Introduction
This report is composed of Wooden Flooring service in which they want to calculate the area, cost
and time for particular rooms. This project is developed and designed by utilizing Java programming
in Netbeans which is as an IDE (Integrated Development Environment). The java provides various
methods, libraries to execute the functionalities for calculating wooden flooring. The NetBeans
provide a platform for performing the calculation and give an estimation of costly and also provide a
gateway to make payment through various modes such as by cash, debit card and credit card with the
calculating amount to pay for each mode. This report also provides testing of this system and various
users reviews to enhance the performance of the system and this report also provides a demonstration
for executing the source file and how to use NetBeans for developing the system.

1.1 Java has many features including Object Oriented, Platform Independent, Robust,
Interpreted, and Multi-threaded. Discuss the principles, characteristics, and features of
programming in Java?
Java was given by Sun Microsystems in 1991 which is a very easy programming language. Later on,
it was taken by Oracle Corp., Java provides various features as its compilation debugging and
programming is much easier as its code can be reused and run on any platform without hassle. The
Java programming widely used and it utilizes the concepts of OOPs programming which is very
known. Initialization of Java programming by importing packages or modules which make code
executable by finding libraries method.
It has 4 most common elements which are used in programming to provide functionalities as:
1. Inheritance:
Inheritance is a feature of OOPs which provides accessibility for a child class to base class
methods using access modifiers which help in saving time and not to define again and again
same methods. Basically used for deriving the functions of a base class in derived class as a
hierarchy.
2. Polymorphism:
It is also a part of OOPs and it means many forms as name resembles poly means ”many” and
morphs is for “forms”. Basically, it means that not define the same method again and again,
just override that method which is already defined in some class and utilize in many ways.
3. Data Abstraction:
Data abstraction is used in any programming as it hides unnecessary details of data
information. For example, take a login page in which by entering credentials, it’ll login in that
system but never shows how logged in or their process. So data abstraction basically hides the
unwanted details and shows the required part.
4. Encapsulation:
It is used for hiding the data part which must not be shared with anyone, so it encapsulates the
data and compiles it without showing its working. It can be possible only by using access
identifiers which protect the code from used by externals by keeping safe and send for
manipulation.
There are some characteristics of java as:

Object-oriented:
Java utilizes most of the features of OOPs programming which provides classes and objects
methodologies to make a program and provide security functionalities by using access modifiers.
Security:
Java is much secure as it doesn’t have a pointer which exploits the overflow conditions of buffer or
stacks which mean that data can be accessed by out of boundaries and it makes java secure.
Robust:
Java is more reliable language as it has compiler itself which find the bugs or errors if present in
programming before completion and it helps in to develop functional code error free.
Distributed:
Java has distributed language as it can create a various application which is distributed, for example,
enterprise java beans (EJB) and remote method invocation (RMI) which are utilized for developing
distributed applications which help to connect through the internet, see many times in applets.
Portable:
Java is portable language as it can be compiled on different platforms. Basically, it generates byte
code which can be executed on various platforms.
Multithreading:
It is most used components which provide execution 2 or more programs simultaneously by using
packages which binds different programs in a single code.
Simple:
Java is very simple language as it doesn’t support various features of another language such as
multiple inheritances, overloading of operators, pointers or many more (Corsaro & Schmidt, 2002).
Platform independent:
Java is a platform independent language as it compiler which is javac converts the source code save
with .java extension into byte code saved by .class extension and this byte code can run on any
platform which makes java platform independent.
