• Interface3D an interface that ThreeDimension implements
  • public interface
  • abstract methods for getX(), getY(), getZ(), and set3D()
    • set3D() has one argument for a ThreeDimension object
  • default public method distance()
    • returns the primitive double 0.0
    • one argument for a ThreeDimension object
    • prints "Default method - cannot calculate the distance to " where is the ThreeDimension
    • Example output:

Default method - cannot calculate the distance to (3, -3, 5)

//I get everything else but I don't understand how to do the instruction in bold. Are they using the same object or a different one. As for the double 0.0 can I use the return method or is something else more appropriate if it is the right move should I do it after the System.out.print? May you please help me and explain your work
