Java: interfaces and abstract classes

[pinansonoyon]

Hello everybody!
I use the actiWATE library for one project. This is a code
file Main.java

import bro.bro;
import java.io.IOException;
import java.io.UnsupportedEncodingException;

public class Main
{
public static void main(String[] args) throws UnsupportedEncodingException, IOException
{
bro doBro= new bro();
}
}

file bro.java

import com.actimind.actiwate.http.HttpResponse;
import com.actimind.actiwate.testing.ActiwateTestCase;
import java.io.IOException;
import java.io.UnsupportedEncodingException;

public class bro extends ActiwateTestCase {
public bro() throws UnsupportedEncodingException, IOException{
disableJavaScript(true);
goTo( "http://google.com" );
}
}

And now I want to get all headers. In this library is a method getAllHeaders() and I hoped use it like this

file bro.java

package bro;
import com.actimind.actiwate.http.HttpResponse;
import com.actimind.actiwate.testing.ActiwateTestCase;
import java.io.IOException;
import java.io.UnsupportedEncodingException;

public class bro extends ActiwateTestCase {
public bro() throws UnsupportedEncodingException, IOException{
       disableJavaScript(true);
       goTo( "http://google.com" );
}
public class WOW implements HttpResponse 
{
}
}

but NetBeans IDE 6.8 required implementing all abstract methods. It's great but the next step is the overriding all these methods but I don't want it. I want use method getAllHeaders() without any overriding because it returns all header in one string.
Ok. In order to don't overriding method I do it like an abstract class WOW with implements HttpResponse

package bro;
import com.actimind.actiwate.http.HttpResponse;
import com.actimind.actiwate.testing.ActiwateTestCase;
import java.io.IOException;
import java.io.UnsupportedEncodingException;

public class bro extends ActiwateTestCase {
public bro() throws UnsupportedEncodingException, IOException{
       disableJavaScript(true);
       goTo( "http://google.com" );
}
public abstract class WOW implements HttpResponse 
{
}
}

The creation of objects from abstract classes is impossible and we need to create a class that extends abstract class WOW like this

package bro;
import com.actimind.actiwate.http.HttpResponse;
import com.actimind.actiwate.testing.ActiwateTestCase;
import java.io.IOException;
import java.io.UnsupportedEncodingException;

public class bro extends ActiwateTestCase {
public bro() throws UnsupportedEncodingException, IOException{
       disableJavaScript(true);
       goTo( "http://google.com" );
}
public abstract class WOW implements HttpResponse
{
}
public class WOW2 extends WOW
{
}
}

But in this case IDE requires the implementation of all abstract methods with them overriding again! How can I avoid it and use this method? Thanks for all answers!

If you extend an abstract class you have to either

A) implement its method
B) declare your class abstract as well
