如何从目录中读取文件并查找具有特定扩展名-scala的文件

import java.io.File

def findFilesWithExtension(directory: File, extension: String): List[File] = {
  if (directory.isDirectory) {
    val files = directory.listFiles.toList
    val matchingFiles = files.filter(file => file.isFile && file.getName.endsWith(extension))
    val subDirectories = files.filter(_.isDirectory)
    matchingFiles ++ subDirectories.flatMap(subDirectory => findFilesWithExtension(subDirectory, extension))
  } else {
    List.empty[File]
  }
}

val directoryPath = "/path/to/directory"
val extension = ".scala"
val directory = new File(directoryPath)
val matchingFiles = findFilesWithExtension(directory, extension)

matchingFiles.foreach(println)
