Java vs Python: Which is best? Comparison

Java vs Python Comparison: both are very powerful languages in the current programming language market. They both have many similarities and also they are battling to get the top position in the programming language market.

Python appeared first in the market even before Java was released but Java got more popularity and diplomacy from developers from the beginning. Python is one of the Top 10 most popular and fastest-growing programming language along with competitor Java. From few years Python got incredible success and becoming popular among developers.

According to Github’s annual Octoverse reports, Java and Python are the second and third most popular programming languages from four years in a row.

Key differences and specifications

  • Java is complex and not easy to learn while Python is easy to learn and use it because it’s used English-like syntax.
  • performance comparison: Java has very good performance compared to Python, Python is slower in various implementations.
  • Java and Python both are object-oriented programming languages.
  • Java uses static types while Python uses dynamic types, So every time you define a variable in java you must have to tell the interpreter its data type explicitly for eg. String, Array, Int, etc. and the other hand side in Python interpreter will automatically infer variables datatypes.
  • Java uses enclosing of braces while Python doesn’t use enclosing of braces which makes easy to understand the code.
  • You must have to put semicolumn after each statement of java while Python doesn’t need semicolumn to understand the end of the statement.
  • Java uses Spring and Blade for backend frameworks while Python uses Django and Flask.

Java vs python syntax comparison

Let’s take a look into python vs java code comparison. These simple programs will make you more clear to understand.

The Fibonacci series code in Java

public class Fibonacci {
       public static void main(String[] args) {
              int n = 10, a = 0, b = 1;
              System.out.print("First " + n + " terms: ");
              for (int i = 1; i <= n; ++i)
                  System.out.print(a + " ");
                  int sum = a + b;
                  a = b;
                  t2 = sum;


The Fibonacci series code in python

def fib(n):
     a, b = 0, 1
     while a < n: 
         print(a, end=' ')
         a, b = b, a+b


0 + 1 + 1 + 2 + 3 + 5 + 8 + 13 + 21 + 34 +
