Java string formatting

Question

I have a properties file with lines inside, formatted like this:

audit.log.events.purged=The audit events were purged. {0} events were purged, {1} assets were deleted.

Is there a way to bind some values ​​inside these {0} and {1} using some standard APIs, or do I need to create some code to parse these strings

Answer 1

You are looking for MessageFormat: http://java.sun.com/j2se/1.5.0/docs/api/java/text/MessageFormat.html

Answer 2

Java 1.4.2:

String formattedMessage = MessageFormat.format(message, new Object[]{parm1, parm2});

Java 1.5 +:

String formattedMessage = MessageFormat.format(message, parm1, parm2);

In both cases, you can have as many parameters as you want, and not just two.
