Introduction to SCALA IO File framework
Scala IO is a Scala library for file operation.It provides a simple and easy -to -use API, allowing developers to easily read, write, copy, move, and delete files.
The core function of Scala IO includes:
1. File and directory operation: SCALA IO provides a series of methods to create, delete and rename files and directory, and obtain their attributes (such as file size, creation time, etc.).
Here are some commonly used files and directory operation examples:
scala
import scalax.io._
import java.io.File
// Create a new file
val file = new File("path/to/file.txt")
file.createNewFile()
// Delete Files
file.delete()
// Rename files
val renamedFile = new File("path/to/renamed_file.txt")
file.renameTo(renamedFile)
// Create a new directory
val dir = new File("path/to/directory")
dir.mkdir()
// Delete the directory
dir.delete()
2. Reading and writing of files: Scala IO provides various methods to read and write the content of the file.It supports reading and writing files in different encoding formats according to the line of reading and reading.
Here are some commonly used file reading and writing operation examples:
scala
import scalax.io._
// Read the entire file
val fileContent = Resource.fromFile("path/to/file.txt").string
// Read the file according to the line
val lines = Resource.fromFile("path/to/file.txt").lines()
// Write the file
Resource.fromFile("path/to/file.txt").write("Hello, World!")
3. Copy, move, and traversal of files: Scala IO provides methods to copy, move files, and traverse directory.
Here are some commonly used file copying, movement, and traversal operation examples:
scala
import scalax.io._
import java.io.File
// Copy files
val sourceFile = new File("path/to/source_file.txt")
val targetFile = new File("path/to/target_file.txt")
sourceFile.copyTo(targetFile)
// Mobile files
val sourceFile = new File("path/to/source_file.txt")
val targetFile = new File("path/to/target_file.txt")
sourceFile.moveTo(targetFile)
// Traversing directory
val dir = new File("path/to/directory")
dir.listFiles().foreach { file =>
println(file.getName)
}
All in all, SCALA IO is a convenient file operation library that provides many methods for files and directory operations.Whether it is reading, writing, copying, moving or deleting files, SCALA IO can provide simple and easy -to -use solutions.
