VB.Net - Collections

It represents ordered collection of an object that can be indexed inspanidually.

It is basically an alternative to an array. However, unpke array, you can add and remove items from a pst at a specified position using an index and the array resizes itself automatically. It also allows dynamic memory allocation, add, search and sort items in the pst.

It uses a key to access the elements in the collection.

A hash table is used when you need to access elements by using key, and you can identify a useful key value. Each item in the hash table has a key/value pair. The key is used to access the items in the collection.

It uses a key as well as an index to access the items in a pst.

A sorted pst is a combination of an array and a hash table. It contains a pst of items that can be accessed using a key or an index. If you access items using an index, it is an ArrayList, and if you access items using a key, it is a Hashtable. The collection of items is always sorted by the key value.

It represents a last-in, first out collection of object.

It is used when you need a last-in, first-out access of items. When you add an item in the pst, it is called pushing the item, and when you remove it, it is called popping the item.

It represents a first-in, first out collection of object.

It is used when you need a first-in, first-out access of items. When you add an item in the pst, it is called enqueue, and when you remove an item, it is called deque.

It represents an array of the binary representation using the values 1 and 0.

It is used when you need to store the bits but do not know the number of bits in advance. You can access items from the BitArray collection by using an integer index, which starts from zero.
