Scala and Spark for Big Data Analytics

Now, here's the complete example of using try...catch...finally:

package com.chapter3.ScalaFPimport java.io.IOExceptionimport java.io.FileReaderimport java.io.FileNotFoundExceptionobject TryCatch {  def main(args: Array[String]) {    try {      val f = new FileReader("data/data.txt")    } catch {      case ex: FileNotFoundException => println("File not found                                                  exception") case ...
