However, you can avoid this by following the below approach: Declare the missing methods abstract in your class. This forces you to declare your class abstract and, as a result, forces you to subclass the class (and implement the missing methods) before you can create any objects.
When you call a method on a variable declared as an interface, Java will look up which method to call in the instance's vtable, which is set when you create the instance based on the class. Thus, it actually calls the implementation definde by the class that that object is an instance of at runtime.
Choose Navigate | Go To Implementation in the main menu, press Ctrl+F12 , or click the symbol while holding Ctrl+Alt keys. Note that in Visual Studio 2017 and later, the Ctrl+Alt -click is used for adding multiple carets.
Yes, we can implement interface methods without using implements keyword.
I do the following:
1) Right click on the method and click "View call hierarchy" (or shortcut Ctrl+K, Ctrl+T)
2) Expand the "Implements x" folder which will then show you all the implementations of that method. Click on one to go there.
Relatively quick and easy. Annoyingly though there doesn't seem to be an equivalent for the interface itself.
update: as of Visual Studio 2015 update 1, right click on a method and select go to implementation. You can also map it to keyboard shortcut via Tools > Options > Environment > Keyboard and search for Edit.GoToImplementation command. The default shortcut is Ctrl+F12. (F12 will navigate to the interface).
With VS2013 one can place cursor over the method, and use Navigate To... (CTRL+,), and it will display all locations where the name is declared. Doesn't work well if different interfaces uses the same method names.
With VS2015 Update 1 there is now a new shortcut called "Go To Implementation".
I created a free extension for Visual Studio 2010 and Visual Studio 2012 called Inheritance Margin to provide this specific feature, as well as give a clear indication when a method implements an interface method due to a signature match. In the current version, you can right click on any glyph to get a menu of items to navigate to.

Right-click then "Find All References".
This will display the line of code for all the places where the method is used including the interface declaration and implementations of the interface method. You can then click on the line to jump to the code location.
Depending on the version of Visual Studio that you have, I'll say conditionally "yes."
I'm currently operating on Ultimate, and don't have other versions to verify this. That said, within Ultimate, you can use the Architecture Explorer to find implementations. It's a little more involved than the right click method, but here's how it works.
View->Architecture Explorer (or CTRL-W, N)Types. Click thisInterfaces
Members will then appear to the right. Click that buttonImplemented by (under Inbound Navigation) and that will provide a list of implementations of your interface.Visual Studio 2015 Update 1 (released December 2015) has now added a right click 'Go To Implementation' feature as standard.
