hey all,
if i have the following code:
Comparable name = new Client("", "Molly");
String getName;
how is it possible to extract "Molly" from Comparable name and assign it to String getName?
when i print out name i get
System.out.println(name);
Molly, ,
thanx heather

You'd have to cast it to a Client.
Client client = (Client)name;
Can I ask why you're declaring it as a Comparable in the first place, rather than as a Client? If Client implements comparable, you can use it wherever a Comparable is required--it needn't be declared as Comparable.
simple answer: No, its not possible since Comparable has no method for it
a bit less simpler answer:
if you know (more or less) that it is a Client you can do something like that
if (name instanceof Client) {
Client tmp = (Client) name;
getName = tmp.getName(); // assuming Client has a getName method
}
a bit more complex:
define a ComparableWithName interface, use that instead of just Comparable and let Client implement this one.
interface ComparableWithName extends Comparable {
public String getName();
}
--
ComparableWithName name = new Client("", "Molly");
String getName = name.getName();
