java编程思想，比较经典的一本书，从入门到进阶(think in java)

用JAVA写的带通滤波代码，实现思路很简单，没有采用各种数字滤波的方法。而是通过傅里叶变换到频域，将要求外的频率均置0，再逆傅里叶变换得到的。效果还不错。(Written using JAVA bandpass filtering code to achieve the idea is very simple, without using a variety of digital filtering approach. But through the Fourier transform to the frequency domain, the frequency requirements are set to 0, then the inverse Fourier transform. Results were pretty good.)

说明：  java 写的一个ftp客户端！可以运行ssh！！！(write a java ftp client! Can run ssh! ! !)

在Java中导入Excel2007或者Excel2003文档的数据(In Java import Excel2007 or Excel2003 document data)

最近分析一些JAVA程序，对JAVA的反编译进行了一番了解，下面将我所了解的情况作以下介绍，希望对JAVA爱好者有所帮助。(Recently analyzed some JAVA program, some understanding of JAVA decompile, below I understand the following introduction, I hope to help the JAVA enthusiasts.)

模拟如下图所示的动态时钟界面（指针朝向不限）。程序文件命名为Exe8_2.java。(A CＬＯＣＫ)

采用Java语言开发的，基于序单开链理论的机构结构分解程序，可以将各种分解路线和生成的对应回路完整保存(The development of the Java language, the decomposition procedure based on the institutional structure of the sequence a single open-chain theory, the various decomposition route and generate the corresponding loop intact)

This is a sample for multi thread java application. Is pretty easy for doing large data processing

仓库管理系统，JAVA语言+SQL数据库 (Warehouse management system, JAVA+ SQL database language)
