Scala String toCharArray() Method

By IncludeHelp Last updated : October 21, 2024

Description and Usage

The toCharArray() method defined on string is used to convert the given string to a character array (charArray).

Syntax

string_Name.toCharArray()

Parameters

The method is a parameter-less method i.e. it does not accept any parameter.

Return Value

It returns a charArray.

Example 1

object MyClass {
    def main(args: Array[String]) {
        val myString = "scala Programming Language"
        println("The string is '" + myString + "'")
        
        val char_array = myString.toCharArray()
        println(char_array)
        
        println("Printing the char_array : ")
        for(i <- char_array)
            print(i + " ")
    }
}

Output

The string is 'scala Programming Language'
[C@61e45f87
Printing the char_array : 
s c a l a   P r o g r a m m i n g   L a n g u a g e

In the above code, we have accessed charArray using its name which returns [C@61e45f87 which is the location of the first character. And to print we need to print it character by character.

Example 2

object MyClass {
    def main(args: Array[String]) {
        val myString = ""
        println("The string is '" + myString + "'")
        
        val char_array = myString.toCharArray()
        println(char_array)
        
        println("Printing the char_array : ")
        for(i <- char_array)
            print(i + " ")
    }
}

Output

The string is ''
[C@61e45f87
Printing the char_array :
