用java画国际象棋棋盘

        用java画了一个国际象棋的棋盘，不难，还是挺好玩的。

package com.test;

import java.awt.BorderLayout;
import java.awt.Color;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.UIManager;

public class Chess extends JFrame {


private static final long serialVersionUID = 1L;

JPanel jp=new JPanel();

    public Chess(int gridSize){

    //这句忘加可不行
    jp.setLayout(null);
    for(int i=0;i<8;i++)
    for(int j=0;j<8;j++)
    {
    Color color=Color.white;
    JLabel label=new JLabel();
        label.setSize(gridSize, gridSize);
        label.setLocation(i*gridSize, j*gridSize);
        if((i+j)%2==0)
         color=Color.black;

        label.setOpaque(true);
        label.setBackground(color);
        //设置边界线为黑色
        label.setBorder(BorderFactory.createLineBorder(Color.black));
        jp.add(label);
        //Jpanel加在JFrame上
        add(jp, BorderLayout.CENTER);
    }
    }

public static void main(String[] args) {

try {
//用当前系统的窗口风格
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());  
}catch (Exception e) {
e.printStackTrace();
}
         Chess chessBord=new Chess(100);
         chessBord.setSize(810,835);
         //加上这句可以让窗口居中
         chessBord.setLocationRelativeTo(null);
         chessBord.setVisible(true);
         chessBord.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}
}
