Primitive Type Specializations of Function – Functional-Style Programming

Primitive Type Specializations of Function<T, R> As can be seen in Table 13.7, there are three categories of primitive type one-arity specializations of the Function<T, R> interface, each distinguished by a naming scheme. Also, these primitive type one-arity specializations do not define any default methods. These one-arity generic functions have the functional method apply: primitive … Read morePrimitive Type Specializations of Function – Functional-Style Programming

Suppliers – Functional-Style Programming

13.5 Suppliers As the name suggests, the Supplier<T> functional interface represents a supplier of values. From Table 13.4, we see that its functional method get() has the type () -> T—that is, it takes no argument and returns a value of type T. Table 13.4 shows all supplier functional interfaces provided in the java.util.function package. … Read moreSuppliers – Functional-Style Programming
