Juliet saves time: it allows you to quickly grasp which packages and types exist on your classpath, understand how they can be (re)used and lookup details while coding. As a Java programmer you are more or less lost in the complex universe of packages and types found along your classpath, and you have questions: - before you can start to use and reuse types (overview): Which packages are there, which types are in each package, how do they relate to each other, and what exactly do they do? - while you code (details): Which are the supertypes of this type, which are its abstract methods (declared and inherited), how do I call this method, and what does it do? Juliet provides the answers.
