Remove contiguous duplicate elements from an array list in Java (with panache)

So there lives an array list:

  ArrayList<Character> charOutput = new ArrayList<Character>();

He eats chars, so he ends up like this:

  [0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, *, *, *, *, *, *, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4]

But this is quite grotesque in our particular applicaiton. we want to trim him down, such that, finally, he looks like this:

 [0,1,*,3,4]

So, how to do that?
