Fundamentals Basics for Java

Before going to the topic we must know  Introduction about Java:                         Java  is one of the most popular programming languages used to create Web applications and platforms. It was designed for flexibility, allowing developers to write code that would run on any machine, regardless of architecture or platform.                         According to Java more than 1 billion computers and 3 billion mobile phones worldwide run Java. Let us see what is the  Uses in Java:                          Java is used to build applications and platforms for a number of devices, including computers, laptops, gaming consoles, Blu-ray players, car navigation systems, medical monitoring devices, parking meters, lottery terminals, and smartphones.                        It is also a key language for networking, particularly for data centers that store and transfer Web-based data. Why Java is more popular  in Modern World????                      We all know so

                   JAVA PROGRAMMING FOR BEGINNERS Introduction to Java                                            Java is defined by a specification and consists of a programming language, a compiler, core libraries and a runtime (Java virtual machine) The Java runtime allows software developers to write program code in other languages than the Java programming language which still runs on the Java virtual machine. The  Java platform  is usually associated with the  Java virtual machine and the  Java core libraries .   Properties of Java ·         Platform independent ·         Object-orientated programming language ·         Strongly-typed programming language ·         Interpreted and compiled language ·         Automatic memory management Java virtual machine         The Java virtual machine (JVM) is a software implementation of a computer that executes programs like a real machine.                    

              JAVA PROGRAMMING FOR                                            BEGINNERS Basic concept oops                    ObjectOriented Programming is a programming concept that works on the principle that objects are the most important part of your program. It allows users create the objects that they want and then create methods to handle those objects.  Class          The class is a group of similar entities. It is only an logical component and not the physical entity.  Example -Mercedes, BMW, Toyota   Object                                 An Object contains both the data and the function, which operates on the data. Example - chair, bike, marker, pen, table, car, etc. Inheritance         It’s creating a parent-child relationship between two classes. It offers robust and natural mechanism for organizing and structure of any software.  Polymorphism             Polymorphism refers to the ability of a variable, object or function to take on mul
