What is this Output !

	int xPosition;
	int yPosition;
	PointForPassReferenceTypeParametersByValue(int x, int y){
		xPosition=x;
		yPosition=y;
	}


}

OUTPUT: -

The reference variable p which is initially pointing to a Point.. object located at (2,3), inside the method moveP() refers to another newly created object of the same Point.. type located at (10,20).
The proof is taking the X and Y position of the Point.. object pointed by the reference variable returned by moveP(); i.e. X:passbyvaluepracticetest.PointForPassReferenceTyp eParametersByValue@2f78743band Y:passbyvaluepracticetest.PointForPassReferenceTyp eParametersByValue@d16e5d6.




But due to pass by value, outside moveP(), p still refers to the same object. Proof is X: 2 and Y: 3.

WHAT IS THIS? X:passbyvaluepracticetest.PointForPassReferenceTyp eParametersByValue@2f78743band Y:passbyvaluepracticetest.PointForPassReferenceTyp eParametersByValue@d16e5d6.
