167 JGroovy — An Experimental of Extensible Java Compiler

There are many programming languages what designed to express computations that can be performed by a machine. Many programming languages have specific features and some form of written specification of their syntax and semantics. Although some languages extended Java programming language and use advantages from Java Virtual Machine (JVM) those extended languages have their syntax and semantics that make extended languages cannot support all Java features. This paper we introduce the programming language and compiler that support more than one programming languages called 1œJGroovy1 .The JGroovy use Java for a host language and Groovy for a second language. This research is aim to improve a compiler for support more than one programming languages and manage source code before and after compilation with identical standard. The result of experiment the JGroovy compiler support source code better than javac. And support all extension features in Groovy.
