What is Java?

Java is a popular programming language developed by Sun Microsystems, now owned by Oracle Corporation. It was released in 1995 and is designed to be platform-independent, meaning that programs written in Java can run on any device that has a Java Virtual Machine (JVM) installed.

Java is known for its simplicity, object-oriented structure, robustness, and security features. It is widely used in web development, mobile application development (Android apps are primarily built using Java), enterprise software development, and large-scale systems.

Some key features of Java include:

• Write once, run anywhere (WORA) - Java code can be written on one platform and run on any other platform with a JVM.
• Object-oriented - Java is based on the concept of objects, which encapsulate data and behavior.
• Memory management - Java automatically handles memory allocation and garbage collection.
• Security - Java provides a secure environment for executing code, with features like bytecode verification and a security manager.
• Rich standard library - Java comes with a large standard library that provides useful classes and methods for various tasks.

Overall, Java is a versatile and powerful programming language that continues to be widely used in various domains of software development.
