This course covers the concepts and implementations of Linear data structures such as Arrays, Stacks, Queues and Linked List. Relevant examples with pictorial representations are given for better understanding. The differences between static and dynamic data structures have been dealt with practical implementations. Applications of stack such as Infix to Postfix Conversion, Postfix Evaluation, Decimal to Binary Conversion and Palindrome checking have been elaborately discussed with suitable simple coding. Similarly, the applications of queue such as Stack implementation using Single queue and Double queues have been discussed in detail. Introduction to Liked List and its types such as Singly Linked List, Circularly Linked List, Doubly Linked List and Doubly Circular Linked List and its operations , Creation of node, Insertion of node at different positions of Linked List, Deletion of node from different positions, Traversal of Linked List have been explained with simple understandable code. This course also covers basics of object oriented programming such as writing functions, passing parameters to the functions and calling them. It also emphasizes on writing default constructor and parameterized constructors. This course includes almost 25 downloadable resource files, which includes concept wise java coding. The demo for each program have also been included in this course. All program files are made in txt format, so that the user can easily use it without any difficulty.
