Syntax:

string_Name.charAt(index)

Parameters: The method accepts a single parameter which is the index of the character to be found.

Return Value: It returns a character which is found at the given index.

Example 1: Program to illustrate the working of charAt() method

object myObject {
    def main(args: Array[String]) {
        val myString = "scala"
    
        println("The string is '" + myString + "'")
    
        println("Character at index 4 is " + myString.charAt(4))
    }
}

Output:

The string is 'scala'
Character at index 4 is a

Example 2: Program to print characters of string

object myObject {
    def main(args: Array[String]) {
        val myString = "scala"
        println("The string is '" + myString + "'")

        val stringLen = myString.length()
        println("Printing the string character by character :")

        for(i <- 0 to (stringLen - 1) )
            println(myString.charAt(i))
    }

Output:

The string is 'scala'
Printing the string character by character :
