// option 1: print in string - preferred public void testa(arraylist<string> list) {     for(string str : list) testa(str); }  public void testa(string s) {     system.out.println(s); }    // option2: print in list - not preferred public void testa(arraylist<string> list) {     for(string str : list) system.out.println(str); }  public void testa(string s) {     arraylist<string> list = new arraylist<string>();     list.add(s);     testa(list); }
