I did read the errors. The problem was understanding what the errors were telling me. And the next issue is determining what I can do about it with my limited knowledge.
I am using the Joda example that was discussed before (from the Henrique Prange example).
With the information you gave me, this is what I did.
googled java class inheritance to learn what this is:
The syntax for creating a subclass is simple. At the beginning of your class declaration, use the extends keyword, followed by the name of the class to inherit from:
class MountainBike extends Bicycle {
// new fields and methods defining a mountain bike would go here
}
so what do I have in LocalTime:
/**
* LocalDate custom type.
*
* @author <a href="mailto:email@hidden";>Henrique Prange</a>
*/
public class LocalDate implements ReadablePartial, Comparable<Object>
{
}
great the example never mentions implements. so googling "java class extends implements" gives a tutorial:
class MyClass extends MySuperClass implements YourInterface {
//field, constructor, and method declarations
}
So my attempt is to add into LocalDate the extends like this:
public class LocalDate extends java.util.Date implements ReadablePartial, Comparable<Object>
{
}
but then there is an error:
- The interface Comparable cannot be implemented more than once with different arguments: Comparable<Date> and
Comparable<Object>
so I checked the docs on java.util.Date:
public class Date
extends Object
implements Serializable, Cloneable, Comparable<Date>
so he implements Comparable<Date> but LocalDate had Comparable<Object>.
I hate this stuff. So I deleted Comparable from LocalDate and now there is an error with a method:
Name clash: The method compareTo(Object) of type LocalDate has the same erasure as compareTo(T) of type Comparable<T> but does
not override it
I made the executive decision to comment out the compareTo() method in LocalDate.
And to my complete surprise, it works.
But without your help reading the error log, I didn't even have an idea where to start looking.
Of course, maybe my hacking is actually making things worse. I guess I will have to keep my fingers crossed and hope youse guys don't get too tired helping people like me.
Thank you,
Ted
