Question

Is there any way by which I can find out all classes which implement a particular interface?
For example, if I have a interface as follows:

public interface myIntFac{}

I want to find all classes inside current project that implement this interface. How can I find it out in Eclipse?

Answer 1

At the interface level, you can use (assuming the cursor in on the interface)

• CTRL+T to show the Quick Type Hierarchy
• F4 to Open Type Hierarchy

At the method level, if you hover a method while holding down the control key, a pop-up box gives you the following choices:

• Open Declaration
• Open Implementation

_{(source: eclipse.org)}

And from anywhere, you can use:

• CTRL+SHIFT+H to open the Open Type Hierarchy pop-up and search for any type/interface.
