PAGE 基于JAVA的多线程下载工具的实现 摘 要 随着现代科技的迅猛发展，以信息化为基础的计算机技术已成为全球信息通信的雏形，计算机的发展逐渐进入一个全新的发展阶段，成为人们现在众所周知的热门话题。 计算机技术的发展，使得网络成为人们获取信息的重要途径之一。人们获取数据，进行通信的方式其实就是将数据从一方传送到另一方。但是在传送的过程中，通常会由于一些突发状况，如网络接触不良导致掉线、电脑死机、蓝屏、或者电脑的一些其他原因，使得数据传输失败。尤其适当用户看到已经传到快要完成的时候，突然中断，导致其不得不重新下载，这给用户带来了很大的不便。多线程下载可以实现多个任务同步下载，大大的提高了下在速度，为用户节省了时间。因此，研究JAVA多线程下载对人们方便使用下载工具下载内容具有重要意义的。 关键字：JAVA；多线程下载；数据传输 Based on the Realization of the Java Multi-thread Download Tools Abstract With the rapid development of modern science and technology, represented by the Internet also obtains the rapid development of computer network. Therefore, prompting the development of computer has entered a new stage, which become a hot topic that is known to all and everyone has concerned. The development of computer technology makes the network become one of the most important ways of accessing to information. To get the data, the way people communicate is to transfer data from one party to another party. But in the process of transfer, usually due to some unexpected situation, such as network poor contact lead t o drop, computer crashes, blue screen, or some other reasons, the computer makes a failure in data transmission. Particularly appropriate users have seen it almost finished, s suddenly break, it has to download again, which gives the user a great deal of inconvenience. Multi-threaded download can implement multiple task synchronous download, greatly improves the speed, which saves time for the users. Therefore, be convenient for people to study JAVA multi-thread download in using download tools to download content is of great significance. Key words: Java; Multi-threaded download; data transmission PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT 2 PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT 1 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc12199 摘 要 PAGEREF _Toc12199 I HYPERLINK \l _Toc3116 Abstract PAGEREF _Toc3116 II HYPERLINK \l _Toc27690 1 绪论 PAGEREF _Toc27690 1 HYPERLINK \l _Toc4000 1.1 课题背景 PAGEREF _Toc4
