  • 15 Differences Between Java and Python

    1. Developer's View : 

    Python is better than java from developer’s perspective as it reduces lines of code to be written. Less code also reduces chances of making mistakes and can be maintained easily.Python is dynamically typed language and due to this reason programmers can be more productive.

    2. Complexity : 

    Python is much simpler and compact because like java we don't need to write a large amount of code.

    As the code is less it's very easy to maintain. But on the other hand it might become a little bit complicated to maintain a very large code in Python as it doesn't use braces.

    3. Platform Dependency :

    Platform independent means "Write Once Run Anywhere (WORA)".Java is platform independent as compiler creates Byte Code which is common for all platforms so it can run across any platform on the other hand Python is not.

    4. Execution speed :

    In terms of execution of a program Java is faster as compared to Python because the standard distributions (Java) include a JIT compiler that compiles bytecode to native code at runtime. This Just-In-Time (JIT) compilation is the reason for Java’s better performance. 

    5. Duck Typing :

    Java is statically typed language. Python is not dynamically typed language. In Python we never declare anything but this is not the case in java.

    For instance, consider we have two types Animal and Car that both have operation "run", however Car additionally supports "refuel". If this program just calls "run" on objects, it doesn't make a difference in the event that they are Animal or Car. This is called "duck typing" after the articulation "if it walks like a duck and quaks like a duck, it's a duck".

    There is no need to provide data types to variable in python but in java it is not the case, we need to explicitly provide data types while declaring variable.
    e.g 

    <p>&nbsp;//Java&nbsp;</p>
    <div>&nbsp;</div>
    <
    div>int a;&nbsp; &nbsp;//variable of integer type</div>
    <div>10;</div>
    <
    div>&nbsp;</div>
    <
    div>&nbsp;</div>
