代碼說明:由於你提供的Main裡面只有兩個地方可以 // expand here ............. 只好寫了一個比較笨的,只在這兩個地方加代碼,但用到了java.io.*和java.util.*,因為你Main裡面已經import了,所以應該不算違規。。。。另外兩個類不在 //expand那裡,是因為你要求要自訂class的 import java.io.*; import java.util.*; /** * Exercise 29 * */ public

大學生: 代碼運行過了,很好,完全滿足要求啦。 不過還有一點小問題~~就是Hashtable 沒學過,而且今天老師上課講了下說可以用Vector實現。 能不能再改下代碼呢?恩還有一點,就是英語文法問題了1. networks – list all networks connected to aparticular node 是指列出一點讓然後顯示所有聯絡的網路,貌似你和2剛好寫反了,不過這個不用改了,我自己能改,只是順便說一下~~ 還有一點小問題~~

上次裝了CentOS之後,利用SecureCRT 登入之後發現 Telent登入不上,但是用SSH可以登入上。在windows cmd telnet又可以telnet上。一直不知道原因,google了一把找到辦法,但是不明白原理,還得以後繼續學習Linux的時候 學懂原理,解放的辦法如下:方法一:修改/etc/hosts,在該檔案添加新行,輸入你的IP地址和機器名,儲存以後,再次串連即可。方法二:修改服務端的/etc/nsswitch.conf 檔案,把hosts: files
