fn:toUpperCase() – JSTL Function

By Chaitanya Singh | Filed Under: JSTL

It is just opposite of fn:toLowerCase() function. It converts input string to a uppercase string. All the characters of input string gets replaced with corresponding uppercase characters. The string which needs to be changed is provided as an argument to the function and the converted string is being returned by the function. We can pass the string as a variable or simply hard-coding it during function call.

Syntax

String fn:toUpperCase(String input)

It returns the String after converting the input string to uppercase.

Example of fn:toUpperCase()

Here we are converting few strings to their uppercases using the function.
