*
* <p> For example:

* "a", "b", "c", "d")
* // -> "d c b a d c b a"
* </pre></blockquote>
*
* <li> <i>Relative indexing</i> is used when the format specifier contains a

* // "c" and "d" are ignored because they are not referenced}
* </pre></blockquote>
*
* <li> <i>Ordinary indexing</i> is used when the format specifier contains
* neither an argument index nor a {@code '<'} flag. Each java.lang.StringIndexOutOfBoundsException: Index 63 out of bounds for length 29
* which uses ordinary indexing is assigned a sequential implicit index into
* argument list which is independent of the indices used by explicitor
* relative indexing.
*
* <blockquote><pre>

* // -> "a b c d"

* // -> "b a a b"
* // "c" and "d" are ignored because they are not referenced
* </pre></blockquote>
*
* <p> The maximum number of arguments is limited by the maximum dimension of a
* Java array as defined by
* <cite>The Java Virtual Machine Specification</cite>.
* If the argument index does not correspond to an
* available argument, then a {@link MissingFormatArgumentException} is thrown.
