Difference Between C++ vs Java vs Python
Categories: Java 8(JDK1.8)
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:
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
