String数组转List，List转String数组

List 转换为 String数组

List<String> list = new ArrayList<String>();    list.add("a1");    list.add("a2");    String[] toBeStored = list.toArray(new String[list.size()]);    for(String s : toBeStored) {         System.out.println(s);    } 

String 数组转换为 List

<span style="font-size:18px;">    String[] arr = new String[] {"1", "2"};      List list = Arrays.asList(arr);  </span>
