(`CompactNumberFormat` does for its own purpose (https://bugs.openjdk.org/browse/JDK-8222756), but not for general use) For this case, I think `ChoiceFormat` is the mid-ground solution, as Swing is only localized in a handful of languages.

another suggestion: to avoid locale-dependent complexity simply show the number of bytes as a number if length < 1000.  this will also avoid involving the group separator - as far as I know, no language on earth uses group separator for numbers in the range 0...999

0 - "0"
1 - "1"
999 - "999"
1000 - "1 KB"
etc.
