我想在事件里用for循环按钮该怎么设置呢？

// 添加25个按钮到p1
        JButton[] pb = new JButton[25];
        int bn;
        for (bn=0;bn < 25; bn++){
            p1.add(pb[bn] = new JButton(new ImageIcon("./src/images/cm.jpg")));// 按钮图片        
        //监听者
        pb[bn].addActionListener(new ActionListener() {
            //监听事件
            public void actionPerformed(ActionEvent e) {
                pb[bn].setIcon(gw);
                pb[bn+1].setIcon(gw);
                pb[bn+5].setIcon(gw);
               
            }
        });}
