\x在Java中逃脱？ [英] \x Escape in Java?

问题描述

我想知道Java中是否存在类似于C ++中的类似hex（\x）转义。
例如：

I was wondering if there is a similar hex (\x) escape in Java like there is in C++. For example:

char helloworld[] = "\x48\x45\x4C\x4C\x4F\x20\x57\x47\x52\x4C\x44";
printf("%s", helloworld);

到目前为止，Java中没有hex（\x）转义。有没有一个替代方法是一样容易使用，而不必将一堆十六进制数字连接在一起？

There is no hex (\x) escape in Java from what it appears so far. Is there an alternative that is just as easy to use without having to concat a bunch of hex numbers together?

推荐答案

Java中的字符串始终以UTF-16编码，因此它使用Unicode转义： \\\H 。支持八进制字符： \110

Strings in Java are always encoded in UTF-16, so it uses a Unicode escape: \u0048. Octal characters are supported as well: \110
