✨The coolest feature in Java 8- Functional interface I've been asked this question multiple times in interviews, so I thought I'd share a clear explanation with all of you. If you have any doubts, feel free to reach out to me.

✅Actually, a normal interface can have multiple abstract methods. If we keep only one abstract method in the interface, it acts as a functional interface.
✅We can use the `@FunctionalInterface` annotation on this interface, and if we are adding multiple abstract methods, it will show an error.
✅ It is used to represent the lambda expression, which is a short block of code or method implementation without a method name.
✅You can find this example program below:
@FunctionalInterface
interface FuncInterface {
public void method();
}

class Test implements FuncInterface {
public static void main(String[] args) {
FuncInterface obj = () ➡️ {
System.out.println("implementation");
};
obj.method();
}
}
