Question

I am writing out a String and i need it to break the lines every time there is 20 characters on a line.
However, it counts the

\n

as a character as well. How can i break the lines when there is 20 characters on the line, excluding the \n?

Edit: Every time it’ve counted 20 characters, it adds \n to the end of the line

Answer 1

Before printing your string, get rid of the containing line breaks like this:

yourString = yourString.replaceAll("\\n", "");

Here "\\n" is a regular expression matching the newline character. The string literal "\\n" is actually a string containing \n
