Java is a popular programming language for developing mobile applications. The open-source community has contributed significantly to the growth and development of the Java ecosystem by creating various libraries, frameworks, and tools that make it easier to develop Java applications. Java is an open-source language, which means that its source code is available for free and can be modified by anyone. Java Standard Library is a set of reusable software components that help in writing efficient, portable, and reliable code. Java provides a vast collection of libraries, known as the Java Standard Library, which includes classes and interfaces for performing common programming tasks such as I/O operations, networking, and data manipulation. This means that Java code can be written once and run anywhere, making it an ideal language for developing cross-platform applications. Java code can be compiled on one platform and run on any other platform that has a Java Virtual Machine (JVM). One of the unique features of Java is its platform independence. Polymorphism: This is the mechanism of using a single method or object to represent different types of objects.Ībstraction: This is the mechanism of simplifying complex systems by breaking them down into smaller, more manageable pieces. Inheritance helps in reusing code and organizing classes in a hierarchy. Inheritance: This is the mechanism of creating a new class by inheriting the properties of an existing class. Java is an object-oriented language that supports the four pillars of object-oriented development:Įncapsulation: This is the mechanism of hiding the implementation details of an object and exposing only the necessary information to the outside world. In 1995, Sun Microsystems released Java to the public, and it quickly gained popularity due to its platform independence and ease of use. Java was developed as a language that could run on different platforms without the need for recompilation. It was initially called Oak, but later renamed Java. Java was developed by James Gosling and his team at Sun Microsystems in the early 1990s. Java is used for developing a variety of applications, including mobile apps, web applications, desktop applications, and games. Java is a case-sensitive, statically typed, compiled, general-purpose, and platform-independent language. It is an object-oriented language that supports various programming paradigms such as procedural, functional, and generic programming. Java is a programming language that was first introduced by Sun Microsystems in 1995.
