How to get Length of String in Kotlin - Step by Step Examples

How to get Length of String in Kotlin ?

To get the length of a given string in Kotlin language, you can use length property of the String object.

In this example,

We create a string named str1 with an string value of "Hello World".
We then get the length of the string using length property of the string object str1, and store the returned value in length variable.
String.length property returns the length of this string.
Finally, we shall print the value in length to standard output.

fun main(args: Array<String>) {
    val str1 = "Hello World";
    val length = str1.length
    print("Length of given string is: $length");
}

Length of given string is: 11

In this example,

We take a string value of "apple" in variable named str2.
We then get the length of the string using length property of the string object str2, and store the returned value in length variable.
String.length property returns the length of this string.
Finally, we shall print the value in length to standard output.

fun main(args: Array<String>) {
    val str2 = "apple";
    val length = str2.length
    print("Length of given string is: $length");
}

Length of given string is: 5
