Developed by James Gosling of Sun Microsystems in 1995, Java is one of the most widely used programming languages in the software industry. Without going any further, currently, it is estimated that there are about 10 million people who use Java to develop their applications, that about 3 billion mobile devices run Java and that its execution platform is installed on 1.1 billion computers . Don't you know what an interface is in Java ? Although this is one of the many options offered by this versatile programming language, mastering it is essential for those professionals who want to dedicate themselves to the software development sector or want to build their own applications under this platform . If this is your case and you want to know more about interfaces in Java, we will tell you all the details below. CTA Post What is a Java interface? Java is an object-oriented programming language that allows you to develop all types of applications, from websites or mobile applications to desktop software or video games. In this sense, and taking into account that it is an open source, cross-platform, powerful, fast and stable language, it is not surprising that it has become one of the standards of software development.
But what is a Java interface? It is one of the many elements that this language provides when writing code and developing applications. Specifically, it is a kind of template that allows you to pre-establish the content of one or more clPenderses. That is, it is a class that cannot be implemented by itself, but rather other clPenderses inherit and implement it. In this way, by using interfaces, it is possible to establish a set of rules that other clPenderses must strictly follow. What does an Europe Mobile Number List interface contain in Java? A Java interface contains a collection of abstract methods and constant properties that allow multiple inheritance to be activated , that is, different clPenderses starting from the same structure. The methods, which must always be public ( public ), are not implemented in the interface itself, but are only declared. However, the clPenderses that inherit the interface will be responsible for implementing it . In this sense, a Java interface has the following characteristics : It can contain method headers and public constants , never implementations.
The class cannot be instantiated, only implemented by a class . It cannot be extended . Interfaces can implement other interfaces . A class can implement multiple interfaces . You can declare static methods ( Static ) . On the other hand, it is necessary to explain the difference between a Java interface and an abstract class. While the first is completely declarative, the second can implement methods that will be inherited by other clPenderses. Additionally, abstract clPenderses can only be inherited once, while interfaces allow multiple inheritance. what-is-an-interface-in-java Advantages of an interface in Java As we have already mentioned, Java interfaces are a component that allows you to write code in a more flexible, reusable, reliable and secure way , key characteristics when we talk about high-quality software development . In this sense, what is a Java interface offers the following advantages: Order: declaring interfaces that will later be inherited by one or more clPenderses allows the code to be structured in an orderly manner. Simplify: declaring an object without specifying what it should do, that is, abstraction, allows us to simplify the design of an application. Flexibility : interfaces allow polymorphism, that is, similar objects can implement the same interface. This offers great flexibility.
