JButton b3 = new JButton(new ImageIcon("e:/project/j2se/3.jpg"));
JButton b4 = new JButton(new ImageIcon("e:/project/j2se/4.jpg"));
JButton b5 = new JButton(new ImageIcon("e:/project/j2se/5.jpg"));
JButton b6 = new JButton(new ImageIcon("e:/project/j2se/6.jpg"));
tb.add(b1);
tb.add(b2);
tb.add(b3);
tb.add(b4);
tb.add(b5);
tb.add(b6);
// 把工具栏放在north的位置
f.setLayout(new BorderLayout());
f.add(tb, BorderLayout.NORTH);

tb.add(b4);
tb.add(b5);
tb.add(b6);
// 给按钮设置提示信息
b1.setToolTipText("坑爹英雄");
// 把工具栏放在north的位置
f.setLayout(new BorderLayout());
f.add(tb, BorderLayout.NORTH);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setVisible(true);
