in java by using Math.random() function you can do it. here i give you a example with a string array . you can use this logic in you problem also.. String[] name={ABCDE}; Set track=new HashSet (); for(int i=0;i =0 && num<5 && (!track.contains(num))) { track.add(num); System.out.println(name[num]); i++; } }
