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>.
