Java Tutorial

Java is an object-oriented(OO) programming language,an application consists of a series of objects that ask services from each other. Each object is an instance of a class that contains a blueprint description of all the object’s characteristics. Contrary to procedural java programming, an object bundles both its data(which determines its state) and its procedures(which determines its behavior) in a coherent way. An example of this could be a student object having data elements such as ID, name, date of birth, email address, and so on, and procedures such as register for course, is passed, and so on. A key difference between OO and procedural programming is that OO uses local data stored in objects, whereas procedural programming uses global shared data that the various procedures can access directly. This has substantial implications from a maintenance viewpoint. Imagine that you want to change a particular data element. In procedural programming is that OO uses local data that the various procedures can access directly. This has substantial implications from a maintenance viewpoint.
