本文实例为大家分享了java实现五子棋项目，供大家参考，具体内容如下
运行结果
视频经过压缩画质略显粗糙。

1)绘制网格棋盘：
重写JPanel的paint(Graphics g)方法，绘制16*16网格。
如图：
2)代码如下(仅包含部分代码)：
public class Board extends JPanel{
int width = Toolkit.getDefaultToolkit().getScreenSize().width;
int height = Toolkit.getDefaultToolkit().getScreenSize().height;
public HashMap points=new HashMap<>();//存放已出的所有其中，方便绘图和计算结果
Board(){
this.setVisible(true);
drawBoard();
}
public int starX=300,starY=40,step=40,piecesR=28;
BufferedImage buf;
@Override
public void paint(Graphics g){
g.drawImage(buf, 0, 0,this);
}
void drawL(Point p,Graphics2D g1,int length,int bound){
int x1=p.x-bound;
int x2=p.x-bound-length;
int x3=p.x+bound;
int x4=p.x+bound+length;
int y1=p.y-bound;
int y2=p.y-bound-length;
int y3=p.y+bound;
int y4=p.y+bound+length;
g1.drawLine(x1,y1,x2,y1);
g1.drawLine(x1,y1,x1,y2);
g1.drawLine(x1,y3,x2,y3);
g1.drawLine(x1,y3,x1,y4);
g1.drawLine(x3,y3,x3,y4);
g1.drawLine(x3,y3,x4,y3);
g1.drawLine(x3,y1,x4,y1);
g1.drawLine(x3,y1,x3,y2);
}
public void drawBoard(){
int Max=step*15;
buf = new BufferedImage(this.width, this.height, BufferedImage.TYPE_INT_RGB);
Graphics2D g1 = buf.createGraphics(); // 创建画笔
g1.addRenderingHints((Map)(Toolkit.getDefaultToolkit().getDesktopProperty("awt.font.desktophints")));
g1.setColor(new Color(46,139,87));//60,179,113//0,255,127
g1.fillRect(0,0,this.width,this.height);
g1.setColor(new Color(106,90,205));
g1.fill3DRect(starX, starY, Max, Max, true);
for (int i = 0; i <=15; i++) {
g1.setColor(Color.WHITE);
g1.drawLine(starX, starY+i*step, Max+starX, starY+i*step); //画棋盘横线
g1.drawLine(starX+i*step, starY, starX+i*step, Max+starY); //画棋盘竖线
g1.setColor(Color.black);
g1.setFont(new Font("楷体",Font.BOLD,15));
g1.drawString(numToCh(i),starX-((numToCh(i).length()==1)?25:35),starY+i*step+5);//纵行
g1.drawString(numToCh(i),starX+i*step-((numToCh(i).length()==1)?5:15),starY-8);//横行
g1.setColor(Color.BLACK);
g1.setStroke(new BasicStroke(2.0f));
if(i==4) {
drawL(new Point(starX+i*step,starY+i*step),g1,8,4);
drawL(new Point(starX+i*step,starY+12*step),g1,8,4);
}
if(i==12){
drawL(new Point(starX+i*step,starY+i*step),g1,8,4);
drawL(new Point(starX+i*step,starY+4*step),g1,8,4);
}
Iterator iterator=points.entrySet().iterator();
while(iterator.hasNext()){
Map.Entry entry=(Map.Entry)iterator.next();
g1.setColor(entry.getValue());
g1.fillOval(starX+(entry.getKey().x)*step-17,starY+(entry.getKey().y)*step-17,34,34);
}
String []str={"开始","悔棋","投降","帮助","重来"};
for(int i=0;i
g1.setColor(Color.white);
g1.fillRect(140+190*i, starY +Max+45, 150, 50);
g1.setColor(Color.black);
g1.setStroke(new BasicStroke(50.0f));
g1.setFont(new Font("宋体",Font.BOLD,35));
g1.drawString(str[i], 180+190*i, starY +Max+80);//纵行
}
repaint();
}
}
