原创 失败者的必备素质

    想要做成一些事,首先要分析一下为什么事情会做不成。现在成功哲学的书太多,我们看成功者的必备素质已经看到麻木,换个思路,或许会豁然开朗。    失败者必备素质之1,不知道自己想要什么。想想看,不知道想要什么,自然不知道想做什么,不知道想做什么,自然不知道努力去做,其必然结果,在迷茫中失败,失败的最彻底。    失败者必备素质之1.5,想要的太多。有句俗语---贪多嚼不烂。对技术人员最

原创 ARP 地址解析的实现过程

以太网上的两台主机需要通信时,双方必须知道对方的MAC 地址。每台主机都要维护IP 地址到MAC 地址的转换表,称为ARP 映射表。ARP 映射表中存放着最近用到的一系列与本主机通信的其他主机的IP 地址和MAC 地址的映射。在主机启动时,ARP 映射表为空;当一条动态ARP 映射表项规定时间没有使用时,主机将其从ARP 映射表中删除掉,以便节省内存空间和ARP 映射表的查找时间。假设主机A 和主

原创 刨根问底文件结尾

        今天做管道过滤器的试验,多个过滤器是多线程并行执行的,每个线程执行结束的条件是从前一个管道的read()方法返回-1,管道就是PipedReader,其read()返回-1的条件是读到文件流末尾。        下面我就刨根问底,看看究竟什么是文件流末尾。首先打开java开发包中的源代码,找到PipedReader类,找到其中的read()方法,其中有这么一段代码

原创 java中数字字符串排序

        老师布置的一个作业要用到把文件中的各条记录按照记录中的一个字段排序,这个字段是数字字符串。本打算把字符串转成数字,再用学过的一些排序算法实现,可一想,如此强大的java,这种小小功能应该不用这么复杂的自己折腾。仔细读过书后,发现果真有捷径可走。        我的思路是这样的        1.把字符串读入ArrayList,每个字符串是一项;        2.把Ar
