Split Java String by New Line

Question

I\'m trying to split text in a JTextArea using a regex to split the String by \\n However, this does not work and I also tried by \\r\\n|\\r|

Answer 1

There are three different conventions (it could be said that those are de facto standards) to set and display a line break:

• carriage return + line feed
• line feed
• carriage return

In some text editors, it is possible to exchange one for the other:

The simplest thing is to normalize to line feedand then split.

final String[] lines = contents.replace("\r\n", "\n")
                               .replace("\r", "\n")
                               .split("\n", -1);
