How to set size of custom button?

I've created a GUI program with custom icons for buttons. I'm unable, however, to set the size of these buttons in Java, so they remain their original size, 230x227. I'm trying to get them to be around 20x20 so I used the following code:

classAlcBtn.setPreferredSize(new Dimension(20,20));
classAlcBtn.setIcon(new ImageIcon(getClass().getResource("Alchemist.png")));
classAlcBtn.setBorder(null);
classAlcBtn.setBorderPainted(false);
classAlcBtn.setContentAreaFilled(false);
classAlcBtn.setPressedIcon(
   new ImageIcon(getClass().getResource("alchemistClicked.png")));
classAlcBtn.setCursor(new Cursor(Cursor.HAND_CURSOR));

Is there a way to force these icons to size down, or do I have to size down the actual icon file? Thanks for any help.

Assuming you can size down the buttons, without icons. So use the following method to size down the image, without changing the size of original file:

 ImageIcon icon = new ImageIcon("whatever.jpg");
 Image img = icon.getImage() ;  
 Image newImg = img.getScaledInstance( NEW_WIDTH, NEW_HEIGHT,  java.awt.Image.SCALE_SMOOTH ) ;  
 icon = new ImageIcon( newImg );

 ...

 classAlcBtn.setIcon(icon);

And if Button resizing itself is not working, then you can try using setMaximumSize() instead of setPreferredSize() method as following:

classAlcBtn.setMaximumSize(new Dimension(100,100));

See this for more info. about sizes. Hope this Helps:)
