Welcome
to this blog. We will be posting a series of blogs as a part of our Home
assignment on the topic “OOP Concepts in Java”.
Java is an Object Oriented Programming language.
A program is basically a set of instructions that a
computer follows in order to execute a particular task. The two approaches for
high-level programming are Object Oriented Programming and Procedure Oriented
Programming. A program can be written in both the
languages, but if the task is highly complex, OOP is preferred over POP.
In POP the same data is updated as it
moves through the code. This is a potential risk for ‘data security’ as well as
‘code reusability’. This makes the code lengthy and hard to understand with
increased bugs.Object Oriented Programming helps us overcome these flaws. With various features like Abstraction, Encapsulation,
Inheritance and Polymorphism (to be discussed later in this series) an OOP
approach helps us overcome the flaws in POP approach.
Features of Java
Java is a simple language and any
programmer familiar with C or C++ can become proficient in it. Also there are
no structures, unions, pointers, pointer arithmetic or operator overloading in Java
making it easy to understand.
Java is a platform independent language.
The Java source code is converted to byte code by the compiler
which can be executed on any platform on with the JVM(Java Virtual Machine).
Java has excellent API Support that
includes many Java classes, packages and libraries.
Java applications are used in
various sectors such as education, e-commerce, gaming, multimedia, embedded
systems etc.
‘Android Studio’ which is a popular
mobile application development platform uses Java.
Along with the ARM (32 bit) and
THUMB (16 bit) instruction modes, the ARM processor also supports the Jazelle DBX (direct bytecode execution) an extension that
executes Java bytecode in hardware.
The most important reason to learn Java
is that it is the most popular language in the industry. Java developers are in
high demand and are also well paid for their skills.
In the upcoming blogs we will further
dive into the basic concepts and implementation of OOPs using Java.
