list和array的排序(字典排序)

		List<String> list = new ArrayList<String>();
		list.add("a");
		list.add("c");
		list.add("b");
		Collections.sort(list);
		for (String a : list) {
			System.out.println(a);
		}
		String[] a = new String[]{"c","b","a"};
		Arrays.sort(a);
		for (int i = 0; i < a.length; i++) {
			System.out.println(a[i]);
		}
