The most visible immediate change is to the Javadoc generated HTML files. These now support a method summary section where tabs have been added to select between types of methods: static, instance, abstract, concrete, or deprecated. The existence of these tabs depends on the methods in the class or interface. A new DocTree API () has been added. The API extends the Compiler Tree API and allows for better access to Javadoc contents. The Javadoc Access API () provides access to the Javadoc tools from a Java application. In addition, the javadoc tool now checks for invalid HTML code. This check can be turned off using the –Xdoclint option.
