@FunctionalInterface
interface Interface1 {
    public void print();
}

public class LambdaTest {
    public static void main(String[] args) {
//        Interface1 i = new Interface1() {
//            @Override

        Interface1 i = () -> System.out.println(" I am lambda Demo");

        i.print();
