Public class mysquare extends griditem { private int side; public mysquare(int xvalue, int yvalue, int s) { x = xvalue; y = yvalue; side = s; } public double getarea() { return side * side; } public boolean containspoint(int xvalue, int yvalue) { return xvalue > = x & & xvalue < = x + side & & yvalue > = y & & yvalue < = y + side; } } required put a system. out. println statement into each containspoint method (griditem, mycircle, and myrectangle). run the program and examine the output. you will notice that griditem’s containspoint method is never called. why is this? a3.
