String和list的转换

String org = abcd/cdas/dfdf/ffff;
//"/"可以为任何字符
List<String> orgList = Arrays.aList(org.split("/"));
orgList = [abcd,cdas,dfdf,ffff]

2、String转换long的数组

String longs = "11,22,33";
List<Long> longList =Arrays.stream(longs .split(",")).map(s->Long.parseLong(s.trim())).collect(Collectors.toList())
longList = {11,22,32}

List<String> longList = Arrays.asList(longs .split(","));
List<String> longList ={"11","22","33"}
