Lambda表达式初体验(一)

public interface Orderservice {
    void get();
}

public class Test02 {
    public static void main(String[] args) {
        new Orderservice() {
            @Override
            public void get() {

            }
        }.get();
    }
}

public class Test02 {
    public static void main(String[] args) {
        ((Orderservice) () -> {

        }).get();
    }
}
