Answer

✐ Examples

1 Check if String contains specific Character using 'contains' method

In this example,

We create a function 'containsCharacter' that takes a string and a character as input.
We use the 'contains' method of the string object to check if the character is present in the string.
If the character is found, 'true' is returned; otherwise, 'false'.
Finally, we print the result.

Kotlin Program

fun containsCharacter(str: String, ch: Char): Boolean {
    return str.contains(ch)
}

fun main() {
    val str = "Hello World"
    val ch = 'W'
    val contains = containsCharacter(str, ch)
    println("String contains character '$ch': $contains")
}

Output

String contains character 'W': true
