Java vs Python – Top 9 important Comparisons You Must Learn

Differences Between Java vs Python

A programming language is a language that describes a set of rules that can be used to give various types of output. Python, Java, C, C++, Fortran, Perl all are high-level languages. Java is high level, an object-oriented programming language developed by Sun Microsystem in 1995. Java runs on many platforms like Windows, Mac OS, Linux. The latest release of Java is Java SE 8. Java works on the principle of write once run anywhere. Java is object-oriented, platform independent, simple, secure, Robust, interpreted, multithread, high performance and dynamic. Python is an object-oriented, high-level and all in one programming language. It was developed by Guido Van Rossum during 1985- 1990. Python is highly readable and easily understandable. python uses simple English keywords very often whereas other languages use punctuation. Python is easy to learn, easy to read, interactive mode, portable, extendable, databases, scalable.

Key Differences Between Java vs Python

Below are the most important Differences Between Java vs Python

• Java language is more about syntax, if one can forget to add curly braces or semicolon in the end then this will show error as your output. But there is nothing like that with python there is no need of semicolon and curly braces in the end but python follows indentation process so that it will make your code readable.
• Java programming is statically typed means that one has to explicitly mention the data type of variable if datatype (int, float, double, character) does not mention then the error will occur in program. Python is dynamically typed means one has directly assigned a value to a variable at the runtime it will assume data type.
• Java codes are more complex than python codes. If one can write a hello world program in both then you can observe the complexity of the code, 4 lines of code in Java and same hello world program in python will be of 1-line code.
• If someone works on a project which requires a fast speed then java is the best choice because python is an interpreter and it will assume data type of a variable at runtime due to which it becomes slower than java.
• Java has JDBC (Java DataBase Connectivity) which is widely used connectivity with different databases like SQL, SQOOP etc. and JDBC is very popular also but Python’s database access layers are weaker than Java’s JDBC. This is why it rarely used in enterprises.
• Java enjoys more undeviating refactoring support than python thanks to its static type system and universality of IDE’s in development. Python has always had an existence in the talent space and has the popularity for many reasons including Data Science and DevOps movement.
• Java architecture: -JVM (Java Virtual Machine) is an engine that gives runtime environment to operate the Java Code. It turns Java bytecode into machines language. JVM is a chunk of JRE (Java Run Environment).

• Python Interpreter translates your source code into machine-independent bytecode (. pyc).
• Stores .pyc file __PyCache__ folder.
• When you run the same program (Without changes) then it will use this bytecode without translating it again.
• Byte Code (. pyc) will be shipped to PVM. It executes the code.

Syntax	At the end of the statement if you miss semicolon it throws an error. In Java you must define particular block using curly braces without it code won’t work.	In python, statement do not need a semicolon to end. In python, you have never seen a sight of curly braces but indentation is mandatory in python. Indentation also improves readability of code.
Dynamic	In java you must declare type of the data. class Example { public static void main (String [] args) { int x=10; System.out.println(x); } }	Python codes are dynamic typed. This means that you don’t need to declare a type of the variable this is known as duck typing. X = 45 site = “educba.com”
Speed	In terms of speed, Java is faster. Whenever in projects speed matters the java is best.	It is slower because python is an interpreter and also it determines the type of data at runtime.
portability	Due to the high popularity of Java, JVM (Java Virtual Machine) is available almost everywhere.	Python is also portable but in front of java, python is not popular.
Databases	(JDBC)Java Database Connectivity is most popular and widely used to connect with database.	Python’s database access layers are weaker than Java’s JDBC. This is why it rarely used in enterprises.
Easy to use	Java is not easy to use as compared to python because there is no dynamic programming concept and codes are longer than python.	Python codes are shorter than java. python follows dynamic programming python codes not only easy to use but also easy to understand because of indentation.
Practical Dexterity	Java enjoys more undeviating refactoring support than python thanks to its static type system and universality of IDE’s in development.	Python has always had an existence in the talent space and has the popularity for many reasons including Data Science and DevOps movement.
Legacy	Java’s history in the enterprise and its slightly more verbose coding style mean that Java legacy systems are typically larger and more numerous than python’s.	Python has less legacy problem so organization finds difficulty for the script to copy and paste codes.

Conclusion – Java vs Python

From above discussion, we can conclude that both Java and Python languages have their own benefits. It really is up to you to opt particular language for your project. Where Python is simple and succinct, Java is quick and more portable. While Python codes are dynamically-coded, Java is statically-coded. Python’s future is very glaring from where we see and presume that its future is assertive. Python is far from perfect but if we say that python is future and emerging language than we have to agree that Java is present, it’s API’s are widely used.

Both Java and Python are powerful in their own areas. Both Java and Python languages are related to accessibility, so companies, departments, and developers are best to keep a mind open when it comes to taking a decision.
