Type Parameters: T - the type of the input to the operation All Known Subinterfaces: Stream.Builder Functional Interface: This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference. We have created a consumer implementation that consumes a String and then prints it. To avoid this kind of a scenario, ease programming & bring a common standard in usage of functional interfaces, a set of in-built functional interfaces such as Predicate, Function, Consumer & Supplier have been defined.

Notable is that for a given value of A, the function should always return a specific value of B. But the benefit of using them is not clear. So you can't look at the specification for Function (or any of the other functional interfaces, for that matter) and attempt to discern what they mean.
