How to refactor fast in intellij - move instance method

Question

What is the fastest way in Intellij to refactor a java instance method to another class in terms of (refactoring) steps.

For example:

public class Bar {
    public String getX(){
        return "x";
    }
}

public class Foo {
}

public class Runner {
    public static void main(String[] args) {
        new Bar().getX();
    }
}

Refactor to:

public class Bar {
}

public class Foo{
    public String getX(){
        return "x";
    }
}
public class Runner {
    public static void main(String[] args) {
        new Foo().getX();
    }
}

I don't know for sure about intellij, but I can imagine that is not a refactoring which can be done automatically, or at least in a general-enough way to make it useful: what instance of Foo should the getX method be invoked on? — Andy Turner

The instance of Foo doesn't matter. new Foo() is fine or if all the instances of Foo in the program are foo the foo would be fine too. — Maarten

Why not just refactor the name of class Bar to Foo (assuming Foo doesn't not exist) — Bon

Right - it might not matter to you, in this case, but in the general case it would. I can't see a broad-enough use case to warrant making that a built-in refactoring. I'd just get a cup of coffee and start hacking on sed... :( — Andy Turner

If the method really is as trivial as it is here (and I'm guessing it's not), you can make Bar.getX() call the static method Foo.getX(), then inline all of the calls to Bar.getX(). — Andy Turner

You can rename class/method/variable with Shift+F6 (just select name and press hotkeys), but You should aware that it don't remove or change already existed name, so you will get a duplicate. The best option remove Foo class before you rename Bar class.

In IntellJ IDEA 15 you can do:

Position on the method getX();
Press Ctrl/Cmd+F6 (Change Signature)
Add parameter: Type=Foo, name=foo, Default value=new Foo()
Press F6: Move method
Select Foo foo as destination and press Refactor
