How to Remove Last Character in a String in Kotlin ?

To remove the last character of a string in Kotlin, you can use the substring method with the range from 0 to the length of the string minus 1.

In this example,

We declare a string variable named str1 with a value of "Hello World".
We use the substring method with the range from 0 to the length of the string minus 1 to remove the last character.
Finally, we print the modified string.

fun main() {
    var str1 = "Hello World"
    str1 = str1.substring(0, str1.length - 1)
    println("Modified string is: $str1")
}

Modified string is: Hello Worl

In this example,

We declare a string variable named str2 with a value of "apple".
We use the substring method with the range from 0 to the length of the string minus 1 to remove the last character.
Finally, we print the modified string.

fun main() {
    var str2 = "apple"
    str2 = str2.substring(0, str2.length - 1)
    println("Modified string is: $str2")
}

Modified string is: appl
