Introduction …
Programming Language Paradigms
• A programming paradigm is a fundamental
style of computer programming. This means the
manner or approach used in the programming.
• Based on programming paradigms, programming
languages are broadly classified into two levels:
low-level languages and high-level languages.
• High-level languages are classified into four
programming paradigms: imperative, functional,
declarative and object-oriented. [1], [2]

Programming Language Paradigms
There are several key concepts in object-oriented programming (OOP):
• Data Abstraction
• Encapsulation
• Inheritance
• Polymorphism [3]

•
Java can't convert an int to a boolean value,
Java has no 8-bit unsigned byte,
Java has no first class methods,
Java has no pass by reference semantics,
Burn a CD/DVD,
Copy or move a file (with all metadata intact),
Raw console access; e.g. curses, clear screen, etc.
In general it lacks in low-level programming
(not designed to write OS, compilers, etc.)

Quota of Java in the Marketplace …
How Many Java Programmers in Saudi Market?
Based on a survey made by our team with
some companies in Riyadh, we conclude that
there is approximately 40% who use Java
language in the Saudi market.
Conclusion
 Java is a Leading Programming Language
 What’s Next: …
Conclusion …
Java is a Leading Programming Language
 Java is a powerful object-oriented paradigm language.
 Java is a platform that runs almost on any OS. For this
reason and others it is widely used nationally and
internationally whether in institutions or companies.
 Many corporations and business organizations adopt
Java for developing web & mobile based applications.
 Saudi market, like other markets in the world, use Java
as applications development language.
 Studying Java keeps you employed in both private and
public sectors in Saudi Arabia market.
Conclusion …
What is Next: …
 Java 7 is released in 2011.
 Oracle has acquired Sun Microsystems in 2010.
 The impact of this acquisition on MySQL,
OpenSolaris, Java Android lawsuit, OpenOffice,
Grid Engine, etc.
 Oracle has released Java 8 in 2014 (Lambda
expressions, closures, cloud computing, etc.) [10]
