tfidf的计算的java实现，程序结构清晰，注释易懂,(java tfidf calculated to achieve a clear program structure, comments to understand,)

一个SSH框架的模板，上面有修改的资料。(a template for SSH.)

猜数字游戏 游戏说明: 1、游戏开始，电脑随机产生一个数字不重复的四位数。 2、将您猜的数点击OK按钮提交。 3、电脑会将您提交的数与它自动产生的数进行比较，结果显示成"*A*B"。A代表位置正确数字也正确，B代表数字 正确但位置不正确，比如："2A2B"表示您有2个数字的位置正确且数值也正确，除此以外，您还猜对了2个数字 ，但位置不对。 4、您共有10次机会，在10次内，如果结果为“4A0B”，游戏成功。如果10次里您都没有猜对游戏失败。(Guessnumber: 1, games started, the computer randomly generated a number of non-repetition of the four-digit. 2, would you guess the number of clicks the OK button to submit. 3, the computer will take you to submit a few with it automatically generated a number of comparison, the result is displayed as* A* B . A representative of the location of the correct figure is also correct, B representative of the number of correct but the location is incorrect, such as: 2A2B that you have a two-digit numerical position is correct and also the right, in addition, you guessed it two figures, but wrong location. 4, your opportunity for a total of 10 times in 10 times, if the results of 4A0B , the game successfully. 10 years if you do not have to guess the failure of the game.)

说明：  前端框架基础，demo可供参考，请不要随意转载，(String to JSON, object to JSON)

说明：  java基础学习资料（含Notepad++和源代码）(Java basic learning materials (including Notepad++ and source code))

说明：  编写一个复数类，可以进行复数加法和减法运算。编写一个包含main方法的类（应用程序）测试该复数类。要求该复数类至少包含一个无参的构造方法和一个带参的构造方法；数据成员包括复数的实部和虚部，为double类型；包括两个方法，分别实现复数的加法和减法运算。(Write a complex class, which can add and subtract complex numbers. Write a class (application) containing the main method to test the complex class. The complex class is required to include at least one parametric construction method and one parametric construction method; the data members include the real and imaginary parts of the complex, which are of double type; and two methods are included to realize the addition and subtraction operations of the complex respectively.)

随机产生数据，输入大小值，大了或小了都有显示。还可以继续玩，如果猜对的话，也可以退出 (Randomly generated data, the value of the input size, big or small are displayed. Can continue to play, if you guess right, you can exit)

说明：  支持中英文一键切换，备份和还原MS数据库，客户端调用Jasper模板打印pdf(Support one-click switch between Chinese and English, backup and restore MS database, client calls Jasper template to print pdf)

java学习书籍，java设计模式，适用于初学者，，内容详细丰富(java learning books)

里面有几个不错的学习资源链接，包括OC、cocos、java等，希望有帮助。(There are several good links to learning resources, including OC, cocos, Java, hope that helps.)
