 Sample 1. Get all Permutations of List Elements using Apache Commons PermutationIterator

List<String> list = new ArrayList();
list.add("Washington");
list.add("Nevada");
list.add("California");

PermutationIterator permIterator = new PermutationIterator((Collection) list);
      
permIterator.forEachRemaining(System.out::print); // prints [Washington, Nevada, California][Washington, California, Nevada][California, Washington, Nevada][California, Nevada, Washington][Nevada, California, Washington][Nevada, Washington, California]
