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.
| Topic | C++ | Java |
|---|---|---|
| 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.
| Topic | Java | 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 |
