C++ vs Java vs Python

  • Difficulty Level : Easy
  • Last Updated : 03 Jan, 2020

These three programming languages are the most popular among the coders in terms of competitive coding and programming. C++ as of today in its efficiency, speed, and memory make it widely popular among coders. Java is platform-independent. It continues to add considerable value to the world of software development. Python requires less typing, provides new libraries, fast prototyping, and several other new features.
Let’s look at the comparison between these popular coding languages:

C++ Vs Java:

TOPICC++Java
Memory ManagementUse of pointers, structures, unionNo use of pointers. Supports references, thread and interfaces.
LibrariesComparatively available with low level functionalitiesWide range of classes for various high level services
Multiple InheritanceProvide both single and multiple inheritanceMultiple inheritance is partially done through interfaces
Operator OverloadingSupports operator overloadingIt doesn’t support this feature
Documentation commentC++ doesn’t support documentation comment.It supports documentation comment (/**.. */) for source code
Program HandlingFunctions and variables can reside outside classes.Functions and variables reside only in classes, packages are used.
PortabilityPlatform dependent, must be recompiled for different platformPlatform independent, byte code generated works on every OS.
Thread SupportNo built-in support for threads, depends on libraries.It has built-in thread support.

Python Vs Java:

Components can be developed in Java and combined to form applications in Python. Let’s see some of the differences in these two popular languages:

TOPICJavaPython
Compilation processJava is both compiled and interpreted language, which is first compiled and then interpreted into a byte code.Python is an interpreted programming language
Code LengthLonger lines of code as compared to python.3-5 times shorter than equivalent Java programs.
Syntax ComplexityDefine particular block by curly braces, end statements by ;No need of semi colons and curly braces, uses indentation
Ease of typingStrongly typed, need to define the exact datatype of variablesDynamic, no need to define the exact datatype of variables.
Speed of executionJava is much faster than python in terms of speed.Expected to run slower than Java programs
Multiple InheritanceMultiple inheritance is partially done through interfacesProvide both single and multiple inheritance

You can choose any language you want i.e. the one you are comfortable to work with. Technically it depends upon the job you want to accomplish. These 3 languages form the set of most popular languages among the college graduates’ coders and developers. I would suggest you stick with one language and achieve perfection in that. These languages may help you to achieve the level of coding you want to reach. I hope one day a coder reading this article may get inspired to develop a language similar to these and make a breakthrough for coders all around the world.
