在这段java代码--俄罗斯方块，方块是怎么旋转的？
贴出来的代码还不够，不过已经基本能回答你的问题了。
我的推理过程：从(turnstate+1)%4可以看出，turnstate是一个数字，取值只有0、1、2、3，因此它仅仅是一个标识符，0、1、2、3四种取值分别标记着这个方块处于原状、旋转90度、180度或者270度。然后blow函数应该是一个判断旋转之后会不会出现和已有方块重叠的函数。
因此，这个turn函数的功能是：把标识符变成下一个状态，然后判断如果旋转，会不会和已有的方块重叠，如果重叠，就取消这个旋转标记的改变。
因此，答案就很明显了：真正实现旋转方块的操作并不在这里，或者说，你再仔细研究一下这个程序的代码，它可能实际上根本没有旋转过那个方块，只是用turnstate这个数字标记方块旋转了多少度，判断重叠以及绘制的时候才真正计算或者从表里直接读取旋转后状态而已。

用Java设计网络版俄罗斯方块会遇到哪些难点?
- 开发一个俄罗斯方块游戏。游戏者移动和旋转窗口内落下的方块，方块在一行堆满后就可以消掉，并得到相应的分数；如果方块堆积至窗口顶端，即告负。
- 在游戏程序中，我们可以将它看成3个对象，分别是程序窗体主类对象、方块数据管理对象、控制游戏自动下落的定时器线程对象、三个背景音乐对象。
- 开发工具：Sun NetBeans IDE 6.1。
- 游戏数据与界面显示相分离，用游戏结构数据描述游戏的状态，玩家操作或游戏自行走一步，程序中都通过修改游戏数据来体现，即每走一步，程序会修改当前的游戏数据，判断游戏是否结束了，也是通过对游戏数据的分析来作出结论。游戏界面是根据当时游戏数据来绘制的，当数据改变时，要清除原图形并重绘。总之，游戏的逻辑设计是针对游戏数据，而不是游戏界面。界面只是间接地向玩家显示结果。因此，在设计函数时，大致分二类：与玩家操作事件有关的数据处理函数，与界面效果有关的图形绘制函数。游戏运行过程由窗体监听到的键盘事件控制。
- 游戏窗体的设计视图中，选择“开始游戏”按钮，再右键点击“开始游戏”按钮，从菜单中选“事件”－＞“Action”事件类型－＞“actionPerformed”接口方法，将转到源视图中事件处理代码处，加入我们的处理代码，使得游戏开始。
- 功能：具有等级功能，不同的等级游戏的难度不一样；具有分数功能，消行可以得到分数；具有声音，有背景音和执行不同的操作出现不同的声音；具有设置功能，可以用来设置初始等级、开始行数、按键设置等。

java俄罗斯方块旋转算法,求解
可以给每一个小方块设置为一个坐标，变为一个三阶行列式，3*3矩阵，转变为二元数组旋转。观察一下左旋：
11 12 13 31 21 11
21 22 23 →→ 32 22 12
31 32 33 33 23 13
坐标变换如下：（1,1）变为（1,3），（1,2）变为（2,3），（1,3）变为（3,3） （2,1）变为（1,2），（2,2）变为（2,2），（2,3）变为（3,2） （3,1）变为（1,1），（3,2）变为（2,1），（3,3）变为（3,1） 规律就是（i,j）变为(j,3-i+1)： 如果是22的方格，就可以变为二阶行列式，也就是22的二元数组，这里给出3*3九宫格改变的示意，我的代码如下：
import java.util.Random;
public class T {
public static void main(String[] args) {
int[][] a = new int[3][3];
System.out.println("now begin to form a new integer array");
Random r = new Random();
for (int i = 0; i < 3; i++) {
for (int j = 0; j < 3; j++) {
a[i][j] = r.nextInt(10);
}
}
System.out.println("the array is shown as follows:");
for (int i = 0; i < 3; i++) {
for (int j = 0; j < 3; j++) {
System.out.print(a[i][j] + " ");
}
System.out.println();
}
System.out.println("左转九十度");
for (int i = 0; i < a.length; i++) {
for (int j = 0; j < a[i].length; j++) {
System.out.print(a[a[i].length - 1 - j][i] + " ");
}
System.out.println();
}
}
}
