1.Linear Data Structure:
						i. Static Data Structure: Array
									
						ii.Dynamic Data Structure: 
									 * Queue
									 * Linked List
									 * Stack

			2.Non-Linear Data Structure:
						     * Tree
						     * Graph

                  * embedded: portable, reuseable, reliable with embedded systems
                  * secure: compile code into a binary byte interpreted on JVM
                  * robust: utilizes strong memory management by bypassing security dilemmas
                  * architecture neutral: 4 bits of memory for both 32 & 64 bit architeure
                  * high performance: byte code is close to native code
                  * distributed: facilitates users to create distributed apps (RMI & EJB)
                  * multi-threaded: doesn't occupy memory for each thread, shares a common memory area
                  * dynamic: classes are loaded on demand also supports functions from native languages i.e. C, C++
