Java String和List互轉

List<String> list = new ArrayList<>();
for (int i = 0; i < 10; i++) {
    list.add(System.currentTimeMillis() + RandomStr.getSixNum());
}
String symbol = StringUtils.join(list.toArray(), ",");
System.out.println(symbol);

List<String> lis = Arrays.asList(symbol.split(","));
System.out.println(lis);
for (String s : lis) {
    System.out.println(s);
}
