History of Java
• Java was developed in 1991 by James Gosling at Sun
Microsystems to be used as a solution for household
appliances such as remote control, microwave
oven,… But it is not interesting to market.
• Java is C/C++ based language.
• When the World Wide Web become popular in 1995,
Java come to life again.
• Java is now consider as native language of the
internet.
• Java is a full Object Oriented Programming

•
Simple: not support pointer, operator overloading
Object-Oriented: use object when run time
Statically type: must declare before use and object
Compiled: must compile before run source code
Architecture neutral and portable: platform independent
Multithreads: multitasking supported.
Garbage collected: auto release object from memory
Robust: preventing system crash when error
Secure: strict access area of system
Extensible: can access native method of C++
Java 2 software Development kit
• Java API for develop java program has:
– JDK7
• IDE helps to develop a java program:
– Borland JBuilder
– NetBean
– JCreater
– Visual Café
– TextPad
Java Virtual Machine
How to write java source code
syntax:
Package Name;
Import PackageName;
public class ClassName
{
public static void main(String[ ] arg)
{
Block statement
}
}
Example
File Name:Test.java
public class Test
{
public static void main(String[ ] arg)
{
System.out.println(“Hello Java”);
}
}
Install and use IDE
• Install NetBean
– Download JDK and NetBean from web site
http://www.oracle.com/technetwork/java/javase/downloa
ds/index.html
– Install JDK
– Adding JDK Path to environment variable(Optional)
– Install NetBean
• NetBean Management Tools:
–
–
–
–
Create project
Create Package
Create Class
Compile and Run Java source code
