1、为何有一个线程的while不执行

数据库只有一条语句么 rs 是ReslutSet 类么， .next()会使指向下一条记录，即调用System.out.println(cons.rs.next());这条语句后，指向第一条记录； while(cons.rs.next())会指向第二条记录，如果只查出一条记录的话，就不会执行while里面的了

3、关于遍历 赋值，有个疑问

List list = new ArrayList();

4、英语翻译While troubleshooting the problem,the administrator views the output of the show vtp status command,which is displayed in the graphic.What commands must be issued on this switch to add VLAN 50 to the database

先说题目的意思：就是当你排错的时候,管理员通过show vtp status查看到了输出的信息,信息显示在了图形上面.问你使用哪个命令可以把vlan 5添加到交换机的数据库中.
这个题目很基础的.
题意呢,其实最后一句就够了,就是问你怎么添加一个vlan5,vtp状态表也没有必要看的.
