Java is a versatile, object-oriented programming language used for building a wide range of applications, from web to mobile and enterprise systems. Known for its “write once, run anywhere” capability, Java operates across platforms and devices. With robust libraries, frameworks, and a strong developer community, it enables scalable, secure, and efficient software solutions in diverse global industries.
