如何将字符数组转换回字符串？ [英] How to convert a char array back to a string?

问题描述

我有一个字符数组：

char[] a = {'h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd'};

我目前的解决办法是做

My current solution is to do

String b = new String(a);

但肯定有这样做的更好的办法？

But surely there is a better way of doing this?

推荐答案

没有，该解决方案是完全正确和非常小的。

No, that solution is absolutely correct and very minimal.

不过请注意，这是一个非常不寻常的情况：因为字符串是专门在Java中处理，甚至foo的实际上是一个字符串。所以不需要在正常code代表将字符串分割成单独的字符和他们一起回来的必要。

Note however, that this is a very unusual situation: Because String is handled specially in Java, even "foo" is actually a String. So the need for splitting a String into individual chars and join them back is not required in normal code.

比较这对C / C ++，其中foo的你的字符 S按零终止的包它们之间的字节一边和字符串在另一边，许多因转换遗留做的方法。

Compare this to C/C++ where "foo" you have a bundle of chars terminated by a zero byte on one side and string on the other side and many conversions between them due do legacy methods.
