Java vs Node.js

Java:

Java is an object oriented programming language. It is also known as multi threaded language. It was designed by James gosling in the year 1995. We can also say that the father of java is James Gosling. It was owned by the sun micro systems.

We also have many features in the java programming language. The main feature of java is the platform independence. We can also define it as WORA principle. It means that Write Once Run Any where. It is mainly used for mobile applications , desktop applications , web applications and games etc.

In java we have the hard ware and also the soft ware environment in which we can run the program. Java also have a runtime environment known as Java Runtime Environment ( JRE ) and also an Application Programming Interface ( API ).

Java was developed by sun micro systems (now subsidary of oracle) in the year 1995. Before naming as java it is already named as oak which was already a registered company. 

Java is also known as the network – centric language of programming. In order to concurrency java uses the thread based model. In java the variables are in mutable type in default itself and also the java programming language will not support the lazy evaluation.

   Java programming language contains the static members and also this programming language will not support the concept of operator overloading. It also offers with or provides with the backward compatibility.

We write a huge code in java programming language where it becomes more readable. We also have different kind of frame works in java such as grails , spring , etc.

Features of java:

We also have many features in java programming language. The main features or some of the features of java are as shown below :

  • Simple
  • Object – oriented  programming language
  • Portable
  • Plat form independent
  • Secured
  • Robust
  • Architecture neutral
  • Interpreted
  • High performance
  • Multi threaded language
  • Distributed
  • Dynamic

There is also an automatic garbage collection in java programming language. Java is a best known for its security and it is also known as the secured box. There is also a translator in java. The translators used in java are compiler and the combination of interpreter with JIT compiler.

We can also define the java by using the following definition :

  • Java is the collection of Application Programming Interface ( API ) .
  • Application Programming Interface ( API ) is the collection of the packages.
  • Packages are the collection of the classes and the interfaces.
  • Where the interface is the collection of abstract methods and also the final static variables.
  • Where the classes are the collection of instance variables , constructors and the instance methods.

Applications of java:

We can also develop many applications such as web applications etc . by using the java programming language. Few of the applications that are based on java are as shown below :

  • Desktop application such as media player , anti virus etc.
  • Web application such as Javatpoint etc.
  • Enterprise application such as banking application.
  • Mobile applications
  • Robotic application
  • Smart card application
  • Embedded system
  • Games etc.

Let us see a small program using the java programming language using the following code as shown below:

Exampl:

import java.io.*;
class Demo
{
public static void main ( String args [ ] )
{
System.out.println ( “ Welcome to java “ );
} // main method
} // demo class

Output :

Welcome to java

Node.js:

We have many libraries or frame works in the java script programming language such as Node.js, Sails.js, Partial.js and Express.js etc. So one of the library or frame work of the java script programming language is Node.js . 

Node . js  is one of the library that is used for programming. And this programming language is mainly used to create or develop the run time applications. The first person who written the node.js library using the java script programming language is Rayn Dahl. And then it was developed or managed by the Joyent.

We can use the node.js as both the back – end and also the front – end developers. This helps the developers in building the applications such as web applications, mobile applications etc.

In the Node.js library we also have a flexibility of handling the server side where the user can request the packet as well as at the same time the user can access the data base.

There is an advantage of Node.js. The advantage is that the Node.js by using the Application Programming Interfaces ( API ‘ s ) and also connect to the libraries which were written in the other languages other than Node.js .

Inorder to run the Node.js we should install the npm whereas inorder to run  the java program it requires the Java Runtime Environment ( JRE ). We know that java is used to handle the large programs and also as complex programs whereas node.js is only used to handle the simple and easy programs and also the server based applications.

We should write the program in the Node.js command line interface and then  we should type the command that is required.

Let us see a small program using the java programming language using the following code as shown below :

Example:

console.log ( ‘ Welcome to node.js ‘ );

Output :

Welcome to Node.js
