Question

I have the following Set in Java:

Set< Set<String> > SetTemp = new HashSet< Set<String> >();

and I want to move its data to an ArrayList:

ArrayList< ArrayList< String > > List = new ArrayList< ArrayList< String > >);

Is it possible to do that ?

Answer 1

You simply need to loop:

Set<Set<String>> setTemp = new HashSet<Set<String>> ();
List<List<String>> list = new ArrayList<List<String>> ();
for (Set<String> subset : setTemp) {
    list.add(new ArrayList<String> (subset));
}

Note: you should start variable names in small caps to follow Java conventions.
