SPC’s Java training in jaipur programs are so designed to help a student with little or no knowledge of any programming language get comfortable and be able to develop cool applications using this powerful programming language.
Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems’ Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to byte code (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture. This programming language is a general-purpose concurrent class based object oriented programming language, specifically designed to have as few implementation dependencies as possible. It is intended to let application developers “write once, run anywhere”.

What is Abstraction
Abstraction in Java, which is one of the OOPs concepts, is the process of showing only the required information to the user by hiding other details. For example, consider a mobile phone, we just know that pressing on the call button, will dial the required number. But we actually don't know the actual implementation of how a call works. This is because the internal mechanism is not visible to us. This is a real example of abstraction. Similarly, abstraction works in the same way in Object-oriented programming. In this tutorial, we will learn how to achieve abstraction using Java abstract classes and methods.
Ways to achieve Java Abstraction
We can achieve abstraction in java by below 2 ways.
You can refer to Interface in Java tutorial to understand more about achieving abstraction using an interface.
Use of Abstraction
- Provides security by hiding implementation details.
- Provides flexibility for the subclass to implement the functionality of the inherited abstract method of the superclass.
Let's discuss in detail about Java abstract class and methods.
Abstract class in Java
When we declare a class with an abstract keyword, we call it an abstract class. abstract is a non-access modifier keyword that we can use along with a class and method. An abstract class is a special class that is a superclass that contains unimplemented methods. Hence the subclass that inherits the parent abstract class should implement all the abstract methods.
The Java sparrow (Lonchura oryzivora), also known as Java finch, Java rice sparrow or Java rice bird, is a small passerine bird.[2] This estrildid finch is a resident breeding bird in Java, Bali and Bawean in Indonesia. It is a popular cage bird, and has been introduced in a large number of other countries. Some taxonomists place this and the Timor sparrow in their own genus Padda. The Java sparrow is about 15 to 17 cm (5.9 to 6.7 in) in length from the beak to its tip of tail feathers. Although only about the size of a house sparrow, it may be the largest species in the estrildid family. The adult is unmistakable, with its grey upperparts and breast, pink belly, white-cheeked black head, red eye-ring, pink feet and thick red bill.
Both sexes are similar. Immature birds have brown upperparts and pale brown underparts, and a plain head. Very young birds have a black beak with a pink base.
The call is a chip, and the song is a rapid series of call notes chipchipchipchipchipchip.
Molecular phylogeny indicates that this species may have originated in India and dispersed to Africa and Pacific Ocean habitats from there.
6th JUNE, LONDON – The London Java Community meet for a technical session by Ian Ashworth. Showing how development testing and static analysis will help developers find critical defects in code development and accelerate the time to market.

The Java leg of our trip. Started from Jakarta to Yogyakarta by train, to Mt. Bromo and from there to Surabaya
These are fairly large scale, standing about 15 inches tall. I had the stones carved to match my large glass hurricanes.
