Introduction

• Our Java Tutorial or Core Java Tutorial or Java
  Programming Tutorial is intended for understudies
  and working experts. Java is a question arranged,
  class-based, simultaneous, broadly useful
  computer-programming language and generally
  utilized strong technology. How about we begin
  taking in Java from basic inquiries like what is
  Java, Core Java, where it is utilized, what kind
  of applications are made in Java, why utilize
  Java and Java platforms and so on. Our Java
  instructional exercise encourages you to learn
  Java with simple and straightforward cases.

What is Java ?

• Java is a programming language and a platform.
• Java is an abnormal state, powerful, secure and
  question situated programming language.
• Platform Any equipment or programming condition
  in which a program runs, is known as a platform.
  Since Java has its own particular runtime
  condition (JRE) and API, it is called platform.

Where it is utilized

• As indicated by Sun, 3 billion gadgets run java.
  There are numerous gadgets where Java is as of
  now utilized. Some of them are as per the
  following
• Work zone Applications, for instance, gymnastic
  entertainer peruser, media player, antivirus et
  cetera.
• Web Applications, for instance, irctc.co.in,
  javatpoint.com et cetera.
• Enterprise Applications, for instance, keeping
  cash applications.
• Mobile
• Installed System
• Keen Card
• Mechanical independence
• Recreations et cetera.

Different Kinds of Java Applications

• There are for the most part 4 kinds of
  applications that can be made utilizing java
  programming
• 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. Case
  of independent applications are Media player,
  antivirus and so on. AWT and Swing are utilized
  as a part of java for making independent
  applications.

• Web Application
• An application that keeps running on the server
  side and makes a dynamic page, is called web
  application. At present, servlet, jsp, swaggers,
  spring, sleep, jsf and so on advances are
  utilized for making web applications in Java.
• Enterprise Application
• An application that is circulated in nature, for
  example, keeping money applications and so on is
  called enterprise application. It has the upside
  of abnormal state security, stack adjusting, and
  bunching. In Java, EJB is utilized for making
  enterprise applications.
• Mobile Application
