Adding Objects to Vector

Question

Hi,
I have a class that has two private variables:
private String tableName;
private Vector iffields;
The vector is supposed to be filled with objects of
another class called DIFField.
How can I write a method that adds DIFFields to this
iffields Vector in a way that they all don't refer to
the same Object??
e.g.
in my main code I do: DIFField afield = new afield("blabla","blabla");
afield.setCode("111");
afield.setSign("+");
I want to keep using that same afield (in a loop) for adding new
fields to the iffields vector. I could do this if I could set everything
in the constructor, I know that, but that's something that's not possible. (otherwise: iffields.addElement(new DIFField("blabla","blabla");)
Can anybody help me??
Regards,
Sven

How can I write a method that adds DIFFields to this
iffields Vector in a way that they all don't refer to
the same Object??The only way to do that, ie, the normal way, would be to use the new operator and contruct each object within your loop. You can still use the same variable name, no problem there.

iffields.addElement(new DIFField("blabla","blabla");)What do you mean that is impossible? Have you tried instantiating your DIFField, calling the methods, then adding it to the vector?
for( int i = 0 ; i < 5 ; i++ )
   DIFField df = DIFField( "foo", "bar" ) ;
   df.setCode( "111" ) ;
   df.setSign( "+" ) ;
   iffields.addElement( df ) ;
}
