An agile dynamic language for the Java Platform with many features that are inspired by languages like Python, Ruby and Smalltalk, making them available to Java developers using a Java-like syntax. ... [More] Developing web applications , writing shell scripts easily, writing concise, meaningful, test cases using Groovy's JUnit integration, or prototyping and producing real industrial strength applications have never been so concise and groovy. [Less]

Grails aims to bring the "coding by convention" paradigm to Groovy . It's an open-source web application framework that leverages the Groovy language and complements Java Web development. You can ... [More] use Grails as a standalone development environment that hides all configuration details or integrate your Java business logic. Grails aims to make development as simple as possible and hence should appeal to a wide range of developers not just those from the Java community. [Less]

Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and ... [More] functional languages. It is also fully interoperable with Java. [Less]

JRuby is an 100% pure-Java implementation of the Ruby programming language. JRuby is the effort to recreate the Ruby interpreter in Java. JRuby is tightly integrated with Java to allow both to ... [More] script any Java class and to embed the interpreter into any Java application. [Less]

Jython is a Java implementation of the Python programming language. It allows users to compile Python source code to Java byte codes, and run the resulting bytecodes on any Java Virtual Machine. It is ... [More] a very seamless and smooth integration with Java: from Python you have complete access to all Java libraries, can build applets, can integrate with Java beans, and can subclass Java classes in Python and vice versa. Like Python, and unlike Java, Jython can also be used interactively: just type some Jython code at the prompt and see the results immediately. [Less]

ASM is a Java bytecode manipulation framework. It can be used to dynamically generate stub classes or other proxy classes, directly in binary form, or to dynamically modify classes at load time, i.e. ... [More] , just before they are loaded into the Java Virtual Machine. ASM offers similar functionalities as BCEL or SERP, but is much smaller (33KB instead of 350KB for BCEL and 150KB for SERP) and faster than these tools (the overhead of a load time class transformation is of the order of 60% with ASM, 700% or more with BCEL, and 1100% or more with SERP). Indeed ASM was designed to be used in a dynamic way* and was therefore designed and implemented to be as small and as fast as possible. [Less]

Clojure is a dynamic programming language for the JVM. It is interactive, yet compiled, with a robust infrastructure for concurrency (STM). It is a functional dialect of Lisp, with a rich set of ... [More] immutable, persistent data structures and a macro system. [Less]

GNU Classpath (Essential Libraries for Java) is a project to create free core class libraries for use with virtual machines and compilers for the java programming language. It includes all native ... [More] methods and core classes necessary for a completely functional java runtime. [Less]
