The size() method of any collection returns an int, so I'd assume that the maximum number of elements that can go into a collection is Integer.MAX_VALUE. Of course, you may run into memory problems before you ever get that many items in a collection

The size method gives us the number of elements in the collection not the capacity.i want the maximum capacity whether it depends on the heap size or any limitation has been used please let me know

it gives the number of elements but think about it.... what if it exceeds the Integer.MAX_VALUE,would it compile to begin with. So logically max capacity will be Integer.MAX_VALUE as the size method can give the size till there only and compile successfully.

Work out what the maximum capacity of a linked list or a tree set would be for yourself.
