二、Cell.java

package com.fry.tetris;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; private Image image;//格子的贴图 public Cell() { } public Cell(int row, int col, Image image) { super(); this.row = row; this.col = col; this.image = image; } public int getRow() { return row; } public void setRow(int row) { this.row = row; } public int getCol() { return col; } public void setCol(int col) { this.col = col; } public Image getImage() { return image; } public void setImage(Image image) { this.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+"]"; }}
