ArrayList question. How to remove an Item

Question

I have an array collection that is going to contain a list of username.
I would like to fine one of the names and remove it from a list. How could I do this.
I am an Actionscript programmer so if I where to do this in AS I would do it like this.
for(var i:int=0; i<myarray.length; i++)
      if(myarray[i] == "matthew")
      myarray.remove(i);
}in Java I am not seeing a length property for the ArrayList

ArrayList al = new ArrayList();
al.add("aa");
al.add("ab");
al.add("ac");
al.add("ad");
for(int i=0; i<al.size(); i++){
if(al.get(i)=="ac"){
al.remove(i);
}here "ac" is removed from the arraylistAll I can do is shake my head and chuckle (and sigh).
Don't use == to compare Strings, and did you not read the rest of the thread that said it is not necessary to use the index? Not to mention, to either you or the OP, that 2 seconds of looking at the API docs would have let the both of you come to that same conclusion.
Also, if you do remove items in an ArrayList in this manner (for whatever reason) then loop through the ArrayList backwards, or you will skip an element every time you remove one.
Too little, too late, and so off target.
