Features of the Java Programming Language

Java Features or Characteristics or Buzzword

* Simple:

The Java language is easy to learn. Java code is easy to read and write.

* Familiar:

Java is similar to C/C++ but it removes the drawbacks and complexities of C/C++ like pointers and multiple inheritances. So if you have background in C/C++, you will find Java familiar and easy to learn.

* Object-Oriented:

Unlike C++ which is semi object-oriented, Java is a fully object-oriented programming language. It has all OOP features such as abstraction, encapsulation, inheritance and polymorphism.

* Robust:

With automatic garbage collection and simple memory management model (no pointers like C/C++), plus language features like generics, try-with-resources,… Java guides programmer toward reliable programming habits for creating highly reliable applications.

* Secure:

The Java platform is designed with security features built into the language and runtime system such as static type-checking at compile time and runtime checking (security manager), which let you creating applications that can’t be invaded from outside. You never hear about viruses attacking Java applications.

* High Performance:

Java code is compiled into bytecode which is highly optimized by the Java compiler, so that the Java virtual machine (JVM) can execute Java applications at full speed. In addition, compute-intensive code can be re-written in native code and interfaced with Java platform via Java Native Interface (JNI) thus improve the performance.

* Multithreaded:

The Java platform is designed with multithreading capabilities built into the language. That means you can build applications with many concurrent threads of activity, resulting in highly interactive and responsive applications.

* Platform Independence:

Java code is compiled into intermediate format (bytecode), which can be executed on any systems for which Java virtual machine is ported. That means you can write a Java program once and run it on Windows, Mac, Linux or Solaris without re-compiling. Thus the slogan “Write once, run anywhere” of Java.

પટેલ સમાજનો ઈતિહાસ જાણો : કોણ અને ક્યાંથી આવ્યા હતા પાટીદારો

PATIDAR The  Patidar  are a  caste  found in the state of  Gujarat , India. They were formally recognized as a separate identity in the 1931 census of India, having previously been classified as  Kanbi . They are among the most studied of Indian castes and the process leading to their recognition is a paradigmatic example of the  invention of tradition  by social groups in India. પટેલ અથવા પાટીદાર અથવા કણબી એ ભારત દેશનાં પશ્ચિમ ભાગમાં આવેલા ગુજરાત રાજ્યની એક મુખ્ય જ્ઞાતિ છે. પટેલોમાં લેઉવા પટેલ અને કડવા પટેલ એમ બે પેટા જ્ઞાતિ છે. ઇતિહાસ તેઓ કુર્મઋષિનાં વંશજો હોવાનુ મનાય છે તેથી તેઓ શરૂઆતમાં કુર્મી તરીકે જ ઓળખાતા હતાં. ઇતિહાસકારોનાં મત અનુસાર પટેલો મધ્ય એશિયા માં આસુ નદી પાસે પામીર નામનાં ઉચ્ચ પ્રદેશમાં વસતા હતાં. ત્યાંથી એક સમુહે અફઘાનિસ્તાન માં થઈને હિન્દુકુશ પર્વતમાળા ઓળંગી ખૈબરઘાટનાં માર્ગે પંજાબ માં દાખલ થઈને વસવાટ કર્યો હતો તેમ કહેવાય છે. ભારત દેશમાં પંજાબના સપ્તસિંઘુ પ્રદેશ ‘લેયા’ પ્રદેશમાંથી આવેલા કૂર્મિ ક્ષત્રિયો લેઉઆ કહેવાય...

Java Event Delegation Model, Listener and Adapter Classes

Image
Java Event Delegation Model The Delegation Event model is one of the many techniques used to handle events in GUI (Graphical User Interface) programming languages. GUI represents a system where an user visually/graphically interacts with the system. Other interactive systems are text based or called CUI (Character User Interface). CUI interacts with the system by typing out commands in the console. GUI programming is inherently event driven; that means, whenever an user initiates an activity such as a mouse move that changes the co-ordinates of the mouse pointer in the screen, or clicks a button, scrolls a page, and so forth, each is deemed as an event that the GUI event handler maps the activity to a piece of code that explains what response the application should provide to the user. Any program that uses GUI (graphical user interface) such as Java application written for windows, is event driven. Event describes the change in state of any object.  For Example:  Pre...
