什么是反斜杠字符（\\）？ [英] What is the backslash character (\\)?

问题描述

什么是字符串文字 \\ 反斜杠？它有什么作用？我已经考虑过了，但我不明白。我也在维基百科上阅读了它。当我尝试打印以下内容时：

What is the string literal \\ backslash? What does it do? I have thought about it but I do not understand it. I also read it on wikipedia. When I try to print the following:

System.out.println("Mango \\ Nightangle");

输出为： Mango \ Nightangle

这个字符串文字有什么意义？

What is the significance of this string literal?

推荐答案

\ 用于许多编程语言（包括Java）中的转义序列。

\ is used as for escape sequence in many programming languages, including Java.

如果你想

• 转到下一行然后使用 \ n 或 \ r ，


• 供标签使用 \t


• 同样打印 \ 或这是特殊的字符串文字，你必须用另一个 \ 来转义它，它给我们 \\ 和 \

• go to next line then use \n or \r,
• for tab use \t
• likewise to print a \ or " which are special in string literal you have to escape it with another \ which gives us \\ and \"
