Given:
public interface TestInterface {
default public void samplingProbeProcedure() {
probeProcedure();
System.out.println("Collect Sample");
System.out.println("Leave Asteroid");
}
default void explosionProbeProcedure() {
probeProcedure();
System.out.println("Explode");
}
}

Examine these requirements:

Eliminate code duplication.
Keep constant the number of methods other classes may implement from this interface.
Which method will fulfill these additional requirements?
