Here we will see some basic differences between C++, Java and the Python. At first we will see the C++ and Java differences, then the Java and Python differences.
|Memory Management||It uses pointers, structures, unions and references||It does not support pointers. It supports references. It also supports Threads, interfaces|
|Libraries||Low level functional libraries||Wide range of library, with various functionalities|
|Multiple Inheritance||Supports multiple inheritance using normal classes||Supports multiple inheritance with only interfaces (pure abstract classes)|
|Operating Overloading||Operator overloading is supported||Does not support operator overloading|
|Program Handling||Functions and variables can reside outside of the classes||Functions, variables can only be there inside classes or packages|
|Portability||Code is dependent on platform. It needs recompile||Platform independent. compiled version can run any platform which has the JVM installed|
|Thread Support||No built-in threads||Built-in threads are present|
Now let us see the differences between Java and Python.
|Compilation process||Code is compiled using compilers||Code is interpreted using Python interpreter|
|Code Length||Higher number of code lines as compared to Python||Less number of code lines as compared to Java|
|Syntax||Each block will be separated using braces, and each line will be terminated using semicolon||Each block is separated using indentation. The line ending does not need semicolon|
|Ease of typing||This is strongly typed. Each variable needs datatypes that are defined earlier||Dynamic in nature. We do not need to specify the datatypes.|
|Speed of execution||Java is faster than python||Python is slower than Java|
|Multiple inheritance||Supports multiple inheritance with only interfaces (pure abstract classes)||Supports multiple inheritance|
