问题描述

这几乎是我的问题，我需要做这样的事情：

Well that was pretty much my question, I need to do something like this:

推荐答案

你正在寻找一种叫做的东西转义序列，这是一种告诉Java将特定字符解释为默认值之外的其他方式的方法。在您的情况下，您可以通过在其前面添加斜杠来创建包含双引号的Java字符串：

You're looking for something called an escape sequence, which is a way of telling Java to interpret a particular character as something other than what it means by default. In your case, you can make a Java string containing a double-quote by prefixing it with a slash:

String scriptContent = "print(\"Hello World\")";

Java中有许多其他转义序列。例如， \\ 代表斜杠字符本身（而不是另一个转义序列的开头！）; \'代表单引号;和 \ n 代表换行符。还有很多其他的;有关详细信息，请参阅Java参考。

There are many other escape sequences in Java. For example, \\ stands for a slash character itself (instead of the start of another escape sequence!); \' stands for a single quote; and \n stands for a newline. There are many others; consult a Java reference for more details.
