In this post, we will understand abstraction and encapsulation in detail, and discuss a few differences between the both. 1. Encapsulation in Simple Words In simple terms, wrapping the data (state) and the methods (behavior) inside a class in combination with information and implementation hiding...
Let’s see one moreexample of abstraction in Java using interfaces. In this example, I am creating various reports which can be run on demand at any time during the application’s lifetime. As a consumer of the report, a class needs not to know the internals of the report’s run(), ...
Data abstraction is a method where essential elements are displayed to the user and trivial elements are kept hidden. In Java, abstraction is achieved by usingthe abstract keyword for classes and interfaces. In abstract classes, we can have abstract methods as well as concrete methods. What is ...
But when I saw the abstraction article on myjavatrainer.com, It became clear to me that Abstraction and Encapsulation are Apples and Oranges, you can't really compare them because both are required. Encapsulation is how the object is created, and abstraction is how the object is viewed in t...

In short, you can now annotate a whole suite, and then run tests with your annotation in exclusion rules. This will eliminate the whole suite with its beforeAll(), afterAll() and any other blocks surrounding method invocations. How to prepare a tag Just create a simple Java annotation like...
This is achieved in Java using access modifiers. A simple example would be defining a private variable and giving access to it using getter and setter methods or making a method private as it's only use is withing the class. There is no need for user to know about these methods and ...
.NET has many built-in cryptographic algorithms, both in fully "managed" code and as wrappers to the CryptoServiceProviders in the MFCs. Java has a few of the same. Unmanaged languages would use the MFCs. They're all well-documented and any competent developer should...
In 1973, Analívia Cordeiro produced the videodance M3x3. Filmed in a Brazilian television studio and choreographed by Cordeiro with a computer, the work explores the limits of the human body through abstraction and its inhabitation of a new media landsc
While I wouldn't necessarily call it _easy_, I'd venture to say that I have had success in switching from MS-SQL to Oracle in a Java appserver environment; all of the database work was done in stored procedures, so the bulk of the porting was done by the dba. Our tasks basically...
