In Scala, reading from and writing to files on file-system is very easy.
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".

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.
