15.3.4 Java Format Strings

There are two kinds of format strings in Java: those acceptable to the MessageFormat.format function, labelled as ‘java-format’, and those acceptable to the String.format and PrintStream.printf functions, labelled as ‘java-printf-format’.

Java format strings are described in the JDK documentation for class java.text.MessageFormat, https://docs.oracle.com/javase/7/docs/api/java/text/MessageFormat.html. See also the ICU documentation http://icu-project.org/apiref/icu4j/com/ibm/icu/text/MessageFormat.html.

Java printf format strings are described in the JDK documentation for class java.util.Formatter, https://docs.oracle.com/javase/7/docs/api/java/util/Formatter.html.
