Java Programming Language

Java stands as one of the most widely embraced programming languages worldwide. It’s versatile and object-oriented, having made its debut in 1995. Java plays a central role in the functioning of countless applications and websites, operating across various devices, including data centers, laptops, gaming consoles, supercomputers, and even cell phones.

The concept behind Java is straightforward: “Write once, run anywhere.” This means that it’s not tied to any specific platform. Thanks to its nature as an interpreted language, it can be transformed to work on any type of computer. Being object-oriented, Java boasts some key attributes:

Inheritance: This allows objects within a certain class to inherit all the qualities of a parent object.

Polymorphism: Functions can multitask and serve multiple purposes, adding flexibility to coding.

Abstraction: Important features can be portrayed without getting bogged down in intricate details.

Encapsulation: Information and functions can be wrapped neatly into a single unit.

These combined elements make Java a powerhouse in the programming world, appealing to beginners and seasoned developers.

C++ Programming Language

C++ stands as a programming language shaped around the idea of objects. It came into existence in 1985 with the purpose of enhancing the C language by introducing the concept of classes. This language is the building block for creating various applications and websites. It truly shines when crafting applications on a lower level, handling native programming tasks, and creating immersive games.

The beauty of C++ is that it grants programmers more control over system resources and memory. Its code closely resembles the language that machines understand, granting a deep level of interaction. However, one thing to note is that C++ isn’t universally compatible with all platforms. Before it can be used, it must be transformed into a format that suits its intended platform.

But why is C++ so powerful? Well, its prowess is found in its versatility. It’s the driving force behind a plethora of everyday devices. Whether it’s the software running your computer, the engines powering your favorite video games, the browsers you use to surf the web, databases storing essential information, or even the algorithms behind Google’s search engine – C++ is the backbone.

Furthermore, C++ has found its way into a multitude of other areas:

Internet of Things (IoT) Devices: The technology powers smart devices and gadgets.

Machine Learning: The heart of the algorithms that enable computers to learn from data.

Virtual Reality (VR): The world-building blocks for immersive digital experiences.

Financial Technology: The foundation for secure and efficient financial software.

Medical Technology: Playing a role in medical equipment and software.

Telecommunications: Ensuring efficient communication across various devices.

Movie Production: Even the magic of cinema benefits from C++’s capabilities.

C++ is a coding marvel that transforms complex ideas into functional and tangible software, influencing countless aspects of our daily lives.

7.	Platform Dependency	Platform-independent, Java bytecode works on any operating system.	Platform dependent, should be compiled for different platforms.
8.	Portability	It can run on any OS hence it is portable.	C++ is platform-dependent. Hence it is not portable.
9.	Compilation	Java is both Compiled and Interpreted Language.	C++ is a Compiled Language.
10.	Memory Management	Memory Management is System Controlled.	Memory Management in C++ is Manual.
11.	Virtual Keyword	It doesn’t have a Virtual Keyword.	It has Virtual keywords.
12.	Multiple Inheritance	It supports only single inheritance. Multiple inheritances are achieved partially using interfaces.	It supports both single and multiple Inheritance.
13.	Overloading	It supports only method overloading and doesn’t allow operator overloading.	It supports both method and operator overloading.
14.	Pointers	It has limited support for pointers.	It strongly supports pointers.
15.	Libraries	It doesn’t support direct native library calls but only Java Native Interfaces.	It supports direct system library calls, making it suitable for system-level programming.
16.	Libraries	Libraries have a wide range of classes for various high-level services.	C++ libraries have comparatively low-level functionalities.
17.	Documentation Comment	It supports documentation comments (e.g., /*.. /) for source code.	It doesn’t support documentation comments for source code.
18.	Thread Support	Java provides built-in support for multithreading.	C++ doesn’t have built-in support for threads, and depends on third-party threading libraries.
19.	Type	Java is only an object-oriented programming language.	C++ is both a procedural and an object-oriented programming language.
20.	Input-Output mechanism	Java uses the (System class): System.in for input and System.out for output.	C++ uses cin for input and cout for an output operation.

22.	Structures and Unions	Java doesn’t support Structures and Unions.	C++ supports Structures and Unions.
23.	Parameter Passing	Java supports only the Pass by Value technique.	C++ supports both Pass by Value and pass by reference.
24.	Inheritance Tree	All classes in Java are subclasses of the Object class, hence Java only ever follows a single inheritance tree.	A fresh inheritance tree is always created in C++.
