问Java Cucumber -步骤定义实现En接口-可能在java 11？

EN

import static utils.BasePage.driver;
import io.cucumber.java.af.En;

public class LandingPageStepDefs implements En {
    
    @Override
    public String value() {
        return null;
    }
    
    @Override
    public Class<? extends Annotation> annotationType() {
        return null;
    }
    
    LandingPage landingPage = new LandingPage(driver);

    public LandingPageStepDefs() {
    
        Given("^Customer is on landing page$", () -> {
            landingPage.verifyTextOnBanner();
        });   
    }
}
