Question

IDsmCore.java (interface class)

public interface IDsmCore
{
    public void Initialize( String path, String fileName );
    public void Uninitialize( );
}

IDsmToken.java (interface class)

public interface IDsmToken
{
    public String GetID( );
    public void SetID( String id );
}

DsmCore.java (interface implementation)

public class DsmCore implements IDsmCore
{
    @Override
    public void Initialize( String path, String fileName ) {
        // Some code goes here.
    }

    @Override
    public void Uninitialize( ) {
        // Some code goes here.
    }

    public class DsmToken implements IDsmToken
    {
        @Override
        public String GetID( ) {
            // Some code goes here.
        }

        @Override
        public void SetID( String id ) {
            // Some code goes here.
        }
    }
}

How you can see DsmToken class is in the DsmCore class. Now I want to extends DsmToken class, for example I can extends DsmCore in this way:

public class MyExtendedDsmCore extends DsmCore
{


}

And how I can extends DsmToken ?

Answer 1

public class MyExtendedDsmCore extends DsmCore.DsmToken {
}

and DsmToken should be static.
