For Java it's debatable: the Java 5 string formatting APIs are all printf-style (java.io.PrintStream#printf[0], String#format[1], java.util.Formatter[2]).

The older java.text.MessageFormat[3] (still used a lot for property lists as it's built for localization among other things) does use {}-style, though one quite different than Python's.
