Question

Java, Python, and C++ are three of the most useful programming languages to learn. Compare the functionalities of all three programming languages. Why would you choose one language over another? Provide code examples demonstrating their usefulness in a real-world scenario.

Answer 1

Ans: -

Java, Python and C++ are the most commonly used languages in industries now a days. Each programming language has their own methods and syntax to write a code. Each language has different features and limitations. But all the three languages are useful to build the different applications and softwares in their own coding techniques and functionalities.

Here are the comparison of different functionalities and features of all three languages: -

Java: - Java programming language is very advance programming language which is used for developing high level applications and software. The syntax of java programming language is related to the C++ language. So, after learning C++ it becomes easy to learn java programming language.

The concept of object is also included in java which makes java an object-oriented language. It involves Polymorphism i.e. operator overloading and overriding, inheritance, Classes, encapsulation and abstraction which makes the Java language more secure and advance.

Java language can easily run on different platforms that’s why it is platform independent.

Java programming language is more secure as it has its own run time environment and it also do not have concept of pointers.

The memory management system is very powerful in Java as it has its own environment structure. It incudes error handling.

C++: - C++ language is very simple and easy to learn. The syntax is easy understandable which makes C++ programming language easy to learn.

Unlike Java Language, C++ is not platform independent language it requires the change in code while executing at different platforms. C++ language takes the help of operating system for its Run time environment.

C++ also includes polymorphism, inheritance, Classes and encapsulation etc. C++ programming language has fast execution and compilation mechanism which makes it more useful. It is also an object-oriented language.

C++ provides structures and pointers. Pointers are useful to deal with memory management.

The concept of recursion is present in C++ which provides the function reusability.

C++ has rich library and functions.

Python: - Python programming language is the most easy and simple language in all of the three. Its syntax is very simple and easy to understand.

The most advanced feature and functionality of Python programming language is that this programming language is used in machine learning and Artificial intelligence.

Automation also uses python language to perform different automated tasks.

The other programming languages like Java, C++ and C etc. can be easily integrated with the Python language which makes the python language easy to integrate.

Python programming language can also be used to design the interactive User Interface and applications.

It has rich library and different functions which makes it more powerful language.

All three languages have their own features and functionalities. Different language has its own strengths and limitations.

Python programming language is used in machine learning and automation.

Java programming language is used to develop high level applications and web services.

C++ language is used to design games and operating system etc.

So, we can use different languages according to our requirements to develop different types of applications and softwares.
