• Java VS Python
• 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 youre at the right
  place as were going to answer each of these
  questions for the budding developer like
  yourself!
• Java vs Python which is better? Java vs Python
  differences
• Java is a statically typed and compiled language,
  whereas Python is a dynamic, typed, an
  interpreted language. This single difference
  makes Java faster at runtime and easier to debug,
  but Python is easier to use or code and easier
  to read.
• Python has recently gained its popularity due to
  multiple reasons such as
• Due to it being communicable
• Easier to read
• Has vast libraries so easier for new programmers
  to grasp and ensures that they dont have to
  start from scratch
• Java is not only old but also is widely used so
  it also has a lot of libraries and a community
  for support.
• A deep look into Java vs Python not only tells us
  a lot about Java but also about Python and then
  goes on to tell us what both mean and when to use
  or not use both.
• Tableau Developer
• The difference between Java vs Python lies in the
  code that is

As per much research, Python is one of the top
ten fastest-growing languages and that Python
has been around longer than Java. Both Java and
Python are full of similarities as both of them
have strong cross-platform support and extensive
standard libraries, they both almost treat
everything as objects, and both languages
compile to bytecode, but Python is (usually)
compiled at runtime. They are both members of
the Algol family, although Python deviates
further from C/C than Java does. Node JS
Developer Java vs Python difference are as
follows
Parameters Python Java
Framework Python has lower lines of Frameworks as compared to Java and some popular ones are DJango and Flask. Java has a huge number of Frameworks and a few of them are Spring, Hibernate, etc.
Python has always been present in the agile space. Python has gained popularity for multiple reasons like the rise of the DevOps movement. Java enjoys more consistent refactoring support than Python because of its static type system which makes automated refactored more predictable and reliable, and on the other to the prevalence of IDEs in Java development.
Machine Learning Libraries Pytorch, Tensorflow, etc. MOA, Weka, Deeplearning4j, Mallet, etc.
Code Python has lesser and shorter lines of coding Java has long lines of coding
Syntax The syntax is similar to human language so it is easy to remember. The syntax is complicated as it shows an error if you miss semi-colon or curly braces.
Key Features Rapid deployment and dynamic typing as there is a lot lesser line of coding involved. Self memory management, Robust, Platform independence.
Speed and Databases Python is slower since it uses an interpreter and also determines the data type at run time. Pythons database access layers are a lot weaker than Javas Java is faster in speed as compared to Python. JDBC which is popularly known as Java Database Connectivity is most widely and popularly

• 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 doesnt 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 doesnt 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 a constant
  declaration.

• 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 has support for many numeral data types
  like, 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 while Python 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.
  Javas 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.

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 developers acquired
knowledge and skills of either of the
programming languages.
