This leads to an obvious potential DoS attack. Incoming SYN packets will be allocated too many TCB and the host's kernel memory will be exhausted. In order to avoid this memory depletion, the operating system usually associates a "backlog" queue parameter with the listening interface, which maintains both the upper TCB number of connections and the SYN-RECEIVED state. Although this scheme protects the host's available memory from attack, the backlog queue itself brings a (small) source of attack. When there is no space in the backlog, it is impossible to respond to new connection requests unless the TCB can be recycled or removed from the SYN-RECIEVE state.

D > B enters the synchronized block, and since instance is not null at this time, it immediately leaves the synchronized block and returns the result to the program calling the method. E > At this point, thread B intends to use the Singleton instance, only to find that it has not been initialized, so an error occurs. Therefore, there is still the possibility of errors in the program. In fact, the running process of the program is very complicated. From this, we can see that it is more difficult and challenging to write programs especially in multi-threaded environment. We further optimized the program:

In addition, they apply different stages of design, and the appearance mode is used in the early stage of design, because the system needs to rely on appearance in the early stage, while the adapter is applied after the design is completed. When it is found that the designed classes cannot work together, the adapter mode can be adopted. However, in many cases, the use of adapter mode should be considered at the early stage of design, such as involving a large number of third-party application interfaces. Proxy mode is that after the mode is completed, it wants to be provided to other clients in the form of services for calling. At this time, other clients can use proxy mode to access the module.
