a.remove(i)

is that what you are looking for?

Well what are you trying to get? Is it a specific Integer Object or a String? You can use the indexOf method to locate a specific word or number and then once you have gotten the index you can remove it.

code:

a.add ("the");
a.add ("here");
a.add ("ka");
a.add ("array");

a.remove (a.indexOf ("here"));


This removes the "here" object from your list. You should be using the java help for a simple question like this though...
