Answer

To append a character to the end of a string in Kotlin, you can use the plus operator or StringBuilder.

✐ Examples

1 Append Character '!' to "Hello World"

In this example,

We create a string variable str1 with the value "Hello World".
We then append the character '!' to str1 using the plus operator.
Finally, we print the modified string str1 to standard output.

Kotlin Program

fun main(args: Array<String>) {
    var str1 = "Hello World"
    str1 += '!'
    println("Appended String: $str1")
}

Output

Appended String: Hello World!

2 Append Character '!' to "apple"

In this example,

We create a string variable str2 with the value "apple".
We then use StringBuilder to append the character '!' to str2.
Finally, we print the modified string str2 to standard output.

Kotlin Program

fun main(args: Array<String>) {
    var str2 = "apple"
    val stringBuilder = StringBuilder(str2)
    stringBuilder.append('!')
    println("Appended String: $stringBuilder")
}

Output

Appended String: apple!
