[实验任务一]：围棋
设计一个围棋软件，在系统中只存在一个白 棋对象和一个黑棋对象，但是它们可以在棋盘的不同位置显示多次。
实验要求：
1. 提交类图；
2. 提交源代码；
package test;
public class BlackPiece extends Piece{
@Override
public String getColor() {
// TODO Auto-generated method stub
return "黑棋";
}
}
package test;
public class WhitePiece extends Piece{
@Override
public String getColor() {
// TODO Auto-generated method stub
return "白棋";
}
}
package test;
public abstract class Piece {
public abstract String getColor();
public void locate(Location lo) {
System.out.println(this.getColor()+" "+lo.getX()+","+lo.getY());
}
}
package test;
public class PieceFactory {
private static PieceFactory instance=new PieceFactory();
private static Piece wp=new WhitePiece();
private static Piece bp=new BlackPiece();
public PieceFactory() {
// TODO Auto-generated constructor stub
//instance=new PieceFatory();
//Piece wp=new WhitePiece();
//Piece bp=new BlackPiece();
}
public static PieceFactory getInstance() {
return instance;
}
public static Piece getPiece(String color) {
if(color.equals("白棋")) {
return wp;
}else {
return bp;
}
}
}
package test;
public class Location {
private String x;
private String y;
public Location(String x,String y) {
// TODO Auto-generated constructor stub
this.x=x;
this.y=y;
}
public String getX() {
return x;
}
public String getY() {
return y;
}
public void setX(String x) {
this.x=x;
}
public void setY(String y) {
this.y=y;
}
}
package test;
public class Client {
public static void main(String[]args) {
Piece b1,b2,b3,w1,w2,w3;
PieceFactory pf;
pf=PieceFactory.getInstance();
b1=pf.getPiece("黑棋");
b2=pf.getPiece("黑棋");
System.out.println("判断两颗黑棋是否相同："+(b1==b2));
w1=pf.getPiece("白棋");
w2=pf.getPiece("白棋");
System.out.println("判断两颗白棋是否相同："+(w1==w2));
b1.locate(new Location("1","2"));
b2.locate(new Location("3","2"));
w1.locate(new Location("10","2"));
w2.locate(new Location("1","21"));
}
}
3.注意编程规范；
4.要求用简单工厂模式和单例模式实现享元工厂类的设计。
