How can we access an interface from another interface and how do you access from a class?
Yes, you can define an interface inside a class and it is known as a nested interface. You can’t access a nested interface directly; you need to access (implement) the nested interface using the inner class or by using the name of the class holding this nested interface.
How do I find all implemented classes for an interface in eclipse?
Open Java Search, enter the interface name, click “Implementors” and you will “find which classes implement a particular interface.”
How is an interface used in a class?
An interface is a completely ” abstract class ” that is used to group related methods with empty bodies: To access the interface methods, the interface must be “implemented” (kinda like inherited) by another class with the implements keyword (instead of extends ). The body of the interface method is provided by the “implement” class:
How to access the interface methods in Java?

Can a implicit interface be turned into an explicit interface?
An implicit interface can easily be turned into an explicit one by collecting all those public methods (except for the constructor, which should not be considered a regular method), stripping the method bodies and copying the remaining method signatures into an interface file.
Is there a way to navigate to real implementation of?
If you use go to implementation of Write in UseIWrite, it takes you to the declaration of the interface, because at that point any of the IWrite implementations could be passed into the method. Thankfully some tools like for example ReSharper offer you to find all usages of the method, so you can easily navigate to the desired implementation.
