Session simply means a particular interval of time. Session Tracking is a way to maintain state (data) of an user. It is also known as session management in servlet.

HTTP is stateless that means each request is considered as the new request. It is shown in the figure given below:
There are four techniques used in Session tracking:
- Cookies

	LinkedList vs ArrayList in Java
	Difference between LinkedList and ArrayList in JavaAll the differences between LinkedList and ArrayList has there root on difference between Array and LinkedList data-structure. If you are familiar with Array and LinkedList data structure you will most likely derive following differences between them:

	1) Since Array is an index based data-structure searching or getting element from Array with index is pretty fast. Array provides O(1) performance for get(index) method but remove is costly in ArrayList as you need to rearrange all elements. On the Other hand LinkedList doesn't provide Random or index based access and you need to iterate over linked list to retrieve any element which is of order O(n).
	2) Insertions are easy and fast in LinkedList as compared to ArrayList because there is no risk of resizing array
	and copying content to new array if array gets full which makes adding into ArrayList of O(n) in worst case, while adding is O(1) operation in LinkedList in Java. Array

	1)To Use Replace

	select replace(coName,'Char to Repalce','Char to Replace with')

	2)Relace the leading zeros of text
	SELECT REPLACE(LTRIM(REPLACE('094434580980','0',' ')),' ','0') FROM table1

	3)Replace Trailing zeros of the text
	SELECT REPLACE(RTRIM(REPLACE('094434580980','0',' ')),' ','0') FROM table1
