public class Test {
public static void main(String[] args) {
JFrame f=new JFrame();
//边缘空50
((JPanel)f.getContentPane()).setBorder(BorderFactory.createEmptyBorder(50,50,50,50));
//水平间隔120，垂直间隔80
f.getContentPane().setLayout(new GridLayout(3,3,120,80));
f.setSize(800,600);
for(int i=0; i<7; i++){
f.getContentPane().add(new JButton("bt "+String.valueOf(i+1)));
