将Runnable实现为接口的抽象类

Question

如何将实现Runnable的抽象类重构为接口？

sudo yum install postgresql93-devel

更新：以及如何在将来删除通用通配符类型的使用？

import com.codahale.metrics.health.HealthCheck;

public abstract class ApplicationProcessor implements Runnable {

    public abstract HealthCheck getHealthCheck();
}

由于

Answer 1

public interface ApplicationProcessor extends Runnable {
    // interface methods are by default public and abstract
    HealthCheck getHealthCheck();
}

第2部分使用

Future<Void> or just Future
