Java 五子棋人人对战和人机对战简单实现

废话不多说，咱直接进入正题

首先，为了方便，咱们先用一个Java接口把一些全局要用的数据写到接口里，这样就不用传来传去了

package wuziqi;public interface Gobang {public static final int size = 40; // 设置格子大小为40public static final int X = 20, Y = 20; // 设置棋盘右上角的位置public static final int coloum = 15; //设置行数public static final int row = 15; //设置列数public static final int[][] array1 = new int[coloum][row]; //记录棋子位置的数组public static final int[][] weightArray = new int[coloum][row]; //记录棋盘每个位置的权值public static final boolean flag[] = new boolean[2]; //记录选择的模式}

接下来，就是棋盘的实现了，由于棋盘要一开始就出现在界面上，并且要一直存在，不能消失，所以我们用重绘来画出棋盘

public void paint(Graphics g) {super.paint(g);for (int i = 0; i < coloum; i++) {g.drawLine(X, Y + size * i, X + size * (coloum - 1), Y + size * i);// 横线 //格子40g.drawLine(X + size * i, Y, X + size * i, Y + size * (coloum - 1));// 竖线 //格子40}}

这样我们就画好了棋盘，接下来我们要做的就是棋盘布局，加一些按钮。这里我用的是边界布局管理器（BorderLayout）把容器的的布局分为五个位置：CENTER、EAST、WEST、NORTH、SOUTH。依次对应为：上北（NORTH）、下南（SOUTH）、左西（WEST）、右东（EAST），中（CENTER）。

package wuziqi;import java.awt.BorderLayout;import java.awt.Color;import java.awt.Dimension;import java.awt.FlowLayout;import java.awt.Graphics;import javax.swing.ButtonGroup;import javax.swing.JButton;import javax.swing.JFrame;import javax.swing.JLabel;import javax.swing.JPanel;import javax.swing.JRadioButton;public class GobangMain extends JPanel implements Gobang {public static void main(String[] args) {GobangMain gm = new GobangMain();gm.initUI();}public void initUI() {JFrame frame = new JFrame("五子棋");frame.setSize(780, 635);frame.setDefaultCloseOperation(3);frame.setLocationRelativeTo(null);frame.setResizable(false);frame.setLayout(new BorderLayout());// 设置棋盘面板的背景颜色this.setBackground(Color.LIGHT_GRAY);// 将棋盘面板添加到窗体的中间部分frame.add(this, BorderLayout.CENTER);// 实例化JPanel面板对象，作为东边放置按钮的面板JPanel eastPanel = new JPanel();// 设置东边面板的布局方式为流式布局居中对齐eastPanel.setLayout(new FlowLayout());// 设置面板容器组件的宽度和高度eastPanel.setPreferredSize(new Dimension(150, 0));// 实例化单选按钮分组对象ButtonGroup bg = new ButtonGroup();// 定义数组，存储组件上要显示的文字信息String[] array = { "开始新游戏", "悔棋", "认输", "对战模式：", "人人对战", "人机对战" };for (int i = 0; i < array.length; i++) {if (i < 3) {JButton button = new JButton(array[i]);button.setPreferredSize(new Dimension(140, 80));eastPanel.add(button);} else if (i == 3) {JLabel label = new JLabel(array[i]);eastPanel.add(label);} else {JRadioButton button = new JRadioButton(array[i]);button.setSelected(false);bg.add(button);eastPanel.add(button);}}// 将eastPanel添加到窗体上的东边frame.add(eastPanel, BorderLayout.EAST);frame.setVisible(true);}public void paint(Graphics g) {super.paint(g);for (int i = 0; i < coloum; i++) {g.drawLine(X, Y + size * i, X + size * (coloum - 1), Y + size * i);// 横线 //格子40g.drawLine(X + size * i, Y, X + size * i, Y + size * (coloum - 1));// 竖线 //格子40}}}

