Java的：String.toCharArray（）与UNI code字 [英] Java: String.toCharArray() with unicode characters

问题描述

我知道字符不能包含统一code字符（如字符c ='\\ u1023'）。所以，我怎么会去这样做。

I know that char cannot contain Unicode characters (like char c = '\u1023'). So how would I go about doing

    String s = "ABCDEFG\u1023";
    char[] c = s.toCharArray();

我想送我必须通过每一个字符在可能很长的字符串这是低效转换为CharArray出于性能的考虑到循环。任何有达到同样的效果是好的。

I would like to convert s to a CharArray for performance reasons as I have to loop through every character in a potentially very long string which is inefficient. Anything which achieves the same result is fine.

非常感谢！

编辑：
其实字符可以包含单code字符。我只是愚蠢。由于这些反正谁帮助了。

Actually char can contain unicode chars. I'm just being stupid. Thanks to those who helped out anyway.

推荐答案

谁告诉你，在Java中字符不能包含统一code字，<一个HREF =htt​​p://java.sun.com/docs/books/jls/third_edition/html/typesValues​​.html#4.2.1>错了：

Whoever told you that in Java char can't contain Unicode characters, was wrong:

积分类型的值是整数在以下范围：

The values of the integral types are integers in the following ranges:

  
• 对于字符，从'\\ u0000的到'\\ uffff包容性，即从0到
    65535

  

• For char, from '\u0000' to '\uffff' inclusive, that is, from 0 to 65535
