java Point type subtraction -

i'm trying implement subtraction method

problem when try use it give me error here's code

public point subtract( point p1, point p2) {     point p3 = new point();     p3 = p1 - p2;   ////getting error here     return p3; }   public int ishorizonatalcollision(objects object) {     int tru = 0;     int leftcolli = 1;      point eqp;      eqp =  subtract(posi(), nposi());          if (eqp == objposi(object) )         {             return leftcolli;         }         return tru;      } 

public static point subtract(point p1, point p2) {     return new point(p1.x - p2.x, p1.y - p2.y); } 

or

public static point subtract(point p1, point p2) {     return new point(p1.getx() - p2.getx(), p1.gety() - p2.gety()); }
