What is Java

Introduction to Java

Java is a popular, high-level programming language first released by Sun Microsystems in 1995. It is an object-oriented language designed to have as few implementation dependencies as possible, making it platform-independent. Java is known for its portability, allowing developers to "write once, run anywhere" (WORA), which means Java code can run on all platforms that support Java without needing recompilation.

Key Features of Java

• Object-Oriented: Java uses objects for data manipulation, promoting flexibility and modular code.
• Platform-Independent: Java programs can run on any device that has the Java Virtual Machine (JVM).
• Robust: Java has strong memory management and exception-handling features.
• Secure: Java offers extensive security features to develop virus-free and tamper-free systems.
• Multithreaded: Java supports multithreaded programming, allowing multiple tasks to run simultaneously.

Where Java is Used

Java is used in a wide range of applications, including web development, mobile apps (especially Android), enterprise software, server-side applications, and large-scale systems like cloud services.

Benefits of Java

Java's main benefits include its simplicity, object-oriented approach, platform independence, security, and versatility in handling a variety of tasks. It is widely used in both academic and industry settings for these reasons.
