It equals true. It equals false. It equals 0. It equals 1. It equals -1. Which boolean expression about p1 and p3 is true? p_1 == p3 p1.equals(p3) p1.compareTo(p3) = 0 I only II only III only II and III only I, II, and III

Solution

   Position p1=new Position(2,3);
   Position p2=new Position(4,1);
   Position p3=new Position(2,3);
   System.out.println(p1.compareTo(p2));
Answer :-1
      
      
Position p1=new Position(2,3);
   Position p2=new Position(4,1);
   Position p3=new Position(2,3);
   System.out.println(p1.compareTo(p3)==0);
Answer : p1.compareTo(p3)==0 is true
