How to Iterate over Characters in String in Kotlin ?

To iterate over characters in a string in Kotlin, you can use various methods such as indices, forEach, or for loop with the char indices.

In this example,

We create a string named str with a value of "Hello".
We use the indices property of the string to get the range of valid indices for the string.
We iterate over the indices using a for loop and access each character using str[index].
Finally, we print each character to standard output.

fun main() {
    val str = "Hello"
    for (index in str.indices) {
        println(str[index])
    }
}

In this example,

We create a string named str with a value of "World".
We call the forEach method on the string and provide a lambda function that takes each character as input and prints it.
The forEach method iterates over each character in the string.
Finally, we print each character to standard output.

fun main() {
    val str = "World"
    str.forEach { char ->
        println(char)
    }
}
