4. - 函数式编程

4.1. PredicateTools

PredicateTools 用于 Predicate 的相关操作。

4.2. Functional interfaces

补充可能用得上的函数式接口：

Group	FunctionalInterface	method
UnaryOperator	BoolUnaryOperator	boolean applyAsBool (boolean)
UnaryOperator	CharUnaryOperator	char applyAsChar(char)
Throwing	Executable	void execute() throws E
Throwing	ThrowingConsumer	void accept(T) throws E
Throwing	ThrowingFunction	R apply(T) throws E
Throwing	ThrowingPredicate	boolean test(T) throws E
Throwing	ThrowingSupplier	T get() throws E
Optional	OptionalSupplier	Optional get() throws E
Optional	ToOptionalBiFunction	Optional apply(T,U)
Optional	ToOptionalFunction	Optional apply(T)
