I have a series of classes in my java program as follows:
src
|
|- BaseCost
|- com.jdoe.nationalcosts
|- EntryTicketCost
|- FlightCost
|- com.jdoe.internationalcosts
|- HotelCost
I'm trying to use BaseCost
as and abrstract class that extends EntryTicketCost
,FlightCost
and HotelCost
. However, my IDE says that it cannot resolve EntryTicketCost extends BaseCost
. Am I organizing the files in the right way? If not, how am I supposed to order them for the inheritance to work?
If it helps, this is the shortened code for BaseCost
import sun.reflect.generics.reflectiveObjects.NotImplementedException;
import java.util.Arrays;
import java.util.List;
public abstract class BaseCost {
private String id;
private String name;
private String description;
private String costType;
private int holder;
public String getId() {...}
public void setId(String id) {...}
public String getName() {...}
public void setName(String name) {...}
public String getDescription() {...}
public void setDescription(String description) {...}
public String getCostType() {...}
public void setCostType(String costType) {...}
public int getHolder() {...}
public void setHolder(int holder) {...}
public CalcValue getCalculated(int guides, int passengers){...}
public void removeFromString(String string){...}
BaseCost is not in any package (basically in default package) hence you can not import it. Solution: Keep BaseCost in some package and import in EntryTicketCost as well as other classes where ever you are extending.
Hope this help.
