Enterprise Applications such as banking applications.Desktop Applications such as acrobat reader, media player, antivirus, etc.There are many devices where Java is currently used. A detailed description of Hello Java example is available in next page.Īccording to Sun, 3 billion devices run Java. Let's have a quick look at Java programming example. Since Java has a runtime environment (JRE) and API, it is called a platform. Platform: Any hardware or software environment in which a program runs, is known as a platform. Since Oak was already a registered company, so James Gosling and his team changed the name from Oak to Java. James Gosling is known as the father of Java. Java was developed by Sun Microsystems (which is now the subsidiary of Oracle) in the year 1995. Java is a high level, robust, object-oriented and secure programming language. Java is a programming language and a platform. Java is an object-oriented, class-based, concurrent, secured and general-purpose computer-programming language. core Java programming tutorial is designed for students and working professionals. Only method signatures are written in the Interface. And all the methods are defined, independent of each other. Here we try to calculate the area of geometrical shapes, and for each shape, we have different methods. Java Interface Exampleįollowing is an ideal example of Interface in Java. With the syntax explained, let us now move ahead onto the next part, where we go through an example. So the Syntax of an Interface in Java is written as shown below. Now, let us check out how we can practically implement it-starting from its syntax to a real-time example. This way, all the methods, and classes are entirely independent and archives Loose Coupling. So, while using an interface, we define the method separately and the signature separately. The term Coupling describes the dependency of one class for the other. This type of ambiguity is known as the Diamond problem. Without Interface, the process of multiple inheritances is impossible as the conventional way of inheriting multiple parent classes results in profound ambiguity. Method Signatures make an Interface achieve complete Abstraction by hiding the method implementation from the user. An interface only stores the method signature and not the method definition. So we need an Interface in Java for the following reasons:Ībstraction is the critical concept of Object-Oriented programming techniques.
