录音显示波形

本书是Rod Johnson写的J2ee without EJB的第一章。(The book is written by Rod Johnson)

使用java实现的最简单的客户-服务器程序，实现了两者之间的交互，可以在此基础上完成多种操作。(java use of the most simple client-server procedures, the interaction between the two. This can be completed on the basis of a variety of operation.)

实现一个程序，对用户输入的类权限、成员权限、以及使用该类对象的环境与这个类的关系，判断这个环境中能不能访问这个类的这个成员。 4． 背景知识介绍：对类成员的访问权限由3个方面决定：（1）类的访问权限（public或default），（2）成员变量的访问权限（public, protected, default或private），以及环境与类的相互关系（同类SameClass，同包不同类SamePackageNoteSameClass，不同包但为子类OtherPackageSubClass，不同包非子类OtherPackageNotSubClass）。例如，如果一个类A是public的，它的一个成员变量x是protected的，则这个成员变量的访问权限是default的，试图访问这个类的一个运行环境与A的关系是OtherPackageSubClass，则这个环境中能够访问变量x。(Implement a program, the relationship between the classes of permissions, user input member permissions, as well as the environment of use of such objects of this class, it is judged in this environment can not access this members of this class. 4. Background knowledge: the access rights of the class members decided by three aspects: (1) access rights (public or default), (2) the member variable access rights (public, protected, default or private), as well as environmental and the relationship of the class (of similar SameClass, same package different classes SamePackageNoteSameClass, different packages, but for subclass OtherPackageSubClass, different package non-subclass OtherPackageNotSubClass). For example, if a class A is public, it s a member variable x is protected, the access rights of the member variables is default, tries to access a runtime environment for this class A relationship is OtherPackageSubClass this environment be able to access the variable x.)

加权LeaderRank算法属于基于随机游走的节点重要性排序算法，它是对LeaderRank算法的改进和加强，可以准确而迅速的对网络中的节点进行重要性排序，对错误数据有很强的抗干扰能力，输入文件时一个两列数据的txt文件，每一个数据表示一个节点的id号，这两列数据表示整个网络节点之间的指向关系，输出数据为两列数据，第一列是节点的id号，第二列是节点对应的加权LeaderRank值。

该压缩包里面包含了， java核心编程一书中的所有源代码，用户只要解压就可以运行-The package which contains a compressed, java core programming book of all the source code, users can run as long as the decompression

聚类系数是网络的重要特征，这个源代码主要是计算聚类系数。-Clustering coefficient is an important feature of the network, the source code clustering coefficient is calculated.
