what is Difference beetween Array and Hash Table.?
Answer Posted / pkl
An ArrayList behaves just like
an array, except that it will dynamically expand and
contract when you
add/remove elements to it. A HashTable is useful when you
want to
lookup objects indexed by a 'key' value. It also dynamically
expands and contracts but doesn't impose an order on the
elements like
an array does. Put a different way: you index elements in an
ArrayList with a numeric index, you index elements in a
HashTable with
a key. Such a key is often a string.
