      List<String>  destlst = new ArrayList<String> (10);
      
      // populate two lists
      srclst.add("tutorial");
      srclst.add("from");
      srclst.add("java2s.com");
      
      destlst.add("Java Tutorial");
      destlst.add("from");
      destlst.add("java2s.com");      
      
      // check elements in both collections
      boolean iscommon = Collections.disjoint(srclst, destlst);
