Understanding Java and Its Features

a. What is Java?

Java is a high-level, object-oriented programming language designed to be portable and secure. It follows the “Write Once, Run Anywhere” (WORA) principle, meaning Java code can run on any platform with a Java Virtual Machine (JVM).

b. Key Features of Java

Platform Independence: Java programs can run on multiple operating systems without modification.

Object-Oriented: Encourages modular and reusable code.

Secure: Provides built-in security features like bytecode verification and exception handling.

Multithreading: Supports concurrent execution of multiple tasks.

Automatic Memory Management: Uses garbage collection to manage memory efficiently.
