《DWR实战》书评

这本书很赞

作者学识动手都很强，还很humor，只是基础内容有些偏少，可能是因为DWR本身内容就不多吧，我是初学，看了前几章，很清楚了。后面的projects实战也不错，运用到了多种技术。

作者的算法水平呀

书的内容挺不错的，也很有趣。不过第7章和第9章的例子貌似没有给出登录的用户名和密码，以至于只能看看登录界面。另外作者的算法水平实在是不敢恭维。下面这个例子摘自书中第8章。21种卡片，每种两张，一共是42张，这个函数是用来产生随机初始排列的。int[] generateGrid() {// The grid of tiles.int[] grid = new int[42];// Record which tiles have been randomly set already.HashMap<Integer, Object> tilesSetAlready = new HashMap<Integer, Object>();// There are 21 tile types to set, i.e., 21 pairs.for (int i = 1; i < 22; i++) {Random generator = new Random();// Pick one tile, and keep doing it until one that isn't set is found.int tile1 = generator.nextInt(42);while (tilesSetAlready.get(new Integer(tile1)) != null) {tile1 = generator.nextInt(42);}// Pick another tile, and keep doing it until one that isn't set is found.tilesSetAlready.put(new Integer(tile1), new Object());int tile2 = generator.nextInt(42);while (tilesSetAlready.get(new Integer(tile2)) != null) {tile2 = generator.nextInt(42);}tilesSetAlready.put(new Integer(tile2), new Object());// Set the tiles to the next tile type.grid[tile1] = i;grid[tile2] = i;}return grid;}
