Java is a widely-used object-oriented programming language created to be secure, fast, and reliable, suitable for a variety of applications from mobile to scientific computing. Its platform, consisting of a compiler, execution engine, and libraries, supports the development and execution of Java applications. Key features of Java include its simplicity, robustness, platform independence, and support for object-oriented programming concepts such as abstraction, encapsulation, inheritance, and polymorphism.

2. What is Java?
UNDERSTANDING DATA SCIENCE
Java is a popular object-oriented, general-
purpose, and class-based programming
language. It has been created to have fewer
implementation dependencies.
Developers around the world consider java as
secure, fast, and a very reliable programming
language. It is being used for developing
simple to complex java applications used in
mobiles, computers, data centres, scientific
computers, ATM machines, etc.
JAVA PLATFORM
The Java Platform is the amalgamation
of programs that assists the
programmers to create and execute
Java applications effectively. This
platform consists of a compiler,
execution engine, and libraries.
In simple words, we can say that the
Java Platform is a combination of
computer software and applications.
 Sun Microsystems Inc., released JAVA in 1991.
 James Gosling and Patrick Naughton are the brains behind Java
 Java makes it possible to develop modular programs and reusable code

3. An Object Oriented Language
JAVA is an Object Oriented Language!
The programs in Java are organized as a
collection of objects. Each of them has
to represent an instance of a class.

9. www.lset.uk
Exploring Each Concept of OOP
Abstraction
It is the extraction of
important
characteristics of an
object that
differentiates from
other objects.
Encapsulation
It is the process of
hiding the
implementation
information of a
class. It is also
forcing the user to
utilize an interface to
use the data.
Inheritance
It is the process in
which a class gains
the properties and
features of the other
class.
Polymorphism
It is the ability of
various methods
to exist in
numerous
different forms.

Java is a Simple
Language
It does not consist of
advanced and complicated
features like other
programming languages.

Java only faces two major problems that cause failure
 Memory Management Mistakes
 Mishandled Runtimes

Development
Kit (JDK)
It is a software
development
environment used for
developing java
applications and
applets.
Java Virtual
Machine (JVM)
It is an engine that
facilitates the runtime
environment to
execute Java code or
applications efficiently.
Java Runtime
Environment
(JRE)
It is a specialized
software developed to
run other software. It
helps you to run a
Java program with
ease.
