+For code that should work on varying operating systems Java offers [`System.lineSeparator()`][system-line-separator], which returns the system-dependent line separator string.
+This is important if you're writing to files that will be read on the same system.

+To comfortable work with texts that contain a lot of newlines you can use [Text Blocks][text-blocks].
+These multi-line strings are delimited by triple double quote (`"`) characters.
