ArrayList<Integer> list = new ArrayList<Integer>();
list.add(12);
list.add(23);
list.add(-5);
list.add(-5);
list.add(12);
Collections.sort(list);
for (Integer theNextInt : list)
System.out.print(theNextInt + " ");
System.out.println("=================");
System.out.println(list.contains(-5));
System.out.println(list.contains(9999));
System.out.println(Collection.min());
System.out.println(Collections.binarySearch(list, 23));
System.out.println("=================");
Collections.reverse(list);
for (Integer theNextInt : list)
System.out.print(theNextInt + " ");
