How do you use the @Override annotation?

Use this annotation to tell the compiler that the method is supposed to be overriding a method in the superclass. If by chance it doesn't, the compiler tells you. This allows you to catch typos like wrong case or incorrect return types/parameters.

public class Over {
  public void overrideMe() {
  }
}
class SubOver extends Over {
  @Override
  public void overrideme() {
  }
}
