How to view all implementors of a given interface in NetBeans for Java?

Question

I'm trying to evaluate NetBeans, being a veteran Eclipse user. In Eclipse I could press F4, and I would a class hierarchy for a given class or Interface. For example - show me all the classes that implements InputStream. It's also important it will show me this across all my dependencies and not just my code.

Answer 1

Try this, select the type e.g. "String", then click with the right mouse button -> Navigate -> Inspect Hierarchy. On the right side you will see a window called "Hierarchy" or maybe just a vertical text with "Hierarchy" which is a minimized window (click to open).

If opened you see a combobox with "Supertypes". Change this to subtypes, there you see all classes or interfaces implementing/extending your interfaces or extending your classes.

Answer 2

Try this,

ctrl + alt + click

this will list all implementations of same interface
