How to navigate to implementing class from interface in Eclipse? [duplicate]

Question

Suppose I have:

interface Foo {
  void doStuff();
}

class FooImpl implements Foo {
  public void doStuff() {
    // stuff
  }
 }

When I see myFoo.doStuff() in my code, if my cursor is over doStuff(), pressing F3 will take me to the doStuff() method in the interface Foo. Of course, I often am much more interested in the implementation of this method, not just the signature.

Does Eclipse have an easy way to navigate from a declaration of a method in an interface to the implementation of that method in the implementing class?

In my case, there will not be ambiguity about what the implementing class is.

Answer 1

Highlight the method name, and press either CTRLT or F4. You'll see a type hierarchy, but linked to the method rather than the containing classes. Select the desired implementation class.

Answer 2

Or - if you have enabled Hyperlinking (see the preference page with that name) - you can press Control (or Command on MacOS) and click on the method name. It will then show a menu with "Open Declaration" and "Open Implementation"...

Answer 3

Select the method and press Ctrl+T.

Also clicking the gray up-arrow on the left hand side of the editor close to the line numbers will take you to a method declaration in an interface. If that same arrow is green, it will take you to a method definition in a super class.
