optimizes Java bytecodes on behalf of its clients. In this article, we present the design, implementation, and evaluation of a compilation server that compiles and. Since compilation overhead impacts the execution time of the application and induces run-time pauses, we explore offloading compilation onto a compilation server. Modern JVM implementations interleave execution with compilation of “hot” methods to achieve reasonable performance.

Ultimately, the trouble of installing the compiler on each client machine is avoided. Additionally, a web-based system can be used remotely through any network connection and is accessible worldwide. Furthermore, the programmer can test his/her code in different version of compiler for backward compatibility check.

The ability to use different version of java compilers allows the programmer to write code faster and in convenient way hence compiling the code and removing the errors. This paper aims to describe an online compiler which helps to reduce the problems of portability, storage space and dependencies for Java Runtime Environment (JRE) by making use of concept of cloud computing. The client machine does not have to install or configure Java Development Kit. The main aim of this project is to compile and run java code at the server side as the code is given from the client interface. So I created a research project called 'Java Code Engine Online'. To work fast and efficient, plenty of high configured resources like cpu, memory, storage are required. As this is the age of internet, everything digital are online and need to work fast and efficiently. Java is a general-purpose, object-oriented, concurrent, class-based, computer-programming language that runs on Java Virtual Machine (JVM) regardless of computer architecture.
