History of java
• Author of java – James Gosling
• Home - Sun Micro System
• First version launch - 1996,jan 23
• Used version - java5 other java6,java7
• Latest version - java 8
• Type of software - open source software

Introduction of java
Java is a technology which running on any type of
os,ios etc .Java developer develop both type of
software application Standlone and Distributed .
Standlone application –system based.
Distributed Application – client based.
Java divided into three part
J2se ( core java , jdbc ( database connectivity ) ).
J2ee (adv. Java ) .
J2me (mobile ,android ).

Formate of java program
i. Comment
ii. Project Name
iii. Package Name
iv. Class Name
v. Main class Name
Example
Helloo
Java.lang.*;
class
{
Public static void main(string args[])
{
System.out.println(“Hii frnds”);
}
}

Compilation and running phase
Above program save helloworld.java
Hello.java
Compilation phase -
Hello.class
Running phase  Machine language
Bytecode
 Assemply lan.
hello.class

Why java plateform independent
because of bytecode
Application of java

Indroduction advance java
Adv. Java introduce for making server side application
& web-application.
Ex. Gmail.com,require information fetching from Database,etc.
Adv. Java divided in to two part
i. Servlet (required Processing logic then go for )
ii. JSP (required Presentation logic then go for )
Current version of JEE is 7.0v
Current version of Servlet is 3.1v;
Current version of JSP is 2.3v

Format of advance java program with example
Adv. Java program save .java
Folder structure of adv. Java program
adv1
WEB-INF
=>web.xml
=> classes
hello.java / hello.class

Example
import java.io.*; I
mport javax.servlet.*;
import javax.servlet.http.*;
class public class HelloWorld extends HttpServlet
{
private String message;
public void init() throws ServletException
{
message = “today date ";
}
public void doGet(HttpServletRequest request, HttpServletResponse response) throws
ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<h1> message " + new Date + "</h1>");
}
public void destroy() { }
}

Servlet is go on why coming jsp technology
Write a small program in servlet then write no of line
of code but jsp same program write in 1/3rd line of
code.
Example
<html>
<head>
<title>Hello World</title>
</head>
<body> Hello World!<br/>
<p>Today's date: <%= new java.util.Date()%></p></body>
</html>

Introduction SpringFramework
HOME  Interface 21.
AUTHOR  Rod Jonson.
TYPE  Open Source s/w.
TYPE OF FRAMEWORK  Application Framework.
INITIAL-VERSION  Spring 1.0 (OCT 2004).
LATEST-VERSION Spring 4.3.8(APRIL 2017).
Spring is the most popular application development framework for enterprise Java.
Millions of developers around the world use Spring Framework to create high
performing, easily testable, and reusable code.
Spring framework is an open source Java platform. It was initially written by Rod
Johnson and was first released under the Apache 2.0 license in June 2003.
The Spring Framework is a lightweight solution and a potential one-stop-shop for
building your enterprise-ready applications
