import java.io.BufferedReader
    import java.io.File
    
    fun main(args: Array<String>) {
        val filePath = "./myfile.txt"
        val file = File(filePath)
        val reader = BufferedReader(file.reader())
    
        var string: String? = null
        while (true) {
            string = reader.readLine()
            if (string == null) {
                break
            } else {
                println(string)
            }
        }
    }

或者：

import java.io.File
    
    fun main(args: Array<String>) {
        val filePath = "./myfile.txt"
        val file = File(filePath)
        val bufferedReader = file.reader().buffered()
    
        var line: String?
        while (true) {
            line = bufferedReader.readLine()
            if (line != null) {
                println(line)
            } else {
                break
            }
        }
    
        bufferedReader.close()
    }
