細(xì)菌實(shí)驗(yàn)分組 有一種細(xì)菌分為A、B兩個(gè)亞種，它們的外在特征幾乎完全相同，僅僅在繁殖能力上有顯著差別，A亞種繁殖能力非常強(qiáng)，B亞種的繁 殖能力很弱。在一次為時(shí)一個(gè)小時(shí)的細(xì)菌繁殖實(shí)驗(yàn)中，實(shí)驗(yàn)員由于疏忽把細(xì)菌培養(yǎng)皿搞亂了，請(qǐng)你編寫一個(gè)程序，根據(jù)實(shí)驗(yàn)結(jié)果，把 兩個(gè)亞種的培養(yǎng)皿重新分成兩組。

All of Java s Input/Output (I/O) facilities are based on streams, which provide simple ways to read and write data of different types. Java provides many different kinds of streams, each with its own application. The universe of streams is divided into four large categories: input streams and output streams, for reading and writing binary data and readers and writers, for reading and writing textual (character) data. You re almost certainly familiar with the basic kinds of streams--but did you know that there s a CipherInputStream for reading encrypted data? And a ZipOutputStream for automatically compressing data? Do you know how to use buffered streams effectively to make your I/O operations more efficient? Java I/O, 2nd Edition has been updated for Java 5.0 APIs and tells you all you ever need to know about streams--and probably more.

What I am trying to introduce here is a full fledged Java Instant messenger, which has all the features supplied by commercial messengers like Yahoo or MSN. Although it cannot compared to be in par with those messengers, it is an attempt by me to learn Advanced Java and JNI concepts. The challenges I faced here were often overcome by referring to numerous sites, which nearly zeroes in or completely solved the issues I faced at that point of time. It improved my learning curve and also believe would do the same to you too. Ofcourse, there are some bugs and glitches, which I hope you would excuse. Thanks to anyone who takes the pain to report them or even suggest better way of doing things to me.

Java technology is both a programming language and a platform. The Java programming language originated as part of a research project to develop advanced software for a wide variety of network devices and embedded systems. The goal was to develop a small, reliable, portable, distributed, real-time operating platform. When the project started, C++ was the language of choice. But over time the difficulties encountered with C++ grew to the point where the problems could best be addressed by creating an entirely new language platform. Design and architecture decisions drew from a variety of languages such as Eiffel, SmallTalk, Objective C, and Cedar/Mesa. The result is a language platform that has proven ideal for developing secure, distributed, network-based end-user applications in environments ranging from network-embedded devices to the World-Wide Web and the desktop
