Finding implementations of an interface in Eclipse

I'm looking at the following method.

public void setRecordValidator(Validator recordValidator) {
    this.recordValidator = recordValidator;
}

In this case class Validator is an interface. I'm not sure what kind of object to pass on to the method since I'm not sure what classes actually implement Validator.

The question is how can I view classes that implement Validator in Eclipse?

Select Validator in 

 public void setRecordValidator(Validator recordValidator) {
    this.recordValidator = recordValidator;
 }

and press F4 key.

There's a few ways to get this information, here are some of them:

Right click on the name of the interface and select Open Type Hierarchy (the shortcut for this is F4 by default).

Alternatively, you could right click it and choose References > Hierarchy instead.

CTRL+T will give you a Javadoc-style popup with the type hierarchy inside.

There are plenty of other ways to do this, so pick your poison really.

Click on Validator somewhere in the code and press Ctrl+T - this will open the Type Hierarchy popup.
