Reset arraylist object property for all objects

Question

I'm having an arraylist which contains object of class X. Class x has property name & desc. When I pass this object to a method, it needs to set all class object(X) description as 'MyDescription'. What is the best way to do it.

For eg

class X{
    String name;
    String desc="Hello";
    //We have getters & setters too.
}

ArrayList<X> obj=getArraylist();

Now we got say 10 object of class X in obj. I need to reset all its description to 'MyDescription'

Can I do without looping into each object and reset its value? Please suggest.

No, you cannot accomplish that without iterating over the list. — Bhesh Gurung, Jun 13 '13 at 18:24
I need more thoughts,
As string is immutable, can we do something. — MukeshKoshyM, Jun 13 '13 at 18:27
How would you expect to be able to do this without iterating over the list? — Peter Mularien, Jun 13 '13 at 18:40

No, you can't do this without looping of some form.

The best way to accomplish this is to iterate of the list and set the values as needed.

If we use something else than arraylist, Can we do this. Trying to avoid iteration. – MukeshKoshyM Jun 13 '13 at 18:30

The very idea of performing an action on each object is iteration. What could you possibly be looking for? – sleeparrow Jun 13 '13 at 18:40

Why are you so against iteration? It is a basic fundamental of programming. There is a reason it exists and so many people use it. – BlackHatSamurai Jun 13 '13 at 18:41
