将字符串转换为字节然后转换为int

问题描述

我发现了很多与此主题有关的问题，但无法解决我的问题.

I found lots of questions about this topic but i was not able to solve my issue.

用户将输入一个名称 String ，我需要将其转换为 List< int> ，以将其保存在代表名称中每个字符的数据库中.

它可以与拉丁绞接系统配合使用，但是需要与其他书写系统(如阿拉伯或西里尔字母)配合使用.

It is working with latin wring system but this need to be working with other writing system such as arabic or cyrillic script.

List<Integer> intName = new ArrayList<>();
String splitName = currentName.split("");

for (final String currentString : splitConferenceName) {
    final byte[] temp = currentString.getBytes(StandardCharsets.UTF_8);
    final Byte b = temp[0];
    intName.add(b.intValue());
}

我也尝试使用ByteBuffer，但是得到了Bufferunderflowexception.

I also try to use ByteBuffer but got Bufferunderflowexception.
