You could use the standard JUnit annotations.

In your runner class write something similar to this:

@RunWith(Cucumber.class)
@Cucumber.Options(format = {"html:target/cucumber-html-report", "json-pretty:target/cucumber-json-report.json"})
public class RunCukesTest {

    @BeforeClass
    public static void setup() {
        System.out.println("Ran the before");
    }

    @AfterClass
    public static void teardown() {
        System.out.println("Ran the after");
    }
}

What you could do is to register event handler for TestRunFinished event. For that you can create a custom plugin which will register your hook for this event :

public class TestEventHandlerPlugin implements ConcurrentEventListener {

    @Override
    public void setEventPublisher(EventPublisher eventPublisher) {
        eventPublisher.registerHandlerFor(TestRunFinished.class, teardown);
    }

    private EventHandler<TestRunFinished> teardown = event -> {
        //run code after all tests
    };
}

and then you will have to register the plugin :

• if you are running cucumber CLI you can use -p/--plugin option and pass fully qualified name of the java class : your.package.TestEventHandlerPlugin
• for Junit runner :

@RunWith(Cucumber.class)
@CucumberOptions(plugin = "your.package.TestEventHandlerPlugin") //set features/glue as you need.
public class TestRunner {

}

With TestNG suite annotations would work as well.

@BeforeSuite
public static void setup() {
    System.out.println("Ran once the before all the tests");
}

@AfterSuite
public static void cleanup() {
    System.out.println("Ran once the after all the tests");
}
