1) Model

2)View

3)Controller

Model : Java Bean is nothing but Model
A java program which contain business logic is called as Model Component

REGULAR JAVA COMMANDS USED IN DOS COMMAND PROMPT

COMMAND	USAGE
javac	TO COMPILE JAVA PROGRAMS,IT DISPLAYS ALL OPTIONS RELATED TO COMPILATION javac Welcome.java
java	TO RUN JAVA PROGRAMS,IT DISPLAYS ALL OPTIONS RELATED TO RUN THE PROGRAMS java Welcome java com.ram.Welcome(when we have .class file in the package)
javac -d	COMPILE THE PROGRAMS AND PLACED IN PACKAGE javac –d destinationpath sourcepath javac –d . Welcome.java (Package folder will create in current directory) javac –d C:\myfolder\java\bin C:\myfolder\java\src\Welcome.java
javap	TO KNOW THE DETAILS OF ANY CLASS,IT DISPLAYS ALL THE METHODS IN THAT CLASS AND implemented interfaces,extended classes also javap Welcome
javadoc	CREATE DOCUMENTATION TO THE JAVA CLASSES javadoc Welcome.java
jar	TO CREATE JAR FILES,WAR FILES,EAR FILES AND ALSO EXTRACT THESE FILES jar –cvf filename.jar(create) jar –cvf myjar.jar jar –cvf mywar.war jar –xvf myjar.jar(extract) jar –xvf mywar.war
set	TO SET THE ENVIRONMENT VARIABLES LIKE ”CLASSPATH”, “PATH” AND “JAVA_HOME” set JAVA_HOME=C:\Program Files\Java\jdk1.7.0_01; set PATH=C:\Program Files\Java\jdk1.7.0_01\bin; set CLASSPATH=servlet-api.jar; set CLASSPATH=servlet-api.jar;ojdbc14.jar; (CLASSPATH for more jars at a time) set CLASSPATH=%CLASSPATH%;hibernate3.jar; (set CLASSPATH to already existed CLASSPATH variable)

Java Features

* Java is a complete object oriented programming Language(Objet Oriented)

Object oriented programming concepts are:

->Class
->Object
->Inheritance
->Polymorphism
->Abstraction
->Encapsulation

* Java is a completely platform independent language,so once we develope the code we can run on any machine which has java jvm(Platform Independent)

* Java is easy language we can easily understand(Easy to learn)

* It's providing full security across net,There is no explicit pointers(Secutiry)

* We can develope large applications(High Performance)

* Java is a multi threaded language,Thread is like a seperate program executing concurently(Multi Threaded)

* We can carry the java bytecode to any platform easily(Portability)

* Java is a Robust,it means Strong,It follows strong dynamic memory management(Robust)

* Java is a both compiler and interpreted based language(Interpreted)
