Make an arraylist with all the individual items.

Generate a random number (not larger than the current size of the arraylist) and get then remove that index from the arraylist. Repeat.

String[] str={"a","y","z","0","1","2","3","4"};
List<String> list=new ArrayList(Arrays.asList(str));
System.out.println( Collections.shuffle(list));
