Writing a “\n” in a text file

Question

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?

Answer 1

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.

Answer 2

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

Answer 3

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

Answer 4

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.

Answer 5

Do you mean

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

instead of

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

Answer 6

you have to escape the backslash, so double it:

out("\\n")
