Introduction to Java
What is Java?
Java is a high-level, object-oriented programming language widely used for its portability, security, and platform independence. Designed to "write once, run anywhere," Java programs can run on any device with a Java Virtual Machine (JVM), making it popular for applications spanning from web servers to mobile devices.
History and Evolution of Java
Java was developed by Sun Microsystems, with James Gosling as the lead designer, and released in 1995. Initially created as an interactive television platform language, Java quickly evolved into a mainstream programming language for web applications with the rise of the internet. Over the years, Java has continued to evolve through regular updates, with notable changes in memory management and security features that keep it competitive for modern development.
Key Features of Java
Java’s popularity stems from its portability and extensive libraries. The JVM provides an environment where Java code can be compiled once and executed anywhere, while the language’s robust libraries simplify development. Additionally, Java’s emphasis on security makes it suitable for networked applications.
