How do I make a string with a " character in it? (Java)

Question

那几乎是我的问题，我需要做这样的事情：

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

Answer 1

使用\\" 。

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

Answer 2

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\")";

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.

Answer 3

您可以使用转义字符来执行此操作

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