This is well understood. In actual development, we often encounter too many methods defined in this interface, so that sometimes we do not need them all in some implementation classes. Look at the code:绿萝刚刚端起碗到了嘴边，突然身子一晃，转身干呕起来。二战时，在德国占领下的波兰，管道工波德克（罗伯特·维凯威兹 饰）与搭档扎佩克兼做着小偷的勾当，错综复杂的下水道成了他们最好的隐匿处和贮藏室。他和城市中被封锁的犹太区做生意，跟德军中的乌克兰军官是旧相识，乱世中享有一点生活的自在。不久德国人开始屠杀、搜捕犹太人，部分不想被押往集中营的犹太人和波德克达成交易，按人头计价得到了藏身下水道的机会，黑暗又臭气熏天的下水道成了波德克收留犹太人的避难所，地面上的犹太人很快被抓捕一空，在物价飞涨和德国人持续的高压下，扎佩克离他而去，波德克只靠自己艰难维系着下水道中犹太人的安全……According to the proportion method, the monthly minimum wage standard in this area is calculated as follows: monthly minimum wage standard = 210 × 1.87 + a = 393 + a (yuan) (1)④ Thread switching cost is very high. When the operating system switches threads, the context of the thread needs to be preserved and then the system call is executed. If the number of threads is too high, it will not only bring many useless context switches, but also may cause the time for thread switching to be performed to be even longer than the time for thread execution. At this time, the performance is often that the system load is too high and the utilization rate of CPU SY (system CPU) is extremely high, resulting in the system almost falling into an unavailable state.
