java实现GroupBox
Java中没有GroupBox，要想实现类似VC中的GroupBox可以这样实现：

JPanel buttonPanel = new JPanel(new FlowLayout());
buttonPanel.setBorder(BorderFactory.createTitledBorder("Edit")); //设置边框
buttonPanel.add(new JButton("button1"));

为了方便布局，可以在页面中添加Panel控件，然后在Panel控件中设置边框

panel = new JPanel();
panel.setBounds(25, 10, 555, 141);
panel.setBorder(BorderFactory.createTitledBorder("边框")); //添加边框文字
frame.getContentPane().add(panel);
