在Scala中将字典保存为.txt文件

import java.io.PrintWriter
import scala.collection.mutable.Map

val dictionary = Map("apple" -> "苹果", "banana" -> "香蕉", "orange" -> "橙子")

val filePath = "dictionary.txt"

val writer = new PrintWriter(filePath)

dictionary.foreach { case (key, value) =>
  writer.println(s"$key:$value")
}

writer.close()
