Implementing a method from Interface Java

Question

Guys could you help explain me the last 2 lines please

MenBook mbobject = (MenBook) other

does it mean that mbobject is an object of the class Menbook? and what does the Other mean?

 public boolean moreExpensiveThan(Object other) {
 If(other == null)
 return false;
 else if (getClass() != other.getClass()) 
 return false;
 else { MenBook mbobject = (MenBook) other;
 return (sellingPrice() >= mbobject.sellingPrice());
 }

Please note that OrderedByPrice is an interface

Answer 1

You are assigning to variable mobject (of type MenBook) the object other (of type Object), after checking that its type is of the correct one (getClass() != other.getClass()).

Answer 2

You are creating a new MenBook object called mbObject and you assign the object called other to it.

The (MenBook) in front of other means you are casting the object called other to a MenBook object.
