本文實例為大家分享了java實現五子棋項目，供大家參考，具體內容如下

運行結果

視頻經過壓縮畫質略顯粗糙。

標題

1）繪制網格棋盤：

重寫JPanel的paint(Graphics g)方法，繪制16*16網格。如圖：

2）代碼如下（僅包含部分代碼）：

public class Board extends JPanel{ int width = Toolkit.getDefaultToolkit().getScreenSize().width; int height = Toolkit.getDefaultToolkit().getScreenSize().height; public HashMap<Point,Color> points=new HashMap<>();//存放已出的所有其中，方便繪圖和計算結果 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(); // 創建畫筆 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); //畫棋盤橫線 g1.drawLine(starX+i*step, starY, starX+i*step, Max+starY); //畫棋盤豎線 g1.setColor(Color.black); g1.setFont(new Font('楷體',Font.BOLD,15)); g1.drawString(numToCh(i),starX-((numToCh(i).length()==1)?25:35),starY+i*step+5);//縱行 g1.drawString(numToCh(i),starX+i*step-((numToCh(i).length()==1)?5:15),starY-8);//橫行 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<Point,Color> 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={'開始','悔棋','投降','幫助','重來'}; for(int i=0;i<str.length;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('宋體',Font.BOLD,35)); g1.drawString(str[i], 180+190*i, starY +Max+80);//縱行 } repaint(); }}
