I supose by
"QName(String lname, String namespace = String())"
you mean something like
class QName{
private String namespaceURI;
private String localName;
public QName(String ln){
this.localName = ln;
namespaceURI = new String();
}
}
This si indeed a possibility, but in many cases you might need more, like, for instance, to actually pass a namespaceURI to a constructor, or even a prefix. So you can overload the constructor. Like this:
class QName{
private String namespaceURI;
private String localName;
private String prefix;
public QName(String ln){
this.localName = ln;
namespaceURI = new String();
prefix = new String();
}
public QName(String ln, String nu){
this.localName = ln;
namespaceURI = nu;
prefix = new String();
}
public QName(String ln, String nu, String px){
.....
}
}
This way the experienced users can use what suits them best.
You can also take a look at this:
http://java.sun.com/j2se/1.5.0/docs/api/javax/xml/namespace/QName.html
Chances are you have already a QName class at your disposal and you don't have to design any constructors.

How is that different from:
QName(String lname, String namespace = String())
except for the order of the arguments?
Cheers,
