Here is a quick tip about how to view the specified Java class hierarchy in Eclipse IDE. As usual, if you want to view the sub type or super type hierarchy structure of a specified class, you will visit the API documentation online,

For example,
WebMarkupContainerWithAssociatedMarkup is a Wicket class. API documentation online -http://wicket.apache.org/docs/1.4/org/apache/wicket/markup/html/WebMarkupContainerWithAssociatedMarkup.html

Steps to view the class hierarchy

Actually, Eclipse IDE does provides a shortcut (CTRL + T) to view the Java class hierarchy, there is no necessary to search the API online.

1. Mouse over the class e.g WebMarkupContainerWithAssociatedMarkup, and point on it.

2. Press on (CTRL + T) combination keys to view the subtype hierarchy .

3. Press on (CTR+T) combination keys again to view the super type hierarchy.
