} 

class EchoService implements Service{ 

private String id; 

public void initialize(String id){ 

 this.id = id; 

} 

public String processRequest(String request){ 

 String response = ECHO:  + request; 

 return response; 

}  

} 

abstract class ServiceImpl implements Service{ 

private String id; 

public void initialize(String id){ 

 this.id = id; 

} 

} 

class CapitalizeService extends ServiceImpl{ 

public String processRequest(String request){ 

 return request.toUpperCase(); 

}
