This document summarizes a project on connecting a Facebook account to a Java program. It includes the history and features of Java, basic object-oriented programming concepts, how to pass command line arguments, and how to connect a database to the main program code. The project code section and connecting the database sections are left unfinished, with placeholding text indicating work remaining.

2. CONTENTS
 History of Java
 Features of Java
 Basic terms
 Principle of OOPS
 Command Line Arguments
 Code as follows
 How to execute the code
 Project code
 Connecting database to main code

3. HISTORY OF JAVA
 James Gosling, Mike Sheridan, and Patrick
Naughton initiated the Java language project
in June 1991.
 Earlier it was named as OAK.
 Java is a Object Oriented Programming
language.

4. FEATURES OF JAVA
 Platform Independent
 Robust
 Portable
 Architecture Neutral
 Secure

5. Basic terms-
Byte-code-
• Highly optimized set of instructions
JVM-
• Run time environment
JDK-
• Java Development Kit
 JRE-
• It contains set of libraries

6. Principle of Oops-
1) Encapsulation-
 Bind together code and data.
 Also known as protective wrapper.
2) Inheritance-
 One object acquires properties of another object.
 ‘Extend’ keyword is used.

7. Contd...
 Having ‘base class’ and ‘derived class’.
3) Polymorphism-
 Polymorphism is the ability of an object to take
on many forms.

8. COMMAND LINE
ARGUMENTS-
We can pass some values at the time of executing
java program from command line. These values
are passed to the main method as arguments.
Main method invocation by JVM.

9. Code as follows:
For example : if we want to pass three names as command line
arguments.
Then the code will be as follows-
public static void main(String args[])
{
for(int i=0;i<3;i++)
{
System.out.println(args[i]);
}}

10. How to execute the code-
javac “class_name”.java
java “class_name”
And the output will be there.

11. Introduction on Facebook

12. PROJECT CODE-

13. CONTD..

14. After creating main method-

15. Connecting database to the main
method-

16. You can access facebook by login into
www.facebook.com and this is what you
will see…

17. Conclusion-
 It’s a social network- It’s a great way to keep in
toch with friends and also new friends.
 Facebook allows you to share information and
photos.
