What is difference b/w Generic List and Arraylist, Generic List Vs HashTable, Generic List Vs No G..

Answer / debshankar bhattacharjee

Array List
1.Size/length of Array List can be increased or decreased
automatically.
2.Array list contains different types in the same array and
at the time of retrieving that value need to cast in
appropriate type.

Generic List:
Type of Generic list deceided at the time of compile and in
one generic list , we can include only any one type of
objects/value.
for example. if we write ,List<int> the this list can
contain only integer value.If we want to insert any string
then another list to be created.

Generic list is more efficient than arraylist

Answer / mani

Array list can increase and decrease size dynamically.You
donot use the REDIM keyword. You can access any item in
array using the INDEX value of the array position.

You can access array using INDEX value of array. but how
many times you know the real value of INDEX . Hashtable
provides way of accessing index using user identified key
value,thu removing the INDEX problem.
