[wuchiuwong]

Affects PMD Version:
6.22.0

Rule:
UseLocaleWithCaseConversions

Description:
UseLocaleWithCaseConversions could additionally check String.format(foo, bar)
Similar to toLowerCase() and toUpperCase, String.format(foo, bar) also need to specify a locale when calling the methods

Code Sample demonstrating the suggestion:

capture = String.format("You zoomed in %.2f%%.\n", percent);

// better
capture = String.format(Locale.ROOT, "You zoomed in %.2f%%.\n", percent);
