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?
Introduction
Java programming is a simple language and utilize OOPs concept features in programming
as developing classes and importing methods and it is similar to C++ object oriented
concepts. Java language is characterized by a determination and comprises a developing
paradigm, interpreter, library files and a runtime environment such as Java virtual machine
(JVM). This JVM runtime enables software engineers to compose source code in a different
language than the java which still keeps running on the JVM. The Java stage is generally
connected with the JVM and libraries of java file (Shaykhian & G.A., 2007).
Principles
The java has 3 most used principles are an inheritance, polymorphism, and encapsulation and
it follows OOPs programming concepts which have classes and objects methodology. An
object is main element which consist of attributes and methods. The class is part of program ,
outline based on which objects are developed (Malabarba, Pandey, R., Gragg, Barr, E, J, 2000).
Inheritance:
This principle is used for parent and child properties or attributes inheriting. Basically child or
derived class can inherit the properties of the base class.
Polymorphism:
'Poly' implies numerous and 'transform' implies forms. This implies that it has articulations that have
numerous structures or similar proclamations can have diverse implications in various settings.
Encapsulation:
It means that binding of attributes and its properties is called data encapsulation.
Features
Java has a special addition for reusability of Code.
Accentuation on information as opposed to the method.
Information is covered up and can't be used by outer functions.
Objects can work with each other through functions or methods
New data information and methods can be effortlessly included.

Java has many more features to use in programmings such as robustness, more secure of
data, multithreading, applets implementation for web framework or more.
Characteristics
Java has many characteristics similar to features in a different manner as follows:
Distributed:
Java was composed of the conveyed condition.
Java can be transmitted, run over the web.
Interpreted:
Java supports cross-stage code using Java byte code.
JVM can change Bytecode in any phase.
Object-oriented:
Object-oriented programming concepts are used in Java dialect.
Similar to C++, java gives the greater part of the OOP highlights.
Java is unadulterated Object oriented language and C++ is not fully based on OOP.

1.2 Critically evaluate the environmental flexibility of programming in Java and thus in this context
explain the role of Java Virtual Machine (JVM).
Platform Independence
Java dialect is organize free. As an issue of first significance, its source code gets collected into a class
record which is generally called Byte Code. Byte code contains machine headings for the working
system. This made byte code is same for all phases of OS like Windows, Linux, Mac et cetera. Byte
code is evaluated and deciphered by Java Virtual Machine (JVM). JVM is organize subordinate yet it
is open for all stages. In this way byte code headings and JVM together influences Java to organize
self-ruling.
Embedded Hardware Programming
Java gives an extension of Micro Edition API which is sensible for embedded applications and known
as Java ME Embedded. It engages human to become significantly secure, strong, versatile and
pragmatic applications for embedded contraptions like flight control structures and machines
identified with cash exchange and that's only the tip of the ice berg.
Mobile Applications
Java Mobile Environment stays for Java Micro Edition. It enables us to make applications for
contraptions like set-top boxes, PDAs et cetera. Java ME is especially expected for battery worked
devices with some memory and dealing with speed.

M1:
Role of JVM
JVM remains for java virtual machine which is dynamic or virtual figuring machine is the usage of
java virtual machine specification. It deciphers the interpreted java programmed code as the
bytecode and aides in execution of program relying on the particular stage. Java is platform
independent language i.e. it can keep running on any stage without reworking the code. This
component is supported by JVM. Fundamentally JVM is set of PC programs and data structures that
run arranged bytecode on any machine such as Java language which is once it is compiled can run
anywhere. JVM is virtual, on the grounds that nature in which it runs bytecode is to such an extent
that it stays isolated from the OS and can be expelled or introduced without influencing it. JVM
changes over the bytecode into the machine or a platform based code and after that run it.
