Formatting a number as hexadecimal using MessageFormat in Java

Question

How do I use MessageFormat to format a number in hexadecimal? I have an existing MessageFormat pattern, and the customer wants to change it from a decimal number to a three-digit hex number. Is this possible using MessageFormat? Or do I have to switch to a more powerful formatter? Or some other trick?

I would use Integer.toHexString() and format the string. You could have a more powerful MessageFormatter by writing your own. – Jinx

Instead of providing a number, provides an hexadecimal String of that number, and stick to MessageFormat. Possibly provide both options with different indexes for better flexibility. – Nordgren

This might do what you want. It's a pluggable ExtendedMessageFormat (extends MessageFormat) commons.apache.org/proper/commons-lang/apidocs/org/apache/… – Jinx

MessageFormat does not support it in the pattern level. – Onceover

@NikhilJain This is not a duplicate. This question is specifically about MessageFormat. – Onceover
