Course description

Java is a high-level, object-oriented programming language designed with the principle of “write once, run anywhere” (WORA). This means that Java programs, once compiled, can be run on any system that has a JVM, regardless of the underlying hardware or operating system. Java’s syntax is similar to C and C++, but it incorporates several features that make it easier to use, such as automatic memory management (garbage collection) and a strong emphasis on object-oriented programming.

Key Features of Java

1. Object-Oriented Programming (OOP):

• Java is inherently object-oriented, which means that it organizes software design around data, or objects, rather than functions and logic. This approach allows for greater modularity and code reuse. Core concepts of OOP in Java include:

• Classes and Objects: A class is a blueprint for creating objects, and an object is an instance of a class.

• Inheritance: Mechanism where one class inherits the attributes and methods of another.

• Polymorphism: Ability to process objects differently based on their data type or class.

• Encapsulation: Restricting direct access to some of an object’s components and only exposing a controlled interface.

• Abstraction: Hiding complex implementation details and showing only the essential features of an object.

2. Platform Independence:

• Java’s platform independence is achieved through the use of the JVM. Java code is written and compiled into an intermediate form called bytecode. This bytecode can be executed on any machine that has a JVM, regardless of the underlying architecture.

3. Automatic Memory Management:

• Java handles memory management through an automatic process known as garbage collection. This feature helps in reducing memory leaks by automatically reclaiming memory used by objects that are no longer needed by the program.

4. Rich Standard Library:

• Java comes with a comprehensive standard library, known as the Java Standard API, which provides a wide range of tools for tasks such as data structures, networking, I/O operations, graphical user interface (GUI) development, and more.

5. Security:

• Java has built-in security features that protect against common vulnerabilities. It runs inside a secure environment called the sandbox, which restricts access to critical system resources. This is particularly important for Java applications running in a networked environment.

6. Multithreading:

• Java supports multithreading, allowing multiple threads (small units of a process) to run concurrently. This feature is essential for building applications that need to perform multiple tasks simultaneously, such as web servers and games.

7. Dynamic and Extensible:

• Java is designed to be dynamic and extensible. New classes can be created and loaded into the system as needed, and Java’s runtime environment can dynamically link libraries and classes.
