Example:

public class LambdaFun {
	@FunctionalInterface
	public static interface F {
		public String get();
	}
	public static void test(F f) {
		System.out.println(f.get());
	}
	public static void main(String[] args) {
		test(() -> "one");
		test(() -> "two");
		test(() -> "three");
		F four = () -> "four";
		test(four);
	}
}
