Write in Scala

To write a file in Scala, you need to follow a sequence of steps:

1. Open a file for writing using a PrintWriter object
2. Write data to the file using the print or println methods of the PrintWriter object
3. Close the file using the close method of the PrintWriter object to ensure all data is written and resources are released.

Here is an example Scala code that demonstrates writing to a file:

import java.io._
object WriteToFileExample extends App {

  val fileName = "example.txt"

  val file = new File(fileName)

  val writer = new PrintWriter(file)
writer.println("Scala is awesome!")

  writer.println("Functional programming is the future.")

  writer.println("We can write to files in Scala very easily.")

  writer.close()

}

In this example, we create a new file called example.txt, and then create a PrintWriter object writer to write to the file. We then write three lines of text using the println method and finally we close the file using the close method. After executing this code, you will find the written text in the example.txt file.

Note that if the file specified by fileName already exists, the old contents of the file will be replaced with the new contents written by the PrintWriter object. If you want to append to an existing file instead of overwriting it, you can create the PrintWriter object with the FileWriter object and pass true as the second argument to the FileWriter object constructor.
