What is JAVA ?

“ Java From 10,000 Feet's  According to the world, Java is...  According to Sun, Java is...  On closer inspection, Java is

“ According to the World, java is...  Secured Web pages  The cross-platform language  The rest-of-the-worlds answer to Bill Gates  The C++ replacement we need  A bunch of hype

According to Sun, JAVA IS...  Simple and Powerful  Object Oriented  Portable  Architecture Neutral  Distributed  Multi-threaded  Robust, Secure/Safe  High Performance

On Closer Inspection, JAVA IS...  Simple  Pure  Portable  Surprisingly effective

Why Java ?

“ Java Write Once, Run Anywhere

“ Security Models In JAVA  Need For JAVA Security.  The Sandbox Model or Java 1.0.  Java 2 Platform Security Model.

Need For Security IN JAVA  Code Mobility Can Be Useful. * Improve Functionality of Services.  Downloaded Executable Contents is Dangerous * The Source May Be Unknown Hence Trusted. * Downloaded Code May modify or destroy data in our System. * They may be install other hostile code on our system. * Hostile code may use the resources of our system.

Sandbox model  The original security model provided by the Java platform.  It existed in order to provide a very restricted environment in which to  run untrusted code obtained from the open network.

Java 2 Platform Security Model

“  Fine Grained Access Control :- * Every code access to the resources based on what is defined in a policy file.  Easily Configurable Security Policy :- * It is desirable to allow application builders and users to configure security policies without having to program.  Easily Extensible Access Control Structure :- * The new architecture allows typed permissions and automatic handling of all permissions of the correct type.  Extension of Security Checks to all Java programs :- * There is no longer a built-in concept that all local code is trusted.

“ How Sandboxing work ?  Compile the Applet.  Create JAR file for the Applet.  Generate a pair of public/private keys.  Sign the applet jar with private key.  Export the certificate for public key.  Import the certificate as a trusted certificate.  Create the policy file.  Load and run the Applet.

Performance of java

Twitter migrates core infrastructure to the JVM and supports more than 400 million Tweets a day.

Java's innate scalability has played a key role in enabling Netflix to expand its service to more than 57 million members in 50 countries. Collectively, these viewers enjoy more than 1 billion hours of shows and movies per month.

JAVA IN REAL WORLD  1.1 billion desktops run Java.  930 million Java Runtime Environment downloads each year.  3 billion mobile phones run Java.  10 times more Java phones ship every year than Apple and Android combined.  100% of all Blu-ray players run on Java.  1.4 billion Java Cards are manufactured each year.  Java powers set-top boxes, printers, Web cams, games, car navigation systems, lottery terminals, medical devices, parking payment stations, and more.

“ Tiobe & pypl  TIOBE Index : TIOBE ratings are calculated by counting hits of the most popular search engines.  PYPL Index : The PYPLU Popularity of Programming Language Index is created by analyzing how often language tutorials are searched on Google.

TIOBE Index for 2018

Very Long Term History

PYPL Index for 2018

“ How many Java developers ? Based on a survey made using various portals, different sources for estimation – popularity contests, job market analysis and download numbers of popular Java development infrastructure products there are approximately 8,311,000 Java developers in the World.
