  class WindGrid extends JFrame
  {
      final int maxn =12;
      GridLayout grid;  //设置一个网络对象
      JPanel myjpanel;  //设置一个画板Jpanel
      Label  myLabel[][] ;
      public WindGrid()
      {
          grid = new GridLayout(12,12);  //设置行列
          myjpanel = new JPanel();
          myjpanel.setLayout(grid);
          myLabel = new Label [maxn][maxn];
          for(int i=0;i<maxn ;i++)
          {
             for(int j=0 ; j<maxn ;j++)
             {
                 myLabel[i][j] = new Label("Gxjun");
              //设置背景颜色
               if((i+j)%2==0)
                   myLabel[i][j].setBackground(Color.black);
               else
                   myLabel[i][j].setBackground(Color.white);
                 myjpanel.add(myLabel[i][j]); //将标签放置到面板上去
             }
          }
          add(myjpanel,BorderLayout.CENTER);
          //添加几个按钮
           JButton mybutton;
           mybutton=new JButton("北方参战国");
           mybutton.setSize(2,3);
           add(mybutton,BorderLayout.NORTH);

          setTitle("国际象棋");
          setBounds(10,10,310,290);
          setVisible(true);
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);  //注销程序
          validate();  //可法即可执行
      }
  }

  public class test
  {
      public static void main(String [] args)
      {
          new WindGrid();
      }
  }

面板控制一般需要用到setLayout ,GridLayout 这两个类....
