新建一个chess类，其中代码如下
packagework;
importjava.awt.Color;
publicclassChess{
publicstaticfinalintdiamter=30;
privateintx;//在网格中的索引，0~15
privateinty;//在网格中的索引，0~15
privateColorcolor;
publicColorgetColor(){
returncolor;
}
publicvoidsetColor(Colorcolor){
this.color=color;
}
publicintgetX(){
returnx;
}
publicvoidsetX(intx){
this.x=x;
}
publicintgetY(){
returny;
}
publicvoidsetY(inty){
this.y=y;
}
publicChess(intx,inty,Colorcolor){
super();
this.x=x;
this.y=y;
this.color=color;
}
}
然后在同一个包中新建FirstFrame类。代码如下
packagework;
importjava.awt.event.ActionEvent;
importjava.awt.event.ActionListener;
importjavax.swing.JFrame;
importjavax.swing.JMenu;
importjavax.swing.JMenuBar;
importjavax.swing.JMenuItem;
//主函数
publicclassFirstFrame{
publicstaticvoidmain(String[]args){
FirstFrame1f=newFirstFrame1();
f.setVisible(true);
}
}
//窗体函数
classFirstFrame1extendsJFrameimplementsActionListener{
JMenuBarmenuBar;
JMenusysMenu;
JMenuItemstartMenuItem;
JMenuItembackMenuItem;
JMenuItemexitMenuItem;
DrawPanelmyPanel=newDrawPanel();
publicFirstFrame1(){
super(娃哈哈);
add(myPanel);
menuBar=newJMenuBar();
setJMenuBar(menuBar);
sysMenu=newJMenu(系统(s));
sysMenu.setMnemonic('s');
menuBar.add(sysMenu);
startMenuItem=newJMenuItem(开始);
backMenuItem=newJMenuItem(悔棋);
exitMenuItem=newJMenuItem(退出);
sysMenu.add(startMenuItem);
sysMenu.add(backMenuItem);
sysMenu.addSeparator();
sysMenu.add(exitMenuItem);
startMenuItem.addActionListener(this);
backMenuItem.addActionListener(this);
exitMenuItem.addActionListener(this);
super.setSize(600,650);
super.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
publicvoidactionPerformed(ActionEvente){
Objectobj=e.getSource();
if(obj==startMenuItem){
myPanel.start();//DrawPanelp=newDrawPanel();是错的；
}elseif(obj==backMenuItem){
myPanel.back();
}else{
System.exit(0);
}
}
}
最后新建一个DrawPanel类代码如下
packagework;
importjava.awt.Color;
importjava.awt.Cursor;
importjava.awt.Graphics;
importjava.awt.event.ActionEvent;
importjava.awt.event.ActionListener;
importjava.awt.event.MouseEvent;
importjava.awt.event.MouseListener;
importjava.awt.event.MouseMotionListener;
importjavax.swing.JFrame;
importjavax.swing.JMenu;
importjavax.swing.JMenuBar;
importjavax.swing.JMenuItem;
importjavax.swing.JOptionPane;
importjavax.swing.JPanel;
importsun.awt.geom.AreaOp.AddOp;
//画柄；
classDrawPanelextendsJPanelimplementsMouseListener,MouseMotionListener{
finalintMARGIN_TOP=60;
finalintMARGIN_LEFT=30;
finalintCELL_WIDTH=35;
finalintCOLS=15;
finalintROWS=15;
Chess[]chessList=newChess[(COLS+1)*(ROWS+1)];
intchessCount=0;
booleanisBlack=true;
booleangameOver=false;
publicDrawPanel(){//构造函数
Colorcolor=newColor(200,250,200);
setBackground(color);
this.addMouseMotionListener(this);
this.addMouseListener(this);
}
publicvoidstart(){
for(inti=0;i<chessList.length;i++)
chessList[i]=null;
isBlack=true;
gameOver=false;
chessCount=0;
repaint();
}
publicvoidback(){
if(chessCount==0||gameOver==true)
return;
chessList[chessCount-1]=null;
chessCount--;
isBlack=!isBlack;
repaint();
}
@Override
protectedvoidpaintComponent(Graphicsg){//方法重写
//TODOAuto-generatedmethodstub
super.paintComponent(g);
for(inti=0;i<=ROWS;i++){
g.drawLine(MARGIN_LEFT,MARGIN_TOP+i*CELL_WIDTH,MARGIN_LEFT+COLS*CELL_WIDTH,MARGIN_TOP+i*CELL_WIDTH);
}
for(inti=0;i<=COLS;i++){
g.drawLine(MARGIN_LEFT+i*CELL_WIDTH,MARGIN_TOP,MARGIN_LEFT+i*CELL_WIDTH,MARGIN_TOP+ROWS*CELL_WIDTH);
}
for(inti=0;i<chessCount;i++){//绘制棋子数组
Chesschess=chessList[i];
intxPos=MARGIN_LEFT+CELL_WIDTH*chess.getX()-Chess.diamter/2;
intyPos=MARGIN_TOP+CELL_WIDTH*chess.getY()-Chess.diamter/2;
g.setColor(chess.getColor());
g.fillOval(xPos,yPos,Chess.diamter,Chess.diamter);
if(i==chessCount-1){
g.setColor(Color.red);
g.drawRect(xPos,yPos,Chess.diamter,Chess.diamter);
}
}
if(isBlack)
g.setColor(Color.black);
else
g.setColor(Color.white);
g.fillOval(8*CELL_WIDTH,CELL_WIDTH/2,Chess.diamter,Chess.diamter);
StringcolorStr=isBlack==false?白方下:黑方下;
g.setColor(Color.blue);
g.drawString(colorStr+第+chessCount/2+步,9*CELL_WIDTH,CELL_WIDTH);
}
publicvoidmouseClicked(MouseEvente){}
publicvoidmouseEntered(MouseEvente){}
publicvoidmouseExited(MouseEvente){}
publicvoidmouseReleased(MouseEvente){}
publicvoidmouseDragged(MouseEvente){}
publicvoidmouseMoved(MouseEvente){

如果不行就hi我
