Programming languages are essential for every programming activity; even if they are basic tools in a programmer’s toolbox. we can say that programming languages are a fundamental part of computer science. At present, python vs java is the two most popular and competitive programming languages. Both are battling for getting top positions in the topmost popular programming languages.
Many beginners are confused about python vs java. We are going to discuss all the essential differences between python vs. java. This blog will be helpful for you to understand the comparison between them.

What is python
The early development of python is early starts at a research institute in the Netherlands. The main purpose behind the development of python is to make a high-level language that can bridge the gap between the shell and C. Python is one of the dynamically-typed general-purpose programming languages.
What is java
It is one of the general-purpose programming languages. It is used mostly for developing a wide range of different applications from the web to enterprise to mobiles etc. Java is designed as a programming language that can run on any platform. Along with few dependencies as possible.
Python vs Java in code
Let’s see how Java and Python work differently.
Syntax
Because Python is an interpreted language, its syntax is more concise than Java, making getting started easier and testing programs on the fly quick and easy. You can enter lines right in the terminal, where Java must compile the whole program to run.
Type python and then 3+2, and the computer responds with 5.
Python
3+2
5
Consider doing this with Java. Java has no command line interpreter (CLI), so to print five as we did above, we have to write a complete program and then compile it. Here is Print5.java:
public class Print5 {
public static void main(String[] args) {
System.out.println(“3+2=” + (Integer.toString(3+2)));
}
}
To compile it, type javac Print5.java and run it with java Print5.
java Print5
3+2=5
With Java, we had to complete a program to print 5. That includes a class and the main function, which tells Java where to start.
We can also have a main function with Python, which you usually do when you want to pass it arguments. It looks like this:
def main():
print(‘3+2=’, 3+2)
if __name__== “__main__”:
main()
Classes
Python code runs top to bottom—unless you tell it where to start. But you can also take classes, like possible with Java, like this:
Python Class
class Number:
def __init__(self, left, right):
self.left = left
self.right = right
number = Number(3, 2)
print(“3+2=”, number. left + number. right)
The class, Number, has two member variables, left and right. The default constructor is __init__. We instantiate the object by calling the constructor number = Number (3, 2). We can then refer to the variables in the class as numbers. Left and Number.
Right. Referring to variables directly like this is frowned upon in Java. Instead, getter and setter functions are used, as shown below.
Here is how you would do that same thing In Java. As you can see, it is wordy, a prominent complaint people have with Java. Below we explain some of this code.
Java Class with Getter and Setter functions
class PrintNumber {
int left;
int right;
PrintNumber(int left, int right) {
this.left = left;
this.right = right;
}
public int get left() {
return left;
}
public int GetRight() {
return right;
}
}
public class Print5 {
public static void main(String[] args) {
PrintNumber print number = new PrintNumber (3,2);
String sum = Integer.toString(printNumber.getleft()
+ printNumber.getRight() );
System.out.println(“3+2=” + sum);
}
}
Python is gentle in its treatment of variables. For example, it can print dictionary objects automatically. With Java, it is necessary to use a function that explicitly prints a dictionary. Python also casts variables of one type to another to make it easy to print strings and integers.
On the other hand, Java has strict type-checking. This helps avoid runtime errors. Below we declare an array of Strings called args.
String[] args
You usually put each Java class in its file. But here, we put two types in one file to simplify compiling and running the code. We have:
class PrintNumber {
int left;
int right;
}
That class has two member variables, left and right. In Python, we did not need to declare them first. We just did that on the fly using the self-object.
In most cases, Java variables should be private, meaning you cannot refer to them directly outside the class. Instead, you use getter functions to retrieve their value like this.
public int get left() {
return left;
}
So, in the main function, we instantiate that class and retrieve its values:
public int get left() {
return left;
}
public static void main(String[] args) {
PrintNumber print number = new PrintNumber (3,2);
String sum = Integer.toString(print numberer. get left ()
+ print number.getRight() );
}
Where Python is gentle in its treatment of variables, Java is not.
For example, we cannot concatenate and print numbers and letters like “3+2=” + 3 + 2. So, we have to use the function above to convert each integer to a string Integer.toString() and then print the concatenation of two strings.
Popularity
Java and Python are two of the multiple popular programming languages. Java is the faster language of the two, but Python is simpler and easier to learn. Per is well-established, platform-independent, and part of a large, supportive society.
History of python vs java
If you want to understand the difference between python vs java, first of all, you need to know about histories in brief
| Python | Java |
| Python is one of the two languages that were released by Guido Van Rossum in 1991. Python is one of the most efficient, powerful, and easily readable high-level languages. Python is one of the most popular programming languages in the last few decades. | Java is a concurrent and object-oriented language with C and C++ programming languages. Java is familiar to most programmers, like syntax. Java is a dynamically linked programming language, that allows programmers’ new code to be downloaded and run. But still, Java is not a dynamically typed language. |
Some important difference between Python vs Java
The basis of the difference | Python | Java |
| Easy to use | Python is one of the easy-to-use and learn programming languages. | Java is also easy to learn and use, but it is not easier than python. |
| Speed | Python only tracks the data type at run time. That makes it comparatively slower than java. | As java always takes less time to execute code. Hence in terms of speed, It is comparatively faster than python. |
| Static or Dynamic | Python programming language that is Dynamically typed | Java programming language is statically typed. |
| Trending language | Python is one of the most trending languages. | Java is not a much-trending language according to others. |
| Syntax | Python is one of the straightforward programming languages. That is why it is easy to use. | Java is not a straightforward language but it’s one of the complex programming languages. |
| On the basis of Legacy | The legacy problems in python are lesser than java’s. | The legacy system of java is typically more and larger than python’s. |
| Code | The main reason that python is a more preferable programming language is that it only takes two lines of source code in python( to read a file in python). | Everyone knows that Java is more verbose comparably to python. Hence it takes ten lines of source code in java( to read a file from java). |
| Practical Agility | From the beginning python always has beings in existence with the talent space. Python is mostly considered a preferable language for artificial intelligence, all types of machine learning, IOT and a lot more. | Java is mostly popular for many web applications and for mobiles. Because of its universality of IDE’s in developments, and statics type system It’s more preferable than python. |
| Architecture | Python doesn’t itself translate codes into machine language. But the interpreter translates all coding language into machine-independent bytecode language for python. | The java virtual machine provides the runtime environment to execute the codings and convert different bytecodes into the machine language. |
| Database support | Python offers very slow connectivity compared to java. | Java always provides stable connectivity to all areas of the globe. |
