JFrame frame2 = new JFrame("Tauler Joc");

jb.setBounds(200,200,700,700);
panell.add(jb);
// Set image to size of JButton...
int offset = jb.getInsets().left;
jb.setIcon(resizeIcon(icon, jb.getWidth() - offset, jb.getHeight() - offset));
frame2.add(panell);
frame2.setDefaultCloSEOperation(JFrame.EXIT_ON_CLOSE);
如果只需要图像而没有边框，只需将offset变量设置为0或完全摆脱offset变量。
