How to add a LineBreak (\n) to a String.format with fixed String as format?

Question

In the code below, message is a final String that have a \n inside it, and it doesn't work.

message = format = "Blah %d Blah Blah \nBlah Blah %s Blah"
interventionSize = number
UserID = String
String.format(Dic.message,interventionSize,userID)

How can I make the line break in this case, cannot find an answer.

BTW, I cannot use any kind of framework or external jar to do that (old code) have to use Plain Old Java.

Answer 1

Having \n in a format string is just fine.

Perhaps you should try a platform specific new-line. With format strings you can use %n.

That is, try the following:

String.format(Dic.message.replace("\\n", "%n"), interventionSize, userId);
