How can I replace all line breaks from a string in Java in such a way that will work on Windows and Linux (ie no OS specific problems of carriage return/line feed/new line etc.)?
I've tried (note readFileAsString is a function that reads a text file into a String):
String text = readFileAsString("textfile.txt");
text.replace("\n", "");
but this doesn't seem to work.
How can this be done?
String text = readFileAsString("textfile.txt").replaceAll("\n", "");
Even though the definition of trim() in oracle website is "Returns a copy of the string, with leading and trailing whitespace omitted."
the documentation omits to say that new line characters (leading and trailing) will also be removed.
In short
String text = readFileAsString("textfile.txt").trim(); will also work for you.
(Checked with Java 6)
String text = readFileAsString("textfile.txt").replace("\n","");
.replace returns a new string, strings in Java are Immutable.