贴上效果图：

界面写好了，接下来就是下棋了，因为要根据鼠标点击的位置来下棋和选择的模式进行人人对战和人机对战，所以这里我们要用到Java里面自带鼠标监(MouseAdapter)和动作监听(ActionListener),要把棋子画到棋盘上，自然还要用到画笔(Graphics)

package wuziqi;import java.awt.Color;import java.awt.Graphics;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.awt.event.MouseAdapter;import java.awt.event.MouseEvent;import java.util.Arrays;import javax.swing.JOptionPane;public class GobangListener extends MouseAdapter implements ActionListener,Gobang{private GobangMain gm; // 棋盘面板对象private Graphics g;// 画笔对象boolean cco=true;//记录下黑棋还是白棋boolean fff=true;//记录是否能悔棋boolean ggg=true; //记录是否能认输private MyArrayList<Chess> array;int coloum1,row1;int xx,yy,max;public GobangListener(GobangMain gm,MyArrayList<Chess> array) { //从GobangMain传窗体对象和记录棋子的数组this.gm = gm;this.array=array;}public void actionPerformed(ActionEvent e) {if (e.getActionCommand().equals("开始新游戏")) {for(int i=0;i<array1.length;i++) {Arrays.fill(array1[i], 0);}cco=true;fff=true;ggg=true;gm.addMouseListener(this);array.Reset();gm.repaint();}if (e.getActionCommand().equals("悔棋")) {if(flag[0]) { //人人对战悔棋if(fff) {if(array.getSize()>1) {array1[coloum1][row1]=0;Chess aaa=array.get(array.getSize()-2);coloum1=aaa.coloum;row1=aaa.row;array.Delete();cco=!cco;gm.repaint();}}}if(flag[1]) {//人机对战悔棋if(fff) {if(cco) {if(array.getSize()>2) {array1[xx][yy]=0;Chess aaa=array.get(array.getSize()-2);coloum1=aaa.coloum;row1=aaa.row;array.Delete();array1[coloum1][row1]=0;Chess bbb=array.get(array.getSize()-2);xx=bbb.coloum;yy=bbb.row;array.Delete();gm.repaint();}}}}}if (e.getActionCommand().equals("认输")) {if(ggg) {if(cco) {JOptionPane.showMessageDialog(gm, "白棋获胜");}else {JOptionPane.showMessageDialog(gm, "黑棋获胜");}gm.removeMouseListener(this);fff=false;ggg=false;}}if (e.getActionCommand().equals("人人对战")) { //选择人人对战模式 flag[0]为true,flag[1]为falseflag[0]=true;flag[1]=false;for(int i=0;i<array1.length;i++) {Arrays.fill(array1[i], 0);}cco=true;fff=true;ggg=true;array.Reset();gm.repaint();}if (e.getActionCommand().equals("人机对战")) { //选择人机对战模式 flag[0]为false,flag[1]为trueflag[0]=false;flag[1]=true;for(int i=0;i<array1.length;i++) {Arrays.fill(array1[i], 0);}cco=true;fff=true;ggg=true;array.Reset();gm.repaint();}}public void mouseReleased(MouseEvent e) {//鼠标松开的时候进行的操作if(flag[0]) { //选择人人对战模式进行的操作if (g == null)g = gm.getGraphics();int x = e.getX();int y = e.getY();coloum1 = (x-X+size/2)/size; row1 = (y-Y+size/2)/size;if(coloum1<coloum&&row1<row) {if(array1[coloum1][row1]==0) {if(cco) {g.setColor(Color.BLACK);g.fillOval(X+coloum1*size-size/2, Y+row1*size-size/2, size, size);array1[coloum1][row1]=1;Chess sh=new Chess(coloum1,row1,Color.BLACK); //创建棋子对象，将棋子的信息存储array.add(sh); //将棋子加入数组队列}else {g.setColor(Color.WHITE);g.fillOval(X+coloum1*size-size/2, Y+row1*size-size/2, size, size);array1[coloum1][row1]=-1;Chess sh=new Chess(coloum1,row1,Color.WHITE);array.add(sh);}Judge jd=new Judge(coloum1,row1);if(jd.judge()) {if(cco) {JOptionPane.showMessageDialog(gm, "黑棋获胜");}else {JOptionPane.showMessageDialog(gm, "白棋获胜");}gm.removeMouseListener(this);fff=false;ggg=false;}cco=!cco;}}}if(flag[1]) { //选择人机对战进行的操作if (g == null)g = gm.getGraphics();if(cco) { //若coo为true，则人下棋int x = e.getX();int y = e.getY();coloum1 = (x-X+size/2)/size; row1 = (y-Y+size/2)/size;if(coloum1<coloum&&row1<row) {if(array1[coloum1][row1]==0) {g.setColor(Color.BLACK);g.fillOval(X+coloum1*size-size/2, Y+row1*size-size/2, size, size);array1[coloum1][row1]=1;Chess sh=new Chess(coloum1,row1,Color.BLACK);array.add(sh);Judge jd=new Judge(coloum1,row1);if(jd.judge()) {if(cco) {JOptionPane.showMessageDialog(gm, "黑棋获胜");}else {JOptionPane.showMessageDialog(gm, "白棋获胜");}gm.removeMouseListener(this);fff=false;ggg=false;cco=!cco;}cco=!cco;}}}if(!cco) { //若coo为false，则机器下棋AIX();}}}public void AIX() {for(int i=0;i<weightArray.length;i++) {for(int j=0;j<weightArray[i].length;j++) {weightArray[i][j]=0;}}max=-1;AI.Quan(); for(int i=0;i<weightArray.length;i++) {for(int j=0;j<weightArray[i].length;j++) {if(i<5&&j<5) {if(max<=weightArray[i][j]&&array1[i][j]==0) {max=weightArray[i][j];xx=i;yy=j;}}else {if(max<weightArray[i][j]&&array1[i][j]==0) {max=weightArray[i][j];xx=i;yy=j;}}}}if(array1[xx][yy]==0) {g.setColor(Color.WHITE);g.fillOval(X+xx*size-size/2, Y+yy*size-size/2, size, size);array1[xx][yy]=-1;Chess sh=new Chess(xx,yy,Color.WHITE);array.add(sh);Judge jd=new Judge(xx,yy);if(jd.judge()) {if(cco) {JOptionPane.showMessageDialog(gm, "黑棋获胜");}else {JOptionPane.showMessageDialog(gm, "白棋获胜");}gm.removeMouseListener(this); //移除监听，这时将不能对棋盘进行操作fff=false; //设置不能进行悔棋ggg=false; //设置不能进行认输}cco=!cco;}}}

