Common functions in the SCALA IO File framework

The SCALA IO File framework is a powerful library for processing files and directory.It provides many commonly used functions that facilitate developers to perform file operations. 1. Create a file or directory: Use the `Createfile` function to create a new file, and use the` createdirectory` function to create a new directory. scala import scalax.io.File val file = File("path/to/file.txt") file.createFile() val directory = File("path/to/directory") directory.createDirectory() 2. Write file: Use the `write` function to write to the file.You can pass a string or byte array as a parameter. scala val text = "Hello, World!" file.write(text) val bytes = Array[Byte](1, 2, 3) file.write(bytes) 3. Read file: Use the `Lines` function to read the file content one by one, and return a` Iterator [String] `. scala val lines = file.lines() lines.foreach(println) 4. Copy file or directory: Use the `Copyto` function to copy the file or directory to the specified position. scala val destination = File("path/to/destination/file.txt") file.copyTo(destination) 5. Move file or directory: Use the `MOVETO` function to move the file or directory to the specified position. scala val destination = File("path/to/destination/file.txt") file.moveTo(destination) 6. Delete file or directory: Use the `Delete` function to delete the file or directory. scala file.delete() 7. Check whether the file or directory exists: Use the `exists` function to check whether the file or directory exists. scala if (file.exists) { println("File exists.") } 8. Get the path of the file or directory: Use the `Path` function to obtain the path of the file or directory. scala val path = file.path println(path) 9. Get the size of the file or directory: Use the `size` function to obtain the size (byte number) of the file or directory. scala val size = file.size println(size) 10. Check whether the file or directory can be written: Using the `iSwriteable` function can check the file or directory whether it can be written. scala if (file.isWriteable) { println("File is writeable.") } The above are some common functions in the SCALA IO FILE framework.We can use these functions to create, read, write, copy, move, delete, and other operations of files and directory.Using Scala IO File, developers can easily handle file operations to improve development efficiency.
