推荐答案

因为双引号 delimit 字符串值，自然你必须将它们转义为文字双引号，但是你可以做到没有像这样逃脱:

Because double quotes delimit String values, naturally you must escape them to code a literal double quote, however you can do it without escaping like this:

System.out.println('"' + s + '"');

这里，双引号字符 (") 被编码为 char 值.我发现这种风格比笨拙"的反斜杠方法更容易、更清晰易读.但是，这种方法只能在附加单个字符常量时使用，因为char"(当然)正好是一个字符.

Here, the double quote characters (") have been coded as char values. I find this style easier and cleaner to read than the "clumsy" backslashing approach. However, this approach may only be used when a single character constant is being appended, because a 'char' is (of course) exactly one character.
