What is functional interface (S.A.M.)?
A functional interface is an interface that contains only one abstract method (Single Abstract Method)
A functional interface can have any number of default and static methods
@FunctionalInterface annotation is used to ensure an interface can’t have more than one abstract method
What is built-in function interface?
Java 8 provides several in-built functional interfaces that can be used when creating lambda expressions or method references.
Predicate / boolean-valued function
The Predicate interface has an abstract method test which gives a Boolean value as a result for the specified argument
Function
The Function interface has an abstract method apply which takes argument of type T and returns a result of type R.
What is Consumer
The Consumer interface has only one single method called accept(). It accepts a single argument of any data type and does not return any result.
What is Supplier
A Supplier interface has only one single method called get(). It does not accept any arguments and returns an object of any data type.
What is UnaryOperator Interface ?
What is Predicate Joining ?
Join multiple predicates and apply on same input data
1. Predicate.and() – Logical AND
When evaluating the composed predicate, if first predicate is false, then the other predicate is not evaluated.
2. Predicate.or() – Logical OR
When evaluating the composed predicate, if first predicate is true, then the other predicate is not evaluated.
