Although 'toUpperCase' will give the opposite effect, I'll still give you +1 :-)

Fixed (including linking to Java6 docs - does anyone even still use 1.4?) and upvoted.

@Fortega - the OP said "converting between" not "converting from / to". Converting between implies converting in both directions.

Answer 3

+3 A:

Yes. There are methods on the String itself for this.

Note that the result depends on the Locale the JVM is using. Beware, locales is an art in itself.

Yup. I recently discovered that the size of string is not always the same as the size of string.toUpperCase()

Fortega 2009-12-23 10:19:12

Yes but only in those weird languages with umlauts and Eszett and names like Thorbjørn :-)

paxdiablo 2009-12-23 10:33:59

you mean like weird languages like every other language on the planet?

Actually we use ISØ-Låtin-1 here in Sĉändïñävïä so it could be a LØT WØRSË :)

Answer 4

+1 A:

Hi, There are methods in the String class; toUppercase() and toLowerCase().

i.e.

String input = "Cricket!";
String upper = input.toUpperCase(); //stores "CRICKET!"
String lower = input.toLowerCase(); //stores "cricket!"

This will clarify your doubt

How do I convert strings between uppercase and lowercase in Java?
