array containing the same list of interfaces (in the order specified at its creation), invokinggetMethodson itsClassobject will return an array ofMethodobjects that include all of the methods in those interfaces, and invokinggetMethodwill find methods in the proxy interfaces as would be expected....
It returns a list of Future objects, which all represent the “future” result of the computation. If we were to work in an asynchronous fashion, we could test each Future object to check whether its corresponding Callable has finished its work and check whether it threw an exception, and ...
Laziness-seeking. Many stream operations, such as filtering, mapping, or duplicate removal, can be implemented lazily, exposing opportunities for optimization. For example, "find the firstStringwith three consecutive vowels" need not examine all the input strings. Stream operations are divided into in...
line all characters following the first comment character are ignored. If a service provider class name is listed more than once in a provider-configuration file then the duplicate is ignored. If a service provider class is named in more than one configuration file then the duplicate is ignored...

第一阶段:主要是解析调用的参数,即argv[],通过for循环遍历解析,通过string的方法来判断,主要出是初始化startSystemServer、abiList和socketName变量 第二阶段:调用registerZygoteSocket(socketName)方法注册Zygote的socket监听接口,用来启动应用程序的消息 第三阶段:调用preload()方法装载系统资源,包括系统预加载类、Framework...
