For the next two questions, use the following class definitions. public class Machine private double x; public Machine (double x){ this.x = x; } public void noveRight() ws { > public double distFronOrigin() return x; 2 } public class Robot extends Machine private double y; . } In class Robot, if you want distFromrigin() to return V x2 x2 + y2, and keep moveRight() unchanged (ie. it will remain the same in Robot) , what is the best you should do? Override both distFronrigin() and moveRight() without referencing super. distFronOrigin() or super.noveRight() Only override distFromrigin() to return Math.sqrt(x*x + y*y). Only override distFromrigin() while referencing super.distFromOrigin() Override distFromOrigin() to return super distFromOrigin() and override noveRight() to call super moveRight()
