What is the Difference Between Java and Python? with Proper Definition and Brief Explanation

The main difference between Java and Python is that the Java compiler converts the Java source code into an intermediate code called bytecode while the Python interpreter converts the Python source code into a machine code line by line.

Java is a programming language designed for use in a distributed environment. It is a popular programming language for various applications such as Android smartphones and the Internet of Things (IoT). The concept behind Java is “write once, read anywhere”. On the other hand, Python is a simple and easy to use programming language, which is useful for building web applications, scientific and numerical computing, machine learning, image processing, data analysis, and many more.

What is Java

Java is a popular high-level programming language. Web applications, mobile applications, high-performance distributed systems are some examples of Java-based applications. Also, Java has many versions; Java SE is the standard edition. Java ME is for mobile development, while Java EE is for enterprise-grade applications. In addition, there are integrated development environments (IDE) with all the necessary tools to develop applications in Java. Some common Java IDEs are NetBeans and Eclipse.

Furthermore, Java is a programming language that supports object-oriented programming, which allows modeling real-world scenarios in computing. However, Java source code is not directly converted to machine code. First, the source code is converted into an intermediate code: bytecode. This bytecode is executable on any platform consisting of a Java Virtual Machine (JVM). Therefore, Java is platform independent. In addition, it provides error handling, compile-time error checking, and run-time error checking. Furthermore, it is also possible to implement multi-threading and allows to develop secure applications.

What is python

Python is a high-level programming language. It is a multi-paradigm language and supports both procedural programming and object-oriented programming. Also, an interpreter converts Python source code into machine code line by line. However, it is a slow process compared to a compiler-based language that converts all source code to machine code at once.

However, the main advantage of the Python language is that it is simple and easier to learn. Therefore, it is one of the most popular languages ​​among beginners. Simple syntax helps to develop even a complex algorithm to solve a problem in a short period of time.

Also, it is easier to integrate with databases like MySQL, MSSQL and SQLite. In addition, it allows you to develop graphical user interfaces (GUI). Also, it supports multithreading.

Similarities Between Java and Python

  • Both are high level general purpose programming languages.
  • The developer can easily download and install both without paying a fee.
  • Furthermore, it is possible to integrate it with databases such as MySQL and MSSQL.
  • Also, both support GUI and multithreaded development.
  • These two languages ​​can be used for a variety of applications, including web, mobile, machine learning, image processing, etc.

Difference between Java and Python


Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. On the other hand, Python is a high level interpreted programming language for general purpose programming. Hence, this is the main difference between Java and Python.

Code Conversion

Also, code conversion is an important difference between Java and Python. The Java compiler converts Java source code into intermediate code called bytecode. Conversely, the Python interpreter converts the Python source code into machine code line by line.

Type of data

In Java, it is mandatory to declare the data types, so it is typed statically. In Python, data types are dynamic and data types do not need to be declared. Therefore, it is written dynamically. Hence, this is another important difference between Java and Python.


Also, Java requires a semicolon at the end of each statement. In Python, there is no need to use a semicolon at the end of statements.

Statement Block

In Java, a pair of braces surrounds a block of declarations. However, in Python, a statement block is indented.


Also, Java is a faster language compared to Python.


Another difference between Java and Python is that Java is a difficult language to learn while Python is easier to read, learn and understand.


NetBeans and Eclipse are popular Java IDEs, while PyCharm is a popular Python IDE.


The main difference between Java and Python is their conversion; the Java compiler converts Java source code into intermediate code called bytecode, while the Python interpreter converts Python source code into machine code line by line.
