Java-1

Introduction
Java is one of the world's most popular and widely used programming languages. It was developed by Sun Microsystems in 1995 and is now maintained by Oracle. Java is known for its simplicity, security, platform independence, and object-oriented programming features.

One of Java's biggest advantages is its "Write Once, Run Anywhere" (WORA) capability. This means that a Java program can run on any device that has a Java Virtual Machine (JVM) installed, regardless of the operating system.

Java is widely used for developing:

Desktop applications
Web applications
Mobile applications (Android)
Enterprise software
Cloud-based applications
Games and embedded systems
