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...
interfaces can also define constants. What is more important, however, is what interfacescannotsupply. Interfaces never have instance fields. Before Java SE 8, methods were never implemented in interfaces. (As you will see in Section 6.1.4, “Static Methods,” on p. 298...
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, ...
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...
