Java: Interfaces
Answer
They allow lambda expressions and functional programming.
Functional interfaces have a single abstract method and are used extensively in lambda expressions, introduced in Java 8. This facilitates functional programming styles in Java. For example, the 'Runnable' interface is a functional interface, enabling you to write concise and efficient code using lambdas, such as replacing `new Runnable()` with simpler lambda syntax.
