2. creation of objects
You need to use the new operator when creating an object. The new operator can allocate and initialize memory for an instance of any specified type. The syntax for creating an object is as follows:Object name = new class name ();You need to be aware of when creating objects:(1) The class name of the class to which the object i
substitutionIn the above question, we use the equivalent substitution to solve will be more easy to understand, for example: a=1,b=2 want to have a and B assigned value Exchange, need to take an intermediate value C, they can be switched to achieve. Similarly, in order to sort the problem, we can use this method, according to from the big to the small or from the smallest to the big order.A=1;b=2;Median value c=0;C=a; A=b; B=c, you can exchange values for a and B.Third, the statement---the fore
Ifconfig [Interface]Ifconfig interface [Aftype] options | Address ...Ifconfig is a tool for viewing and configuring network interfaces. Ifconfig configuration information is restored after the network device restarts. To permanently save, go to configuration file configuration.Address can be inet (TCP/IP, default IPv4), Inet6 (IPV6), ax25 (AMPR packet radio), DDP (Appletalk Phase 2), IPX (Nocell IPX), Netrom (AMPR Packet radio)Note: CetOS6.8 prompts that this command is obsolete, use the IP comm
IPv6 test to test the use of the new network established by VMware. We recommend that you open tcpdump-6 on the other console interfaces of the virtual machine to observe the IPv6 protocol.
1) IPv6 test preparation:When installing the system, iproute and iputils are both tools that can test IPv6. In other Linux versions, IPv6 support modules are not loaded by default. Load each tool.
R1:~# modprobe ipv6 lsmod |grep ipv6
If the IPv6 module is successfully loaded, perform the fol

Whether it is in the actual production of the bad, or in peacetime practice, a network card set up multiple IP addresses is very common, but also very useful.We set multiple IP addresses on a network card with the centos6.8 system as a column.1>.
