java - Is there Simple way to use String.toLowerCase() for 9 kinds of languages? -

i need treat 9 kinds of language in list below.

• dutch
• english
• french
• german
• italian
• portuguese
• russian
• spanish
• ukrainian

for words in these languages need use tolowercase(). , know need use locale(country, language) parameter of function. then, have use specific locale each language, or there simpler way this?

you can construct locale iso 639 language code:

locale russian = new locale("ru"); 

there nice default locales use, example:

locale english = locale.english; locale french = locale.french; locale german = locale.german; locale italian = locale.italian; 

then use string#tolowercase() locale:

string lower = str.tolowercase(somelocale);
