ABSTRACT
As it is a competitive environment everything is very fast and with the help of internet. In this internet world all
the things are on-line. So, we created the software called On-line Java Compiler. The main aim of this project we
can easily write a java program compile and debug it on-line easily. The client machine does not having java
development kit. The paper aims to describe an online compiler which helps to reduce the problems of portability
and storage space by making use of concept of cloud computing. The ability to use different compilers allows the
programmer to pick up the faster or the most convenient tool to compile the code and remove the errors.
Moreover, a web-based application can be used remotely through any network connection and it is platform
independent. The error/output of the code is store in most convenient way. Also, the trouble of installing the
compiler on each computer is avoided.
KEYWORDS
compiler, online computing, computing.
INTRODUCTION
The main enabling technology for cloud computing is virtualization. Virtualization software
allows a physical computing device to be electronically separated into one or more “virtual”
devices, each of which can be easily used and managed to perform computing tasks.

A. CHARACTERISTICS
● It is elastic, meaning a user can have as much or as little of a service as they want at any
given time.
● The service is fully managed by the provider. The consumer needs nothing but a personal
computer and Internet access.
● Agility: ability to re-provision technological infrastructure resources
● Application Programming Interface (API): accessibity to software that enables machines to
interact with cloud software.
● Cost
● Device and Location Independence: enable users to access systems using a web browser
regardless of their location
● Maintenance
● Multitenancy: enables sharing of resources and cost across a large pool of users.
● Security: can improve due to centralization of data.
B. SERVICES OF CLOUD COMPUTING
1) Software as a service (SaaS): Cloud based application-or software as a service (SaaS)-run on
distant computers “in the cloud “that are owned and operated by other and that connected to user
‘computers via the internet and, usually, a web browser.
2) Platform as a service (PaaS): Platform as a service provides a cloud-based environment with
everything required to support the complete life cycle of building and delivering web-based
(cloud) application-without the cost and complexity of buying and managing the underlying
hardware, software, provisioning and hosting.
3) Infrastructure as a service (IaaS): Infrastructure as a service provides companies with
computing resources including servers, networking, storage, and data centre space on a pay-peruse basis.
II. SYSTEM DESIGN
Technology is applied to generate online java compiler using cloud computing using three tier
structure.
A. DATA LAYER (Backend):
Available in the web server which contains account information about the user.
B. Business Layer (Middle end):
Decision making layer from the application layer.
C. Application layer (Frontend):
User interface, showing data to the user getting input from the user.
D. Compile Option:
This would take the code into textbox to the server side for its compilation and at the server
side the compiler package has been imported.

E. Execute Option:
The user is provided within links of all executables files that we represent in his/her folder
and were already compiled at least once without errors.
III. ADVANTAGES OF ONLINE JAVA COMPILER
1. They are self-contained units ready to be executed.
2. They are already compiled into machine language binaries.
3. There is no second application or package that the user has to keep up-to-date.
4. If a program compiled for windows on an x86 architecture, the end user only needs a
windows operating system.
5. A pre-compiled package can run faster than an interpreter compiling source code in a real
time.
IV. DISADVANTAGES OF ONLINE JAVA COMPILER
1. A compiler translates the source code into specific machine language.
2. Programs have to specifically compiled for OS x, Windows and Linux, as well as
specifically for 32-bit or 64-bit architectures.
3. Problems for maintaining multiple versions of the source code for the same application.
4. More time spent on source code maintenance, extra trouble when updates are released.
V. IMPLEMENTATION
The online java compiler provides a feature that enables the output of source code in
multiprogramming languages at run time, based on a single model that represent the code to
render. We can generate assemblies dynamically at runtime and execute. It was assume that
the user will use his/her favorite text editor to create and correct programfiles. This
assumption allowed to create very simple front end that loads quickly and is platform
independent. Although the frontend is designed to be as simple as possible with only a few
commonly used options, it is sufficiently functional and can be used quickly.Check whether
the the text area is empty or not.If it is empty , display the warning message. Otherwise, use
CompileResultClass to represent the of compilation, that are returned from the compiler,
CompilerErrorClass to represent a compiler error or warning and CompilerParameterClass to
represent the parameters to invoke the compiler. After successful compilation compiler
generate either .classfile. The .classfile produce the desired output for the given source code.

As compared to the current scenario where each machine need to install the compiler
separately. This would eliminate the need to install the compiler separately. So, we can check
the code at the centralized server. Another advantage of this project is that whenever the
compiler package is upgraded it can be done easily without again installing it on each and
every machine.
