本文为大家分享了java画出五子棋游戏棋盘的方法，供大家参考，具体内容如下

棋盘模块：

画五子棋棋盘：19条横线、19条竖线

步骤一：显示棋盘

我有一张名为chessboard.png的棋盘，位置为根目录/res/drawable/chessboard/png，现在我要显示这张图片。

DrawChessBoard.java

package xchen.test.simpleGobang; 
 
import java.awt.Graphics; 
import java.awt.Image; 
import java.awt.Toolkit; 
 
import javax.swing.JPanel; 
public class DrawChessBoard extends JPanel{ 
 public Image boardImg; 
 public DrawChessBoard() { 
 boardImg = Toolkit.getDefaultToolkit().getImage("res/drawable/chessboard.png"); 
 if(boardImg == null) 
 System.err.println("png do not exist"); 
 } 
 @Override 
 protected void paintComponent(Graphics g) { 
 // TODO Auto-generated method stub 
 super.paintComponent(g); 
 
 int imgWidth = boardImg.getWidth(this); 
 int imgHeight = boardImg.getHeight(this); 
 int FWidth = getWidth(); 
 int FHeight= getHeight(); 
 
 int x=(FWidth-imgWidth)/2; 
 int y=(FHeight-imgHeight)/2; 
 g.drawImage(boardImg, x, y, null); 
 } 
}
