Java: possible to line break in a properties file?

Question

Is it possible to continue a long string on the next line in a Java properties file?

e.g., somehow

myStr=Hello
      World

and when I g

Answer 1

myStr = Hello \
        World

The backslash tells the application to continue reading the value onto the next line. ^^

Answer 2

A backslash at the end of a line lets you break across multiple lines, and whitespace that starts a line is ignored:

myStr = Hello \
        World

The Java docs put it this way:

A logical line holds all the data of a key-element pair, which may be spread out across several adjacent natural lines by escaping the line terminator sequence with a backslash character \.

Answer 3

You need to use \n\ as a solution.

First two symbols \n - new line for string, third \ - multi-line in properties file.

For example (in application.properties):

mail.bodyText=Hello.\n\
This is notification.
