ADVANCE JAVA
==> It is used to create a complete application.

==> By using Advance java we can create web application.

APPLICATION
The collection of programs is known as application.

==> We have 4 types of applications.

1. Stand Alone Application

2. Web Application

3. Mobile Application

4. Distributed Application

1.) STAND ALONE APPLICATION

==> The application which will work without internet is known as Stand Alone
Application.

==> To develop Stand Alone Application we require Core Java.

==> Stand Alone Applications are present in Client Machine (User System).

Example: Calculator, Notepad, EditPlus, Gallery, Music, Settings etc.

------------------------------------------------------------------------------------------------
NOTE:
Stand Alone Applications are known as Independent Applications.
------------------------------------------------------------------------------------------------
2.) WEB APPLICATION

==> The application which will work with internet and browser is known as
Web Application.

,==> To develop Web Application we require Web Technology and Advance
Java.

==> Web Applications are not present in Client Machine.

Example: Facebook, Myntra, Flipkart, Amazon etc.

------------------------------------------------------------------------------------------------
NOTE:
==> Browser is an application which is used to access Web Applications
by using Internet.
------------------------------------------------------------------------------------------------
COMPONENTS OF WEB APPLICATIONS

==> There are two components for Web Applications

1. Front-End

2. Back-End

1. FRONTEND

==> The elements which are visible to the user is known as Front-End of an
application.

==> To develop Front-End of an application we require Web Technologies.

2. BACKEND

==> The elements which are not visible to the user is known as Back-End of an
application.

==> To develop Back-End of an application we require Java, SQL.

TYPES OF WEB APPLICATIONS

==> There are two types of Web Application

1. Static Web Application

2. Dynamic Web Application

,1. Static Web Application

==> The application which contains only Front-End is known as Static Web
Application.

==> To develop Static Web Applications we have to use Web Technologies.

2. Dynamic Web Application

==> The application which contains only Front-End as well as Back-End is
known as Dynamic Web Application.

==> To develop Dynamic Web Applications we required Advance Java (which
includes Java, SQL and Web Technologies).

SERVER

==> Server is a machine which is used to store Web Application.

==> Servers are the mediator between Developer and User.

==> Developer is using the server to store the Web Applications.

==> User is using the server access Web Applications by sending Request and
Response.

3.) Mobile Application

==> The Application which needs to download and install in Mobile is known
as Mobile Application

==> Mobile Applications are developed by using FLUTTER Technology.

, ==> To use mobile applications in mobile we need Operating System.

Example: Android, IOS, Linux, Java

4.) Distributed Application

==> The applications which are interconnected is known as Distributed
Applications.

==> Distributed Applications are developed by using Cloud Technology.

Example: Google(Gmail,GMap,GDrive,GPhotos,Youtube),
Amazon(AmazonPay,Prime,Music,Shopping)
