Java Tutorial

Our center Java programming instructional exercise is intended for understudies and working experts. Java is an article arranged, class-based, simultaneous, verified and universally useful PC programming language. It is a generally utilized hearty innovation

What is Java

Java is a programming language and a stage.

Java is an abnormal state, hearty, object-situated and secure programming language.

Stage: Any equipment or programming condition in which a program runs, is known as a stage. Since Java has a runtime domain (JRE) and API, it is known as a stage.

Java Example

How about we have a fast see Java programming precedent. A point by point depiction of hi Java precedent is accessible in next page.

class Simple{      public static void main(String args[]){       System.out.println("Hello Java");      }  }

Application

As per Sun, 3 billion gadgets run Java. There are numerous gadgets where Java is presently utilized. Some of them are as per the following:

1. Desktop Applications such as acrobat reader, media player, antivirus, etc.
2. Web Applications such as irctc.co.in, javatpoint.com, etc.
3. Enterprise Applications such as banking applications.
4. Mobile
5. Embedded System
6. Smart Card
7. Robotics
8. Games, etc.

Types Of Java Applicaion

There are mainly 4 types of applications that can be created using Java programming

1)      Standalone Application

Independent applications are otherwise called work area applications or window-based applications. These are customary programming that we have to introduce on each machine. Instances of independent application are Media player, antivirus, and so on. AWT and Swing are utilized in Java for making independent applications.

2)      Web Application

An application that runs on the server side and creates a dynamic page is called a web application. Currently, Servlet, JSP, Struts, Spring, Hibernate, JSF, etc. technologies are used for creating web applications in Java.

3)      Enterprice Application

An application that is disseminated in nature, for example, banking applications, and so on is called endeavor application. It has favorable circumstances of the abnormal state security, load adjusting, and bunching. In Java, EJB is utilized for making endeavor applications.

4)      Mobile Application

An application which is made for cell phones is known as a portable application. Presently, Android and Java ME are utilized for making versatile applications.

Java Platform/Editions

There are 4 platforms or editions of Java:

1)      Java SE (Java Standard Edition)

It is a Java programming stage. It incorporates Java programming APIs, for example, java.lang, java.io, java.net, java.util, java.sql, java.math and so forth. It incorporates center points like OOPs, String, Regex, Exception, Inner classes, Multithreading, I/O Stream, Networking, AWT, Swing, Reflection, Collection, and so on.

2)      Java EE  (Java Enterprise Edition)

It is an endeavor stage which is primarily used to create web and venture applications. It is based on the highest point of the Java SE stage. It incorporates points like Servlet, JSP, Web Services, EJB, JPA, and so forth.

3)      Java ME (Java Micro Edition)

It is a small scale stage which is for the most part used to create portable applications.

4)      Java FX
