after getting json data need randomize it. brother please, have tried nothing working in advance

after queslist = quesobj.getjsonarray("questions"); // right place shuffle peterola,add randomize questions list:

    list<jsonobject> questionslist = new arraylist<jsonobject>(queslist.length());     for(int i=0,size=queslist.length();i<size;++i){         try {             questionslist.add(queslist.getjsonobject(i));         } catch (jsonexception e) {             e.printstacktrace();         }     }     long seed = system.nanotime();     collections.shuffle(questionslist, new random(seed));
