Object-Oriented Programming

Class detail Design:

1. Create a chessboard class, draw the style of the board, add various buttons on the board panel and corresponding HU trigger events. At the same time pay attention to the design of the panel, so that the panel design as far as possible reasonable beauty.

A. Drawing of the Chessboard

public void Draw_qipan (Graphics G)// Draw Board 15*15{

G.setcolor (Color.lightgray);

G.fill3drect (10,10,300,300,true);

G.setcolor (Color.Black);

for (int i=1;i<16;i++) {

G.drawline (20,20*i,300,20*i);

G.drawline (20*i,20,20*i,300);

}

}

B. Add button and button Hu plan

Button B1=new button (" start ");

Button B2=new button (" Reset game ");

Label Lblwin=new label ("");

Checkbox Ckbhb[]=new checkbox[3];

button exist = New button (" exit ");

public void init () {

Ckbhb[0]=new Checkbox (" white ", Ckghb,false);

Ckbhb[1]=new Checkbox (" black ", Ckghb,false);

Ckbhb[2]=new Checkbox (" watch ", CKGHB, false);

}

C. Mouse piece hu corresponding Trigger event

public void mouseclicked (MouseEvent e) {

Graphics G=getgraphics ();

int x1,y1;

X1=e.getx ();

Y1=e.gety ();

if (E.getx () <20 | | e.getx () >300 | | e.gety () <20 | | e.gety () >300) {

Return

}

if (x1%20>10) {

x1+=10;

}

if (y1%20>10) {

y1+=10;

}

x1=x1/20*20;

y1=y1/20*20;

Set_qizi (X1,Y1);

m*= (-1);

}

D. trigger events for buttons

public void actionperformed (ActionEvent e) {

Graphics G=getgraphics ();

if (E.getsource () ==b1) {

Game_start ();

}

else{

Game_re ();

}

if (E.getsource () ==exist) {

Game_re ();

Lblwin.settext (Get_qizi_color (Color_qizi) + " lost !");

intgame_start=0;

}

2. Write a function to judge the position of the Lazi and draw the corresponding black and white pieces

public void Set_qizi (int x,int y)//Lazi {

if (intgame_start==0)//judgment game not started {

Return

}

if (intgame_body[x/20][y/20]!=0) {

Return

}

Graphics G=getgraphics ();

if (color_qizi==1)//Determine the sunspot or the white child {

G.setcolor (Color.Black);

color_qizi=0;

}

else{

G.setcolor (Color.White);

Color_qizi=1;

}

G.filloval (x-10,y-10,20,20);

intgame_body[x/20][y/20]=color_qizi+1;

｝

3. Judging the outcome

if (game_win_1 (X/20,Y/20))// judgment win or lose 1{

Lblwin.settext (Get_qizi_color (Color_qizi) + " won !");

intgame_start=0;

}

if (Game_win_2 (X/20,Y/20))// judgment win or lose 2{

Lblwin.settext (Get_qizi_color (Color_qizi) + " won !");

intgame_start=0;

}

if (Game_win_3 (X/20,Y/20))// judgment win or lose 3{

Lblwin.settext (Get_qizi_color (Color_qizi) + " won !");

intgame_start=0;

}

if (Game_win_4 (X/20,Y/20))// judgment win or lose 4{

Lblwin.settext (Get_qizi_color (Color_qizi) + " won !");

intgame_start=0;

}  }

Specific implementation

1. Create a Board class

public class Wcychess extends Applet implements actionlistener,mouselistener,mousemotionlistener,itemlistener{

int color_qizi=0;//flag Color Identification 0: White sub 1: Sunspots

int intgame_start=0;//game start Flag 0 not started 1 in-game

int intgame_body[][]=new int[16][16]; Set the board piece status

int m=-1;

Button B1=new button ("Start");

Label Lblwin=new label ("");

Checkbox Ckbhb[]=new checkbox[3];

button exist = New button ("Exit");

CheckboxGroup ckghb=new CheckboxGroup ();

public void init () {

Ckbhb[2].setbounds (440, 20, 60, 30);

Add (exist);

Exist.addactionlistener (this);

Add (chat); Chat.setbounds (20, 500, 300, 300);

Chat.frame ();

Chat.setvisible (TRUE);

GAME_START_CSH ();

SetSize (500,600);

public void mousereleased (MouseEvent e) {}

public void mousedragged (MouseEvent e) {}

2 The realization of judging and losing function

if (game_win_1 (X/20,Y/20)) {//Judge win or lose 1

Lblwin.settext (Get_qizi_color (Color_qizi) + " won !");

intgame_start=0;

}

Lblwin.settext (Get_qizi_color (Color_qizi) + " won !");

intgame_start=0;

}

if (Game_win_3 (X/20,Y/20))// judgment win or lose 3{

Lblwin.settext (Get_qizi_color (Color_qizi) + " won !");

intgame_start=0;

}

if (Game_win_4 (X/20,Y/20))// judgment win or lose 4{

Lblwin.settext (Get_qizi_color (Color_qizi) + " won !");

intgame_start=0;

}
