Kotlin 特殊字符处理

1、kotlin 版本

fun convertUploadContact(receiverIds: String?): String {
    val list = ArrayList()
    if (!TextUtils.isEmpty(receiverIds)) {
        val sArr = receiverIds!!.split("$")
        for (ss in sArr) {
            if(!ss.equals(""))
            list.add(UploadContact(ss))
        }
    }
    return toJSONString(list)
}

2、 Java版

public String convertUploadContact(String receiverIds) {
    ArrayList list = new ArrayList<>();
    if (!TextUtils.isEmpty(receiverIds)){
        String[] sArr=receiverIds.split("\\$");
        for (String ss : sArr) {
            list.add(new UploadContact(ss));
        }
    }

    return ToolUtils.toJSONString(list);
}
