List和Array相互转换

 1         List<String> list = new ArrayList<String>();
 2         list.add("1");
 3         list.add("2");
 4         list.add("3");
 5 
 6         String[] arTmp = (String[]) list.toArray(new String[list.size() - 1]);
 7 
 8         System.out.println(arTmp.toString());
 9 
10         arTmp[2] = "99";
11         // 数组 转 List
12         List<String> list1 = Arrays.asList(arTmp);
13         System.out.println(list1.toString());
