Java and
Python is the two most trending and Powerful languages of recent times and it is
quite common to get confused when it comes to picking one out of the two.
Now the most common question asked by the beginners is which one is better Java or Python.
The number of programming languages used in production and day-to-day life has
seen enormous growth in the last decades now from those bustling numbers.
We are
going to narrow our focus to the two most popular languages that have created
quite a buzz among the developers as well as the beginners.
So let's
begin with a brief introduction of both the languages.
Java is one
of the most fundamental languages that produce software for multiple
platforms. In addition, the best thing is that it is machine independent and
can be written once and run anywhere. Python, on the other hand, is a simple easy
to read and high-level programming language, but the program mostly falls in love
with it because of the increased productivity that it provides both of these
have been the two most popular and controversial languages of the decade.
So let's
move ahead and take a look at the various aspects of comparison that will help
us to find an answer to the question which one is better out of the two now if
we take a look at the speed of java and python, the former is a statically the typed programming language, which makes it faster.
Where is
the later is an interpreter which determines the type of data at runtime thus
making it slower comparatively when it comes to Legacy Java history in the
Enterprise. And coding style of Java are typically larger and more numerous.
Where python
has less Legacy problem, which makes it difficult for the organizations to
copy and paste codes. Now both the languages are pretty simple and easy to
write but if we look at the length of both the codes python consists of fewer lines or shorter codes as compared to Java which is also easy to
understand. Another characteristic is the databases, Java database connectivity
is most popular and widely used to connect whereas pythons database access
layers are weaker than JDBC that is why it is rarely used in Enterprises.
Now if I
look at the Practical agility Java provides more undeviating refactoring
support then python because of its static type system and universality of IDE
for the development of mobile and web applications.
But python
has become a popular choice for all the recent Technologies, like data science,
machine learning, IoT and artificial intelligence. Next up, If we look at the
Search results of US and India in the last five years the US has seen a drastic drift
in the domination of both the languages, there has been significant growth in
the search for python whereas the other has seen a gradual decrease in the
graph.
India has
also seen a growth in the case of python. The next feature of comparisons is the
salary growth of Java Engineers and Python Engineers based on their experience.
We can see
that there has been a steady growth in both the situations over a certain
period of time. Now if we compare the growth of both the engineers in case of freshers,
Python has a little edge over Java due to its increased demand in recent
times nowadays. The jobs are mostly related to Automation and artificial
intelligence.
Whereas if
we look at the growth in case of experienced Engineers Java dominates over the
time because Java has been in use way before python became popular and the
experienced Engineers find it convenient for them to stick to their comfort
zone instead of moving to a new language.
Now, let us
have a look at one of the most important aspects that make Java and Python
different from each other and this might help you to finally decide the winner
out of the two. Let's have a look at some of the basic differences.
Java is a
compiled programming language, the source code is compiled down to bytecode by
the Java compiler, and the byte code is executed by a Java virtual machine. On
the other hand, Python is an interpreted language as the translation occurs at
the same time as the program is being executed. Now Java supports
Encapsulation, Inheritance, Polymorphism, and Abstraction, which makes it an
object-oriented language, python is also an object-oriented language, but it
has an added advantage. It is also a scripting language and it is easy to write
scripts in Python.
Now
statically typed programming languages do type checking at compile time as
opposed to run time. Whereas the dynamically typed programming languages do
type checking at runtime as opposed to compile-time and it helps you write a
little quicker because you do not have to specify types every time next if we
compare the number of lines in a code python can perform the same action with
fewer lines than the same code written in Java in this example.
We are
printing the statement hello world using both the languages but in Java, we
need to define a class and the main function, which makes it a 3-line code
already. Whereas we can just use the print function for the statement in case
of python. In Java programming language if you miss the semicolon at the end of
a statement, it will throw an error but there is no such need of any semicolon
to end the statement in case of python.
Now another
important difference in the syntax of both. The languages is the indentation in
Java. You must define a particular block using curly braces. Otherwise, the
code won't work. But in case of Python there is no such sight of any curly
braces, even though indentation is mandatory. It also improves the readability
of the code. So if we take a closer look at all these aspects of comparison, we
can say that Python has a slight edge over Java and it would be fair to declare
the former as the winner in this battle.
So, what do
you think do let us know about your opinion in the comment section below and
mention other aspects where you think Java wins over Python until then?
Thank you
