Java vs Python: The reality behind the usage and likeability of both!
If you're a developer or programmer, there must be at least one question that has been popping up in the back of your mind. If the questions seem like Java vs Python? or Java vs Python which is better? or Java vs JavaScript vs Python or Python vs Java which is easier? Java vs Python difference? Python vs Java performance? or Python vs Java future? Then you’re at the right place as we’re going to answer each of these questions for the budding developer like yourself!
Java
vs JavaScript vs Python
When it comes to Java vs JavaScript – Java is an OOP (Object Oriented
Programming Language) which was developed by Sun Microsystems which later was
acquired by Oracle. Programs or applications developed in Java will execute in
a JVM (Java virtual machine) by which we can run the same program on multiple
platforms and systems/devices etc. Whereas JavaScript is an object-oriented
scripting language that allows the creation of dynamic HTML pages with
interactive effects within a webpage. JavaScript was available in the browser
until Google chrome released its JavaScript engine as "node.js". Few
major differences between Java and JavaScript are:
OOPs – Java is an objected – oriented programming language that effectively uses objects to perform multiple actions based on relations between objects. JavaScript is an object-oriented language too which uses objects similar to Java.
Running Platform – Java applications and programs are run on JVM (Java Virtual Machine) which requires JRE and JRD to be installed on the said system whereas JavaScript can run on a web browser without any requirement of initial set up.
Java has a strongly typed language whereas JavaScript is a loosely typed language i.e. we need to declare variables using set objects before using them whereas in JavaScript we can flexibly use a variable.
Both Java and JavaScript languages are open source inherently as we can edit or modify the actual code and use it. Java achieves concurrency using a thread-based approach whereas JavaScript uses an event-based mechanism.
Java is a compiled and interpreted programming language and executed on JVM which requires JDK and JRE whereas JavaScript is interpreted which is executed on a browser and it is plain text.
Java has statically typed language whereas JavaScript is dynamically typed language as variables declared at compile time with the data type and JavaScript can accept different kinds of data types.
In Java, we have the support of constructor whereas in JavaScript constructor is a function and no rules for constructors in JavaScript like in Java.
Java is platform-independent with bytecode whereas JavaScript code is written is based on browser compatibility as some code might work on specific versions of browsers and doesn’t work on different versions of the same browser.
Java is a class-based programming language whereas JavaScript is prototype-based although it has object-oriented programming abilities.
Java has an implicit class scope whereas JavaScript has the implicit global scope.
Java has support for different numeric data types whereas JavaScript mostly deals with floating-point data types.
Java ends non-block statements with a semicolon whereas JavaScript uses semicolons at the end of certain lines.
JavaScript has support for closures where we can pass a function as an argument to another function whereas Java doesn’t have this support but can be achieved using an anonymous class.
Java has a switch structure that accepts only constants whereas JavaScript also has a switch structure that accepts any values.
Java has the support of annotations on classes whereas JavaScript has
decorators on the same declarations with different semantics.
Java has the support of Enum data type by which we can declare a set of constants whereas JavaScript doesn't have set constant declarations.
JavaScript vs Python
JavaScript can be used to run on the frontend whereas python is on server-side
programming or backend.
Python is strongly typed – no implicit conversion between types whereas
JavaScript is weakly typed.
Python has procedural programming whereas Java-Script does not have.
Python is a better-designed language that makes it easy to maintain whereas
JavaScript is poor.
Python is not good for mobile development whereas Java-Script is good.
Python is slow to run compared to JavaScript.
Python provides a huge standard library whereas JavaScript has a limited
standard library.
Python heavily relies on assignments with no difference between variables and
assignments whereas JavaScript doesn't relay.
Python has many libraries for scientific computing, data analytics, and machine
learning whereas JavaScript does not.
Python has support for many numeral data types like int, float, fixed-point decimal
whereas Java-Script mainly works on floating-point variables.
Python has an inbuilt REPL whereas JavaScript does not have.
JavaScript runs on both browser and server whereas python is mostly used for
server-side programming.
Python is easy to get started compared to JavaScript.
Python is easy to find new jobs compared to JavaScript this year.
Python object-based is nearly equal to JavaScript and Python supports a
programming style that uses simple functions and variables.
Java-Script has; a statement terminator whereas python has a newline.
Python vs Java performance?
When it comes to Java vs Python part, performance indeed is a yardstick to look
for. Java and Python are both some of the most robust popular and robust
programming languages. Java is nonetheless and faster and more efficient
because Python is a compiled language though as an interpreted language
whilePython has simpler, more concise syntax than Java then to it can perform
the same function as Java in fewer lines of code.
Speed and efficiency differences in
Java vs Python –
Python is an interpreted language that slows down Python programs during
runtime. To determine the variable type which occurs during runtime increases
the workload of the interpreter. Also, remembering the object type of objects
retrieved from container objects contributes to memory usage which further
slows programming in Python down.
Java programs are compiled directly. Java Virtual Machine (JVM) calls the
compiled code directly. Since the code is not interpreted, compiling does not
require processor time and memory usage. Theoretically, this can make a Java
program as fast as a native application.Java’s efficiency largely comes from
its Just-In-Time (JIT) compiler and support for concurrency. The JIT compiler
is a part of the Java Runtime Environment. It improves the performance of Java
programs by compiling bytecodes into native machine code "just
in time" to run.
Java
vs Python Fixing Bugs - In terms of Python, any or multiple bugs
introduced by the programmer will not be found until that line of code is
triggered or run. This can risk operational breakdowns and extend turnaround
time thus slowing down the program developed in Python. While Python leaves
objects vulnerable and open to mutation, in Java object mutations are
impossible. This leads to secure software development.
Conclusion
Java vs Python is the choice of the developer as to which one he or she would
use, but Python is mostly used by new developers as it is easy to understand
and develop. Thus, Java vs Python is also dependent on the developer’s acquired
knowledge and skills of either of the programming languages.
