ACKNOWLEDGEMENT
One of the most pleasant aspects of writing an acknowledgement is the opportunity to thank
all those who have contributed on it. Unfortunately, the life of expression of gratitude – no
matter how extensive – is always incomplete and inadequate. This acknowledgement is no
exception.
I would like to thank…………………………………………, who gave me great opportunities to learn and
experience in this corporate world. Also provided me all the guidance and support in realizing
the dissertation.
I am especially indebted to Mr…… … … … … … , my Training In charge at … … … … … … who
gave me an opportunity to get exposed to the wonderful world of Programming
through Core Java(J2SE) and Some Part of Advanced Java especially my topic “JAVA

Introduction to JAVA: Java is a programming language originally developed by James Gosling at Sun
Microsystems (which is now a subsidiary of Oracle Corporation) 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. Java is a general-purpose, concurrent, class-based,
object-oriented language that is specifically designed to have as few implementation
dependencies as possible. It is intended to let application developers "write once, run
anywhere". Java is currently one of the most popular programming languages in use, and is
widely used from application software to web applications.
Principles







There were five primary goals in the creation of the Java language
It should be "simple, object-oriented and familiar".
It should be "robust and secure".
It should be "architecture-neutral and portable".
It should execute with "high performance".
It should be "interpreted, threaded, and dynamic".
Java is a fully Object Oriented language because object is at the outer most level of data
structure in Java. No stand alone methods, constants, and
Variables are there in Java. Everything in Java is object even the primitive data types can
also be converted into object by using the wrapper class.
Java Technology
As a development environment, Java technology provides you with large suits of tools:
 A compiler (javac)
 A interpreter(java)
7
Object and Methods
Java is an object-oriented programming language, abbreviated OOP.
Oops is a programming methodology that views a program as similarly consisting of objects that
interacts with each other by means of action.
Object oriented programming has its own specialized terminology. The objects are called,
appropriately enough, objects. The actions that an object can take are called methods.
A java application program is a class with a method named main, and when you run the java
program the run-time system automatically invokes the method named main.
There are two kinds of java programs
 Applets (Program that run from a web browser).
 Applications (Program that run on computer like other programs).
FEATURES OF JAVA:Platform Independent
The concept of Write-once-run-anywhere (known as the Platform independent) is one of the
important key feature of java language that makes java as the most powerful language. Not
even a single language is idle to this feature but java is closer to this feature. The programs
written on one platform can run on any platform provided the platform must have the JVM.
Simple
There are various features that make the java as a simple language. Programs are easy to write
and debug because java does not use the pointers explicitly. It is much harder to write the java
programs that can crash the system but we cannot say about the other programming languages.
Java provides the bug free system due to the strong memory management. It also has the
automatic memory allocation and deallocation system.
Object Oriented
To be an Object Oriented language, any language must follow at least the four characteristics.
Inheritance : It is the process of creating the new classes and using the behavior of the existing
classes by extending them just to reuse the existing code and adding the additional features as
needed.
Encapsulation: It is the mechanism of combining the information and providing the abstraction.
8
Polymorphism : As the name suggest one name multiple form, Polymorphism is the way of
providing the different functionality by the functions having the same name based on the
signatures of the methods.
Dynamic binding : Sometimes we don't have the knowledge of objects about their specific
types while writing our code. It is the way of providing the maximum functionality to a program
about the specific type at runtime.
As the languages like Objective C, C++ fulfills the above four characteristics yet they are not fully
object oriented languages because they are structured as well as object oriented languages. But
in case of java, it is a fully Object Oriented language because object is at the outer most level of
data structure in java. No stand alone methods, constants, and variables are there in java.
Everything in java is object even the primitive data types can also be converted into object by
using the wrapper class.
Robust
Java has the strong memory allocation and automatic garbage collection mechanism. It provides
the powerful exception handling and type checking mechanism as compare to other
programming languages. Compiler checks the program whether there any error and interpreter
checks any run time error and makes the system secure from crash. All of the above features
make the java language robust.
Distributed
The widely used protocols like HTTP and FTP are developed in java. Internet programmers can
call functions on these protocols and can get access the files from any remote machine on the
internet rather than writing codes on their local system.
Portable
The feature Write-once-run-anywhere makes the java language portable provided that the
system must have interpreter for the JVM. Java also has the standard data size irrespective of
operating system or the processor. These features make the java as a portable language.
Dynamic
While executing the java program the user can get the required files dynamically from a local
drive or from a computer thousands of miles away from the user just by connecting with the
Internet.
9
Multithreaded
As we all know several features of Java like Secure, Robust, Portable, dynamic etc; you will be
more delighted to know another feature of Java which is Multithreaded. Java is also a
multithreaded programming language. Multithreading means a single program having different
threads executing independently at the same time. Multiple threads execute instructions
according to the program code in a process or a program. Multithreading works the similar way
as multiple processes run on one computer.
Compiler/Interpreter Combo
Code is compiled to byte codes that are interpreted by a Java virtual machines (JVM) .This
provides portability to any machine for which a virtual machine has been written. The two steps
of compilation and interpretation allow for extensive code checking and improved security.
Several dangerous features of C& C++ eliminated
 No memory pointers
 No preprocessor
 Array index limit checking
Security
No memory pointers
Programs run inside the virtual machine sandbox.
Array index limit checking
Code pathologies reduced by
 byte code verifier - checks classes after loading
 Class loader - confines objects to unique namespaces. Prevents loading a hacked
"java.lang.SecurityManager" class, for example.
 Security manager - determines what resources a class can access such as reading and
writing to the local disk.
Good Performance
Interpretation of byte codes slowed performance in early versions, but advanced virtual
machines with adaptive and just-in-time compilation and other techniques now typically
provide performance up to 50% to 100% the speed of C++ programs.
Built-in Networking
Java was designed with networking in mind and comes with many classes to develop
sophisticated Internet communications. Features such as eliminating memory pointers and by
checking array limits greatly help to remove program bugs.
