4. History of
C Programming Language
 Development purpose: re-implement UNIX operating
system
 Developed by: Dennis Richie
 Developed at: AT & T Bell labs
 Development year: 1972
 Features: Structured or procedure oriented
 Limitation: not suitable to represent and solve most of
the real world problems
 Influenced to : CPP, Objective C, etc

5. History of
C++ Programming Language:
( C with classes) ( Increment of C)
 Development purpose: to represent real world entities and
solve real world problems efficiently
 Developed by: Bjarne Stroustrap
 Developed at: AT & T Bell labs
 Development year: 1978
 Features: Object oriented programming language
 Limitation: Binary platform dependent
Explicit pointers,
No garbage collection,
Everything is not part of object
 Influenced to : Java, C# etc

6. History of JAVA
 Development purpose: to write code for Consumer electronic
devices
to Write Once Run Anywhere (WORA)
 Developed by: James Gosling
 Developed at: Sun Microsystems
 Development year: 1994
 Features: Object oriented programming language
 Influenced to : ECMA Script, Java Script, PHP, Python, and
Embeded Java etc.,
Goal:
• To implement a virtual machine which is much simpler than
C/C++.
• Java was developed with the goal to implement
“Write Once, Run Anywhere” (WORA)
programming model.

7. (contd..) History of JAVA
• The history of java starts from Green Team.
• Java team members also known as Green Team.
• They initiated a revolutionary task to develop a
language for digital devices such as set-top boxes,
televisions etc.
• It was an advance concept at that time.
Currently,
Java is used in internet programming, mobile
devices, games, e- business solutions etc.

8. Java Evolutions
 1990- Sun Microsystems decided to develop a special
software , that could be used to manipulated consumer
electronic devices.
 A team, headed by James Gosling undertake this project.
 1991- After exploring the possibility of using most
popular Object oriented language C++, the team
announced a new language name “Oak”.
 1992- The team demonstrated the application of their
new language to control a list of home appliances using a
hand-held device.
 1993- WWW (World Wide Web) appeared on the Internet
 1994- The team developed web browser “Hot Java” to
locate and run applet programs on Internet.
 1995- The new language “Oak” named as JAVA, due to
some legal problems.

9. Initially developed
by
James Gosling
at
Sun Microsystems
and
released
in
1995.

10. Why Oak?
Oak is a symbol of strength
It is a national tree of many
countries like the U.S.A., France,
Germany, Romania, etc.
In 1995, Oak was renamed as "Java"
because
it was already a trademark by Oak
Technologies.

11.  The original name of the programming language was Oak.
 Later on, it was discovered that there is already a programming language
named Oak.
 The team gathered to choose a new name.
 The suggested words were "dynamic", "revolutionary", "Silk", "jolt", "DNA",
etc.
 After a lot of discussions, the development team took a break and went
out for Coffee.
 That’s where the name “Java” was proposed and finalized by
the team.
 According to James Gosling,
 “Java was one of the top choices along with Silk".
 Since Java was so unique, most of the team members preferred
Java than other names.
Java is just a name, not an acronym.
How Java got its name?

12. Tools You Need
 a Pentium 200-MHz computer with a minimum of 64 MB
of RAM (128 MB of RAM recommended).
Software's −
 Linux 7.1 or Windows xp/7/8 operating system
 Java JDK 8
 Microsoft Notepad or any other text editor

13. What is
Java? Java is a computing platform for application development
and an object-oriented,
 Class-based and Concurrent programming language
 It means many statements can be executed at the same time
instead of sequentially executing it.
 Java can run on all platforms and free to access.
 Important points:
 It is platform-independent
 i.e., java code can be compiled on any operating system
 It supports concurrency
 means the code can be executed by multiple processes at
the same time.

14. Java Applications
 According to Sun, 3 billion devices run Java.
 There are mainly 4 types of applications
1. Standalone Applications
 Also known as desktop applications or window-based applications.
 These are traditional software i.e., we need to install on every machine.
Examples Acrobat reader Media player, antivirus, etc.
2. Web Applications
 An application that runs on the server side and creates a dynamic page is
called a web application.
 Currently, Servlet, JSP, Struts, Spring, Hibernate, JSF, etc. technologies are used for creating
web applications in Java.
Example: irctc.co.in, google.com, etc.
3. Enterprise Applications
 An application that is distributed in nature, such as banking applications, etc.
is called enterprise application.
 It has advantages of the high-level security, load balancing, and clustering. In
Java,
Example: banking applications.
4. Mobile Application
 An application which is created for mobile devices is called a mobile
application.
 Currently, Android and Java ME are used for creating mobile applications.
