when passing data fragment why - (i.e. way supposed it)

private string mparam1; private string mparam2;    public static reviewpagesfragment newinstance(string param1, string param2) {     reviewpagesfragment fragment = new reviewpagesfragment();     bundle args = new bundle();     args.putstring(arg_param1, param1);     args.putstring(arg_param2, param2);     fragment.setarguments(args);     return fragment; }  @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     if (getarguments() != null) {         mparam1 = getarguments().getstring(arg_param1);         mparam2 = getarguments().getstring(arg_param2);     } } 

instead of doing

private string mparam1; private string mparam2;    public static reviewpagesfragment newinstance(string param1, string param2) {     reviewpagesfragment fragment = new reviewpagesfragment();     fragment.mparam1 = param1;     fragment.mparam2 = param2;     return fragment; } 

the second way simpler , gives better performance. fan of k.i.s.s. question - why first way recommended way , benefit come doing way?

using bundle allows fragment persist state if it's recreated. here's more thorough explaination: best practice instantiating new android fragment
