如何在Kotlin中将String转换为Int？

fun main() {
    val numberString = "123"
    try {
        val number = numberString.toInt()
        println("转换后的整数是: $number")
    } catch (e: NumberFormatException) {
        println("无法将字符串转换为整数: ${e.message}")
    }
}

fun main() {
    val invalidString = "abc"
    try {
        val number = invalidString.toInt()
        println("转换后的整数是: $number")
    } catch (e: NumberFormatException) {
        println("无法将字符串转换为整数: ${e.message}")
    }
}

fun main() {
    val largeNumberString = "2147483648"
    try {
        val number = largeNumberString.toLong()
        println("转换后的长整数是: $number")
    } catch (e: NumberFormatException) {
        println("无法将字符串转换为长整数: ${e悯息.message}")
    }
}
