 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....
