在Java中，我应该转义单引号（'）在字符串（双引号）？ [英] In Java, should I escape a single quotation mark (') in String (double quoted)?

问题描述

在Java中， \'表示单引号（单引号）字符， \

In Java, \' denotes a single quotation mark (single quote) character, and \" denotes a double quotation mark (double quote) character.

所以， String s =I\'ma human。;

So, String s = "I\'m a human."; works well.

但是， String s =我是人类。

同样， char c ='\'; code> char c ='';

Likewise, char c = '\"'; works, but char c = '"'; also works.

在Java中，哪个更好用？ ，像 style =font-family：'Arial Unicode MS';这样的东西更常见（对于这样的标签，我认为这是使用引号的唯一方法） ，但在Java中，我通常看到人们使用转义字符，例如I \'ma human。

In Java, which is better to use? In HTML or CSS, things like style="font-family:'Arial Unicode MS';" are more often (and for such tags, I think it's the only way to use quotation marks), but in Java, I usually saw people use escape characters like "I\'m a human."

推荐答案

您不需要转义字符串中的'字符（包含在），并且不必在char中包含字符（包含在'中） 。

You don't need to escape the ' character in a String (wrapped in "), and you don't have to escape a " character in a char (wrapped in ').
