How to get the position of JButton?

Question

I want to get the position of the JButton to have the return a value. I need the value to print out the element in an array list. I have ten elements in the array list. A GridLayout(0,2) was used to layout the buttons.

So what should I do?

                 for(int i=0;i<item.size();i++)
                {
                    JButton btn1= new JButton(item.get(i).print());

                    btn1.setPreferredSize(new Dimension(300,40));

                    panel2.setLayout(new GridLayout(0,2));

                    panel2.add(btn1, BorderLayout.NORTH);

                    content.add(panel2, BorderLayout.NORTH);

                }
            public Food selectFood(int input)
            {

                int get=0;

                if(input>0 && input< 11)
                {
                     item.get(input-1);

                }

want to get the position as an input to print the selected item.

Are you looking for the button's [grid location](http://stackoverflow.com/q/7702697/230513) or it's pixel coordinates? — trashgod, Nov 23 '12 at 03:07
As a general tip. If you need a reference to a GUI control, keep a reference rather than 'hunting' for the control later. — Andrew Thompson, Nov 23 '12 at 03:17

I remember that it can use JButton.getBounds() function, then it can use JButton.getBounds().x and JButton.getBounds().y to get its upper-left corner position.

For just the position, then `JButton#getLocation()` is adequate, as it returns the x, y Point that represents the component's location in its container. – Hovercraft Full Of Eels Nov 23 '12 at 03:09
you should use getX and getY because it does not cause heap allocations. – Ungeheuer Jun 07 '15 at 22:55
