the String "Goodbye"

myList will be only ["Hello"].

If we wanted to save the String we removed, we could do that too:

String gone = myList.remove(1);         // Now, gone refers to "Goodbye"
