If you are using a collection and not a list then consider making it an arraylist first before removing using indices. The Collection interface only defines remove(Object o) where you specify the actual object that you want to remove. To remove by specifying the index you can use ArrayList.

Ive made my list an ArrayList

coll=new ArrayList();
Then i did the above code.
Still i cannot remove the specified element

You need to store the data in a variable of type ArrayList

 ArrayList coll=new ArrayList();
