Question about inheritance

Hi,

Please look at the following codes

Code:

---

public abstract class A implements Serializable
{
      // method
}

public class B extends A
{
      // method
}

---

Will the class B inherits the Interface "Serializable"?

Yes, inheritance obeys the 'is a' rule: a subclass is a superclass. Your superclass is a Serializable so your subclass is a Serializable.

kind regards,

Jos

Thank you.:)

You really should read the API before asking a question. In the case of Serializable, it's specifically documented.
All subtypes of a serializable class are themselves serializable.
Serializable (Java Platform SE 6)
