Writing a "\n" in a text file

I'm trying to write a string \n in a text file. But the result in the text file is a newline. I know that the \n represents a newline. But in my case, I really need to see the String \n, not the newline. How can I solve this?

The \ character escapes the next character, as you say \n will create a newline. If you wish to output an actual \, you need to write:

"\\n"

That way the first slash escapes the second slash, generating an actual slash rather than escaping the n.

What you want is to print two characters, namely \ and n. According to your language's manual, to print \ you must escape it. n is not among the characters you must escape. Therefore, you write \\ and n, thus \\n.

You need to escape the \. This can be done by entering \\.

Use "\\n". The first backslash escapes the second one and as a result one is printed to your output.

Do you mean

pw.print("\\n"); // print \ and n

instead of

pw.print("\n"); // print new line.

you have to escape the backslash, so double it:

out("\\n")
