我负责的主要部分为各个按钮的实现与控制以及倒计时的设置。

（1）各个按钮的实现与控制

其中的难点在于每个按钮的使用过程中都是有一些联系的，不然会出现意想不到的bug。例如“认输”按钮后面canPlay = false；会影响接下来的使用，会使认输之后再重新开始后不能落子，所以必须在每一个有重新开始功能的按钮下加入canPlay = true；

allChess = new int【19】【19】作用就是清空棋盘。注：【19】【19】应该为【15】【15】否则会出现bug。

 if(e.getX() >=678 && e.getX() <=838 && e.getY() >=50 && e.getY() <=115){int result = JOptionPane.showConfirmDialog(this, "是否重新开始游戏？");if(result == 0) {allChess = new int [19][19];isBlack = true;canPlay = true;blackTime = maxTime;whiteTime = maxTime;if(maxTime > 0) {blackMessage = maxTime/3600+":"+(maxTime/60-maxTime/3600*60)+":"+(maxTime-maxTime/60*60);whiteMessage = maxTime/3600+":"+(maxTime/60-maxTime/3600*60)+":"+(maxTime-maxTime/60*60);}else {blackMessage = "无限制";whiteMessage = "无限制";}t.resume();this.repaint();}}if(e.getX() >=678 && e.getX() <=838 && e.getY() >=134 && e.getY() <=194){String input = JOptionPane.showInputDialog("请输入最大游戏时间(分钟)，如果输入0则表示没有时间限制:");try {maxTime = Integer.parseInt(input) * 60;if(maxTime < 0) {JOptionPane.showMessageDialog(this, "请输入正确信息，不允许时负数！");}if(maxTime == 0) {int result = JOptionPane.showConfirmDialog(this, "设置完成，是否重新开始游戏？");if(result == 0) {allChess = new int [19][19];isBlack = true;canPlay = true;blackTime = maxTime;whiteTime = maxTime;blackMessage = "无限制";whiteMessage = "无限制";this.repaint();}}if(maxTime > 0) {int result = JOptionPane.showConfirmDialog(this, "设置完成，是否重新开始游戏？");if(result == 0) {allChess = new int [19][19];isBlack = true;canPlay = true;blackTime = maxTime;whiteTime = maxTime;blackMessage = maxTime/3600+":"+(maxTime/60-maxTime/3600*60)+":"+(maxTime-maxTime/60*60);whiteMessage = maxTime/3600+":"+(maxTime/60-maxTime/3600*60)+":"+(maxTime-maxTime/60*60);t.resume();this.repaint();}}}catch(NumberFormatException el) {JOptionPane.showMessageDialog(this, "请输入正确信息！");}}if(e.getX() >=678 && e.getX() <=838 && e.getY() >=215 && e.getY() <=274){int result = JOptionPane.showConfirmDialog(this,"是否确认 认输？" );if(result == 0) {if(isBlack) {JOptionPane.showMessageDialog(this, "黑方已经认输，游戏结束！");canPlay = false;}else{JOptionPane.showMessageDialog(this, "白方已经认输，游戏结束！");canPlay = false;}}				 }

（2）倒计时的设置

前面的声明定义就不展示了，设计倒计时的重点之一就是，要让倒计时结束时停止计时，要用到t.stop() (当然这类方法已经过时了但是其他的不会用) 并且要在此之前加入canPlay = false；否则计时结束分出胜负后依然能下棋。

if(maxTime > 0) {while(true) {if(isBlack) {blackTime-- ;if(blackTime == 0) {JOptionPane.showMessageDialog(this, "黑方超时，游戏结束");canPlay = false;t.stop();}}else {whiteTime-- ;if(whiteTime == 0) {JOptionPane.showMessageDialog(this, "白方超时，游戏结束");canPlay = false;t.stop();}}try {Thread.sleep(1000);}catch (InterruptedException e) {e.printStackTrace();}blackMessage = blackTime/3600+":"+(blackTime/60-blackTime/3600*60)+":"+(blackTime-blackTime/60*60);whiteMessage = whiteTime/3600+":"+(whiteTime/60-whiteTime/3600*60)+":"+(whiteTime-whiteTime/60*60);this.repaint();System.out.println(blackTime + "--"+whiteTime);}}

其他的bug暂时没发现，第一次写程序练手多多包涵！ 

效果如下：

背景图片为江流儿（网图），各位可以自行设计背景图片。这个程序会出现屏闪问题，目前也不会修复，还请各位大佬指点。
