How to Remove First Char In Kotlin String?

To remove the first character from a Kotlin string, you can use the substring function. You can specify the starting index as 1 to exclude the first character, like this:

1
2

val originalString = "example"
val stringWithoutFirstChar = originalString.substring(1)

In this example, stringWithoutFirstChar will be equal to "xample", with the first character removed from the original string.

How do you remove the starting character in a Kotlin string?

You can remove the starting character in a Kotlin string by using the substring() function. Here is an example of how you can do this:

1
2
3
4
5

val str = "Hello"
if (str.isNotEmpty()) {
    val newStr = str.substring(1)
    println(newStr) // Output will be "ello"
}

In this example, substring(1) is used to remove the first character of the string "Hello" and the resulting string "ello" is printed to the console.

What is the best way to eliminate the initial character in a Kotlin string?

One way to eliminate the initial character in a Kotlin string is to use the substring function. Here's an example code snippet demonstrating how to do this:

1
2
3
4
5
6

fun main() {
    val originalString = "example"
    val newString = originalString.substring(1)
    
    println(newString)
}

In this code snippet, the substring function is called on the original string starting from index 1, which skips the initial character in the string. The resulting newString will have the initial character eliminated.

How to drop the first character from a Kotlin string without changing the original?

You can drop the first character from a Kotlin string without changing the original string by using the substring function. Here's an example:

1
2
3
4
5
6
7

fun main() {
    val originalString = "hello"
    val newString = originalString.substring(1)
    
    println("Original String: $originalString")
    println("New String: $newString")
}

Output:

1
2

Original String: hello
New String: ello

In this example, the substring(1) function is used to create a new string by skipping the first character of the original string. The original string remains unchanged.
