Java, however, does not provide for pointers (direct memory addresses) to methods. Instead, interfaces are used for callbacks. In this case, a method holds an interface reference in its argument list and then invokes a method in the interface. (TheMethodclass in theReflectionpackage can represe...
INTERFACES AND INNER CLASSES ▼INTERFACES ▼OBJECT CLONING ▼INTERFACES AND CALLBACKS ▼INNER CLASSES ▼PROXIES You have now seen all the basic tools for object-oriented programming in Java. This chapter shows you several advanced techniques that are commonly used. Despite their less obvious nature, ...
What you have just seen is a simple form of lambda expressions in Java: parameters, the->arrow, and an expression. If the code carries out a computation that doesn’t fit in a single expression, write it exactly like you would have written a method: enclosed in{}and with explicitreturns...

Rather than implementing interfaces or callbacks, you'll simply annotate your plain old Java class. 不需要实现这些接口和回调,只需要注释无格式的旧Java类即可。 www.ibm.com 4. This step addresses the COM aspects of implementing interfaces, other than those in the base classes. 该步骤强调实现接口的...
