question: public int compareTo ( Object o ) { if ( o == this ) { return 0 ; } Point p = ( Point ) o ; for ( int i = 0 ; i < getSize ( ) ; i ++ ) { if ( getValue ( i ) != p . getValue ( i ) ) { return ( int ) Math . signum ( p . getValue ( i ) - getValue ( i ) ) ; } } return 0 ; }
target:  True iff the given object is a point with the same coordinates as this one.
