Scala - Assessment - Write to a file

In Scala, reading from and writing to files on file-system is very easy. After importing java.io._, you can use an instance of PrintWriter to write to a file.

For example, to write string "Hello" to a file named test.txt, you can use below code:

val writer = new PrintWriter(new File("new.txt" ))
writer.write("Hello")
writer.close()

Now, let's write a Scala program which will write below 2 phrases in 2 lines in a file named "New.txt".

Hello Scala
Bye Scala

To write the second line into a new line, write a new line character to the file after the first line.

New line character is indicated by "\n". so, you will write "Hello Scala", then "\n" followed by "Bye Scala" to the file.
