This is a part of lecture presented by Ms.Rashmi Sharma Asst. professor of Biyani Girls College. This video is about Selection Sort. This algorithm sorts the data in ascending order. In Selection sort element at position 0 compared with all other element in the array. If the element found greater from other element then interchanged. The video is helpful for BCA, MCA, M.Sc. (IT) Students.

If you want to know error detection techniques then this video will solve your query.

This is a part of lecture presented by Ms.Rashmi Sharma Asst. Professor of Biyani Girls College. The video is about Stack Data Structure. Stack data structure is one of the most useful concepts in computer science. Stack is a data storage structure (Abstract data type). Unlike, arrays access of elements in a stack is restricted. It has two basic operations push and pop for insertion of an element and deletion of an element. The video is helpful for BCA, MCA, and M.Sc. (IT) Students.

Java is a difficult language but we make it easy to understand.

In Object Oriented programming the emphasis is on data rather than on procedure. Programs are divided into objects , Data is hidden and can’t be accessed by external design. The main concept are .
• Object:- Objects are identified by its unique name. An object represents a particular instance of a class. There can be more than one instance of a class.
• Class:- Class a blueprint for an object. This doesn’t actually define any data, but it does define what the class name means, that is, what an object of the class will consist of and what operations can be performed on such an object. No memory is allocated when a class is created.
• Data Encapsulation:- Data Encapsulation combines data and functions into a single unit called Class. Data Encapsulation enables the important concept of data hiding possible.
• Data Abstraction:- Data abstraction refers to, providing only essential information and hiding their background details .
• Inheritance:- Inheritance is the process of forming a new class from an existing class that is from the existing class called as base class, new class is formed called as derived class.
• Polymorphism:- The ability to use an operator or function in different ways in other words giving different meaning or functions to the operators or functions is called polymorphism.

In this Video, Karuna Yadav, Biyani Group of Colleges, explains about the shortest job first preemptive algorithm work. In this processes are scheduled according the arrival time.
