To use a keyboard shortcut to change between lowercase, UPPERCASE, and Capitalize Each Word, select the text and press SHIFT + F3 until the case you want is applied.
Java String toUpperCase() Method The toUpperCase() method converts a string to upper case letters. Note: The toLowerCase() method converts a string to lower case letters.
string str = "something"; str[0] = toupper(str[0]); That's all you need to do.
If you need the upper case for presentation to your views, you can simply use css for do so!
div.capitalize:first-letter {
text-transform: capitalize;
}
