画五子棋棋盘：19条横线、19条竖线

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); 
 } 
}

Main.java

package xchen.test.simpleGobang; 
 
import java.awt.Container; 
import javax.swing.JFrame; 
 
import xchen.test.simpleGobang.DrawChessBoard; 
 
public class Main extends JFrame{ 
 private DrawChessBoard drawChessBoard; 
 public Main() { 
 drawChessBoard = new DrawChessBoard(); 
 
 //Frame标题 
 setTitle("单机五子棋"); 
 
 Container containerPane =getContentPane(); 
 containerPane.add(drawChessBoard); 
 } 
 public static void main(String[] args) { 
 Main m = new Main(); 
 m.setVisible(true); 
 } 
}

运行一下

步骤二：为棋盘画上横竖线

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; 
 final private int ROWS = 19; 
 public DrawChessBoard() { 
 boardImg = Toolkit.getDefaultToolkit().getImage("res/drawable/chessboard2.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); 
 
 int margin = x; 
 int span_x=imgWidth/ROWS; 
 int span_y=imgHeight/ROWS; 
 //画横线 
 for(int i=0;i

Main.java不变
