        Inner classes in Java are formed from nesting of one or more classes within another class. Like that of methods, variables of any class also have the possession of another class as its' component or member.

              Java Method Overloading

              If a class of a Java program has a plural number of methods, and all of them have the same name but different parameters (with a change in type or number of arguments), and programmers can use them to perform a similar form of functions, then it is known as method overloading.

                Java Constructor

                In this chapter, you will be dealing with constructors of Java, and learn about how they are used within a Java program and how they are useful Object Oriented Programming concept.

                        The concept of encapsulation is one of the four elementary concepts of Object Oriented Programming. Encapsulation can be defined as the procedure of casing up of codes and their associated data jointly into one single component, like a medicine capsule having different components packed as a single unit.

                          Java Inheritance

                          Inheritance is one of the major features of an object-oriented programming language. This is a special feature as it reduces programmers re-writing effort. In this tutorial, you will be learning about inheritance and its uses and types.

                            Java Interface

                            A large number of real-life applications need the concept of multiple inheritance. Java provides an alternative way of using multiple inheritance know as interfaces.


                              Multithreading in Java

                              Java provides built-in support for multithreaded programming. Multithreaded programming contains two or more parts that can run concurrently. Each piece of such a program is called a thread, and each thread defines a separate path of execution.
