Introduced in Java 8, they are the backbone of lambda expressions and the Stream API, enabling a more functional style of programming. They are also known as <strong>Single Abstract Method (SAM)</strong> interfaces.</p> <p>To ensure an interface is a functional interface, you can use the <code>@FunctionalInterface</code> annotation. The compiler will then trigger an error if the interface does not meet the requirements.</p>
