Java, originally developed by Sun Microsystems and now maintained by Oracle Corporation, is a versatile and widely-used programming language known for its portability, performance, and security features. It follows the principle of “write once, run anywhere” (WORA), meaning Java applications can run on any device that supports Java without needing to be recompiled, thanks to its bytecode execution on the Java Virtual Machine (JVM).

Key features of Java include its strong object-oriented programming (OOP) principles, which encourage modular and reusable code through classes and objects. Java’s syntax is similar to C and C++, making it accessible for developers familiar with these languages while providing additional features such as automatic memory management through garbage collection.

Java is extensively used in a variety of applications, from web development (using frameworks like Spring and Hibernate) to mobile application development (using Android’s Java-based SDK). It also finds application in enterprise-level systems due to its scalability, reliability, and robustness. Java’s vast standard library provides APIs for networking, I/O operations, database connectivity (JDBC), and more, further enhancing its utility across different domains.
