So welcome to the Web 2.0 JavaDoc. The default way of looking up is searching. This is made easier with features like autocomplete.
Java API documentation are displayed in a style that is radically different from the classic javadoc style that ships with the JDK. The documentation includes class source code (where available), ability to leave user notes and ability to transparently navigate between APIs by following code references.
However, the drawback is that it does not have Sunâ€™s JDK documentation, as mentioned in the FAQ.
I hope even gotAPI follows this.
