在Scala中读取文本文件

import scala.io.Source

def readFile(filePath: String): String = {
  val source = Source.fromFile(filePath)
  val content = source.mkString
  source.close()
  content
}

val filePath = "path/to/file.txt"
val fileContent = readFile(filePath)
println(fileContent)

import java.io.BufferedReader
import java.io.FileReader

def readFile(filePath: String): String = {
  val reader = new BufferedReader(new FileReader(filePath))
  val content = Iterator.continually(reader.readLine()).takeWhile(_ != null).mkString("\n")
  reader.close()
  content
}

val filePath = "path/to/file.txt"
val fileContent = readFile(filePath)
println(fileContent)
