The following dialogs are used in the JDT's default Java editor.
If the import assistant cannot decide which type to import, these dialogs allow you to select a type from a list.
If you select a type or class and select Edit > Open Type Hierarchy from the menu bar, the selected type is opened in the Hierarchy view.
This dialog allows you to search the active editor for an expression and, if you want, to replace matches with another expression of your choice.
