Java platform tools and technology

Java tools and technology help application developers build better code faster. Some Java tools are aimed at increasing the efficiency of applications running on the Java platform in terms of the computing and storage resources necessary to run the application. Other Java technologies are focused on making Java applications more maintainable via modularity and component reuse or other strategies. Still other tools and technologies are designed to make each application developer more effective by increasing communication (collaboration tools) or reducing the need for repetitive boilerplate code (high level abstractions and Java code libraries).
