import java.lang.reflect.Method;

public class IsDefaultExample {
    private interface Task {
        default void asyncProcess() {}

        void process();
    }

    public static void main(String... args) throws NoSuchMethodException {
        Method m = Task.class.getDeclaredMethod("process");
        System.out.println(m.isDefault());
        Method m2 = Task.class.getDeclaredMethod("asyncProcess");
        System.out.println(m2.isDefault());
    }
