Moving data from a HashSet to ArrayList in Java

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

Moving Data HashSet to ArrayList

Set<String> userAllSet = new HashSet<String>(usrAllTemp); List<String> usrAll = new ArrayList<String>(userAllSet); 

Here usrAllTemp is an ArrayList, which has some values. Same Way usrAll(ArrayList) getting values from userAllSet(HashSet).

Answer 2

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.
