java - tic tac toe game project image icon? -


i making tic tac toe project, , using 9 buttons , images(circle.jpg , cross.jpg). first of all, wanna clear 1 thing guys, first made game using letter ("x"), ("o"), using images game , computer vs player game after running, when clicked on button show's me cross on button, that's right, , computer automatically puts circle in button!

the problem when click next button, shows me cross, correct. computer not put circle block row.

}

}

this looks wrong me 

 buttons[1].gettext().equals(image)

you comparing text image, doubt can ever true.

it should be

 buttons[1].geticon() == image

that work if load image once , use everywhere comparing object reference.
