Would someone provide an example where Foo extends Bar and there are private fields in Bar which Foo uses in its constructor(s)? Seems a conundrum...Using the following example:

Without reflection there is no way, but given your example
you just need to call setName(name) to achieve your intention.


Even with reflection, is it possible? I was just playing around with reflection and I noticed that the API only promises to return public methods and fields. Maybe there's a sneaky "getAll" that I missed...

Anyway, calling super here is probably the best choice. Note than in your example you must call super because Bar has no default constructor.

One can also provide a factory method such as newInstance below.

package attribs;

public class Foo extends Bar {
private String id;
public Foo(String name,String id){
super( name ); // New line here
//this.name = name; // Get rid of this one
this.id = id
}
static public Foo newInstance( String id ) {
Foo f = new Foo( "default", id );
f.setSomeOtherNonfinalProperty( "non" );
return f;
}

package attribs;

public class Bar {

private String name;

public setName(String name) {this.name = name;}
}

.
