This comparison on Java vs Python will provide you with a crisp knowledge about both the programming languages and help you find out which one fits your goal better. Java and Python are two of the hottest programming languages in the market right now because of their versatility, efficiency, and automation capabilities. This Java vs Python blog will provide you with a complete insight into the languages in the following sequence:

Let’s go back in time and look at the origin of both the languages and find out if Python is similar to Java.

History of Java & Python

Java is an object-oriented language with a C/C++-like syntax that is familiar to many programmers. It is dynamically linked, allowing new code to be downloaded and run, but not dynamically typed.

Python is the older of the two languages, first released in 1991 by its inventor, Guido van Rossum. It is a readable, efficient and powerful high level language with automatic memory management.

Comparison Factors

What is the difference between Python & Java? Both the languages have similarities and differences which makes it more difficult to select one out of the two. The most common question asked by the programmers is that if Python is better than Java. So let’s begin the comparison and find out the winner in Java vs Python.

Let’s look at the factors we will be using for the comparison on Java vs Python:

    The Table shows that Python has a slight edge over Java but let’s dwell in to the details of the comparison factors and find out which programming language is better.

    Java vs Python | Edureka

    Speed

    speed - Java vs Python - Edureka

    In terms of speed, Java is faster than Python as it is a compiled language. It takes less time to execute a code.

    Speed - Java vs Python - Edureka

    Python is an interpreted language and it determines the type of data at run time which makes it slower comparatively.

    Legacy

    Legacy - Java - Edureka

    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.

    Legacy - Python - Edureka

    Python has less legacy problem so organization finds difficulty for the script to copy and paste codes and gives it a slight edge over the other languages.

    Another confusion that arises when we talk about the two languages is that which one is easier between Java & python. So let’s have a look at the number of lines required while writing a code in both the languages.

    Code

    Code - Java - Edureka

    Java is very verbose as compared to Python. It takes 10 lines of code to read from a file in Java.

    Code - Python - Edureka

    It only takes 2 lines of code in Python. This makes Python a more preferable language.

    python scope - python vs c++ - edureka

    Java enjoys more undeviating refactoring support than python thanks to its static type system and universality of IDE’s in development. It is more popular for mobile and web applications.

    c++ scope - python vs c++ - edureka

    Python has always had an existence in the talent space and is considered to be the most favorable language for Machine Learning, Artificial Intelligence, IoT and a lot more.

    Trends

    India

    Trends - India - Edureka

    While not as trendy as it once was, Java is still the most popular programming language by virtually any measure. On the other hand, Python’s growth has been astronomical, especially in developed, high-income countries.  The reasons for this amazing growth include developer productivity, language flexibility, library support, community support, and ease of learning.

    Salary

    Average Salary - Java vs Python - Edureka
    Salary for Freshers - Edureka

    Now most of us are wondering if Python is going to replace Java in the recent times. When 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 the recent times. Nowadays, the jobs are mostly related to automation and artificial Intelligence which Prefer Python over Java and that’s why we can see the shift in the graph.

    Salary for Experience - Edureka

    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. The experience engineers find it convenient for them to stick to their comfort zone instead of moving to a new language.

    Syntax

    Number of Lines

    
    public class HelloWorld {
    
    public static void main(String[] args) {
    System.out.println("Hello, World");
    }
    
    }
    
    
    
    print ('Hello, World!')
    
    

    Semicolon

    
    class programming {
    
    programming() {
    
    system.out.println("Constructor method called");
    
    }
    
    public static void main(String[] args) {
    
    programming object = new programming();
    
    }
    
    }
    
    
    
    class Student:
    
      def __init__(self, name):
    
         print("This is parameterized constructor")
    
         self.name = name
    
      def show(self):
    
         print("Hello", self.name)
    
    student = Student("Daniel")
    
    student.show()
    
    

    Indentation

    
    class Greater {
    
    public static void main (String args[]) {
    
    int a = 10;
    
    if (a>0) {
    
    system.out.println("a is positive");
    
    }
    
    else {
    
    system.out.println("a is not positive");
    
    }
    
    system.out.println("This is executed");
    
    }
    
    }
    
    
    
    a=200
    
    b=300
    
    if b > a:
    
      print("b is greater than a")
    
    elif a==b:
    
      print("a and b are equal")
    
    else:
    
      print("a is greater than b")
    
    

    Read File

    
    import java.io.*;
    public class ReadFromFile2
    {
    public static void main(String[] args)throws Exception
    {
    File file = new File("C:UsersdanielDesktoptest.txt");
    
    BufferedReader br = new BufferedReader(new FileReader(file));
    
    String st;
    while ((st = br.readLine()) != null)
    System.out.println(st);
    }
    }
    
    
    
    > f = open("test.txt",'r',encoding = 'utf-8')
    >>> f.read()