棋子类

package wuziqi;import java.awt.Color;public class Chess extends Object implements Gobang{int coloum,row;Color color;public Chess(int coloum,int row,Color color) {this.coloum=coloum;this.row=row;this.color=color;}}

这个是我自己写的一个数组队列

package wuziqi;public class MyArrayList<E> {public Object[] array;private int size=0;public MyArrayList() {array =new MyArrayList[0];}public void add(E e) {Object[] a =new Object[array.length+1];for(int i=0;i<array.length;i++) {a[i]=array[i];}a[array.length]=e;array=a;size++;}@SuppressWarnings("unchecked")public E remove(int index) {if(index<=0||index>size) return null;Object[] a=new Object[array.length-1];for(int i=0;i<index;i++) {a[i]=array[i];}Object e=array[index];for(int i=index;i<a.length;i++) {a[i]=array[i+1];}array=a;return (E)e;}public void Delete() {Object[] a=new Object[array.length-1];for(int i=0;i<array.length-1;i++) {a[i]=array[i];}array=a;size--;}public int getSize() {return size;}public void setA(int i) {array[i]=null;}@SuppressWarnings("unchecked")public E get(int index) {Object e=array[index];return (E)e;}public void Reset() {Object[] a =new Object[0];size=0;array =a;}}

这时候运行代码，一点棋盘发现并没有反应，这是因为没有加上监听，这是需要在GobangMain里面对按钮加上监听，在for循环前面加上GobangListener gl = new GobangListener(this, array); 在eastPanel.add(button);后面加上button.addActionListener(gl)

现在可以下棋了，接下来就是判断输赢和人机算法了，判断输赢我用的是便利所有的棋子进行判断，有五个连在一起就结束游戏，人机算法我用的是比较垃圾的权值法，这个有点蠢，当然还有更好的博弈论算法、和机器学习算法，有兴趣的可以自行去了解

接下来贴出所有代码

接口类
