Java编写的简单的Mail发送程序，包含了邮件的发送过程，相应过程的演示。 可以被其它Serverlet调用来发送邮件。-Mail procedure ,written in Java to send a simple , contains the e-mail sending process, the corresponding demonstration of the process. Other Serverlet can be invoked to send mail.

我在做项目的时候需要将文件进行压缩和解压缩，于是就从http://www.icsharpcode.net下载了关于压缩和解压缩的源码，但是下载下来后，面对这么多的代码，一时不知如何下手。只好耐下心来，慢慢的研究，总算找到了门路。针对自己的需要改写了文件压缩和解压缩的两个类，分别为ZipClass和UnZipClass。其中碰到了不少困难，就决定写出来压缩和解压的程序后，一定把源码贴出来共享，让首次接触压缩和解压缩的朋友可以少走些弯路。-When I was doing the project will need to compress and decompress files, so downloading from http://www.icsharpcode.net on the compression and decompression of the source code, but it downloaded, and faced with so many code, 1:00 do not know how start with. Had under-resistant heart, the slow research and finally found the avenues. In light of their need to be rewritten a file compression and decompression of the two classes, namely ZipClass and UnZipClass. Which encountered many difficulties, it was decided to write out compression and decompression process, some paste out of the source code sharing, so that the first contact with compression and decompression of friends can take some less roundabout.

测试压缩一个425K的文件需要9.4秒，压缩后的文件为177K。如果要提高压缩速度，那么算法的复杂度就得增加了。 -compression testing of a 425K file 9.4 seconds, compressed the files to 177K. If we are to raise compression speed, then the algorithm complexity must increase.

这是小波变换的一个源代码，vc实现，很有用的哦，希望对大家有所帮助。-This is a wavelet transform source code, vc realized, very useful Oh, we want to help.

程序打包压缩，目录浏览，程序代码的压缩、备份-Program package compression, directory browsing, code compression, backup

LZW算法的实现，用C语言编写的，LZW算法是一个压缩算法，压缩比例很高！喜欢了解的人看看吧！-lzw algorithm implementation！

图像压缩，预测编码，给出了两种预测编码法，及其比较-Image compression, predictive coding, is given two kinds of predictive coding method, and its comparison

此源码为按照jpeg标准编写的huffman压缩程序源代码，主要是进行图像数据压缩-source of this according to jpeg standards prepared by the Huffman compression source code, mainly for image data compression

简单的五子棋功能。可实现人机对弈。可以双人对弈。操作简单方便-simple game

本源码直观演示了音频ADPCM解压压缩算法 可手动数入数据,点击压缩解压按扭即可显示压缩解压的结果!-The source of the audio visual presentation ADPCM compression algorithm can extract the data manually into the number, click the button to display the compressed compression decompression decompression results!
