what is Difference beetween Array and Hash Table.?..

Answer / 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.

Answer / salman mohammed

1.) arrays can be access from initial position. for example if we want to search 100th element then it will starts from 0 and then it will checks one by one and then it will reaches to 99. So here it is some what reliable but it tooks a lot of time for searching.

2.) Whereas in hash we are having key and value. Based on this we can easily identify the element which we need with in a short period of time than arrays.
So it is much reliable than arrays.

But both are important to us. Because both are having some good properties which helps us in our programming.
