sentence compilation does not pass Final New StringBuffer ("111"); a.append ("222"); // compiled byAs you can see, final is valid only for the reference "value" (that is, the memory address), which forces the reference to point only to the object that was initially pointed to, and changes its point to cause a compile-time error. Final is not responsible for the change in the object it points to.Summarize　　A reference to the local variable data and objects (String, array, object, and so on) that

With the continuous development of the network, the current network environment has been somewhat unable to adapt to technological advances, especially in the enterprise network, Enterprise Directors and IT managers hope that their networks can be secure and easy to use, however, different network segments cannot work together.

Note: The basic idea of this paper comes from the thesis, introduces a kind of method similar to Sdn OpenFlow, and applies it to the FCoE network. This method of control flow can coexist with the SDN flow control method OpenFlow protocol, but it is not exactly the same as the data plane and control plane extending the OpenFlow protocol:)Problemintegration of storage networks into virtual networksBecause dat
