import java.awt.Image;
/**
* 格子
* 每一个小格子，就有所在的行 列 和图片
*/
public class Cell {
private int row;
private int col;
//private int color;

}

}

}
public void setRow(int row) {

return col;
}
public void setCol(int col) {

}
public Image getImage() {
return image;
}
public void setImage(Image image) {

}
public void moveRight(){
col++;
//System.out.println("Cell moveRight()" + col);
}
public void moveLeft(){
col--;
}
public void moveDown(){
row++;
}
@Override
public String toString() {
return "["+row+","+col+"]";
