Difference between Java and JavaScript

Hello guys, Before we start discussing the differences between Java and the JavaScript, let's first briefly know about what Java and JavaScript are. Then, afterward, we will see the differences between both and their programming implementation.

What is Java?

Java is an object-oriented programming language (OOP), and it has so many powerful features that make Java one of the most popular, useful, and high-performance programming languages. Java is widely recognized for its object-oriented platform independence, high performance, security, etc.

Java was developed by James Gosling at Sun Microsystems in the year 1995 and later on Oracle Corporation's acquisition of Sun Microsystems in 2009–10.

Java syntax and concepts are easy and simple to learn and understand. That makes Java a simple programming language. Java's syntax is similar to other programming languages like C and C++. The codes in Java are always written in the form of classes and objects.

What is JavaScript?

JavaScript (often abbreviated JS) is a programming language, developed by Netscape, Inc. JavaScript is one of the core technologies that is used both on the client-side and server-side.

JavaScript is a high-level, often just-in-time compiled language that conforms to the ECMAScript standard. It has dynamic typing, prototype-based object orientation, and first-class functions. It is multi-paradigm, supporting event-driven, functional, and imperative programming styles. It has application programming interfaces (APIs) for working with text, dates, regular expressions, standard data structures, and the Document Object Model (DOM).

JavaScript can be used to develop web applications, mobile applications, gaming applications, build web servers, etc.

Java was developed by James Gosling at Sun Microsystems.	JavaScript was developed by the "Netscape."

Java is an object-oriented programming language.	JavaScript is an object-based scripting language.

Java is a strongly typed language.	JavaScript is a weakly typed language.

Java file extension is .java	JavaScript file extension is .js

Java program must be compiled on the server before executing.	JavaScript code are all in text, interpreted by the client (Browser).

Java occupies more memory to run the application.	JavaScript takes less than Java.

Java is a static language.	JavaScript is a dynamic language.

Java creates applets or stand-alone applications.	JavaScript does not create applets or stand-alone applications.

    public static void main(String args[]) {  
      System.out.println("Welcome to Java Programming World");  
    }  
  }

JavaScript Program Example

  <html>  
  <body>  
  <script type= "text/javascript">  
    document.write("Welcome to JavaScript Programming World");    
  </script>
