In java how to identify that the provided string ends with newline character or not?
A newline is an OS-dependant concept. On Unix it’s one character (linefeed – U+000A), on Windows it’s two characters (carriage return + linefeed, U+000D U+000A), it could be ven the newline character (NEL, U+0085, which I think may be used by some mainframes).
Some regular expression engines accept
\Rto mean a newline. Tom Christiansen defines\Rfor Java as the following:at this answer.
Then, you would use a regex like
\R$, or, in Java\\R$, to mean “ends in newline”.
