intelij idea shortcut to implement interface as a new class

Question

suppose i have a interface like this:

public interface Dumb{
String getDumbName();
}

Is there any shortcut or menu in intellij-idea to create new classes implementing the interface with dummy implement methods like this:

 public class Dumber{
   public String getDumbName(){
return null;
}
    }

Answer 1

There are multiple ways to go about this.

On the interface name itself, you can hit Alt+Enter (Option+Enter on Mac), then pick 'Implement interface'. IDEA will prompt for a class name and a package to put the new class in, then generate an implementation class.

Alternatively, create the class, then add implements Dumb after the name (im<tab> Dumb). IDEA will complain that your class doesn't implement the correct methods, and offer (Alt+Enter Enter Enter) to generate them for you. Hitting Ctrl+I or clicking 'Implement methods' in the Code menu also works.
