Type Casting in Java

-
While programming, sometimes there is situation encounter, where we have to store a value of one type into a variable of another type. In such situations, we have to cast the value to be stores by processing it. The syntax is:

 type variable 1 = (type) variable2;

The process of converting one data type to another is called casting.

Casting is often necessary when a method returns a type different than the one we require.

Concept of OOPS

-
In this post, I generally explain the concepts of OOPS in simple way, for understanding them. First of all, the concepts of OOPS are- Objects Classes Data Abstraction Data Encapsulation Inheritance Polymorphism Message passing. Now I didn't explain these in a long para, except of long para I use single line so you can easily understand these terms. Objects-  Basic entities of the program. Eg- A single student. Classes-  Collection of similar objects. Eg- A group of students. Data Abstraction-  Representing essential features while hiding the background details. Data Encapsulation-  Wrapping up of data and the functions that operate on the data. Inheritance-  Process by which a class acquires properties of another class. Polymorphism-  ability to take many forms. ( furhter information in polymorphism post). Message passing-  Objects communicate with each by use of function calls.

NetBeans For Java How To Install and Get Started with Java Programming (on Windows)

-
NetBeans (@ http://netbeans.org ) is an open-source Integrated Development Environment (IDE). NetBeans began in 1996 as a Java IDE student project at Charles University in Prague. Sun Microsystems acquired NetBeans in 1999. In 2010, Oracle acquired Sun (and thus NetBeans). Compared with its rival Eclipse ( http://www.elicpse.org ) (both are open-source, so I don't know what are they competing for?), NetBeans provides seamless support for Java AWT/Swing, Java ME mobility pack, Java EE, and bundled with an excellent profiler for performance tuning. How to Install NetBeans 8.2 Step 0: Install JDK To use NetBeans for Java programming, you need to first install Java Development Kit (JDK). See " JDK - How to Install ". Step 1: Download Download "NetBeans IDE" installer from http://netbeans.org/downloads/index.html . There are many "bundles" available. For beginners, choose the 1st entry "Java SE" (e.g., " netbeans-8.2-javase-windows.exe ...
