I set the minimum and maximum size of two buttons with code like:

			

			JButton addOneB = new JButton("Add");
			

			addOneB.setMinimumSize(buttonSize);
			

			addOneB.setMaximumSize(buttonSize2);
			

		

buttonSize = buttonSize2 = {200,30}.

Still the two buttons show up with different sizes.
Their sizes depend on their labels, while the min and the max assignments are simply ignored.

What is going on here?
