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]

Introduction…

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

Why Java

What Java Can Do? [4],[5]

Java is platform-independent Java is Portable (WORA) Java is Object-Oriented Java is Interpreted Java is Robust Java is Distributed Java is Secure Java is Multithreaded Java is Dynamic

Why Java…

What Java Cannot Do? [6]

• 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.)

How Many Java Programmers in Saudi Market?

Quota of Java in the Marketplace…

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: …

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]
