如何在Kotlin中仅读取文本文件中的指定行？

import java.io.File

fun readSpecificLine(filePath: String, lineNumber: Int): String? {
    File(filePath).forEachLine { line ->
        if (--lineNumber == 0) {
            return line
        }
    }
    return null
}

fun main() {
    val filePath = "path/to/your/file.txt"
    val lineNumber = 5 // 指定行号
    val line = readSpecificLine(filePath, lineNumber)
    println("Line $lineNumber: $line")
}

import kotlin.io.Files
import java.nio.file.Paths

fun readSpecificLine(filePath: String, lineNumber: Int): String? {
    return Files.readAllLines(Paths.get(filePath)).getOrNull(lineNumber - 1)
}

fun main() {
    val filePath = "path/to/your/file.txt"
    val lineNumber = 5 // 指定行号
    val line = readSpecificLine(filePath, lineNumber)
    println("Line $lineNumber: $line")
}
