Scala program to demonstrate the finally block

Here, we are going to demonstrate the finally block in Scala programming language.
Submitted by Nidhi, on June 07, 2021

Problem Solution:

Here, we will create a program to handle the exception. And, we will demonstrate the finally block. The finally block is used to release resources during exception. The finally block is always executed, whether an exception is generated or not.

Program/Source Code:

The source code to demonstrate the finally block is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to demonstrate the finally block

object Sample {
  // Main method
  def main(args: Array[String]) {
    var arr = Array(1, 2, 3, 4, 5);

    try {
      println(arr(6));
    } catch {
      case e: Throwable => println("Exception message: \n" + e);
    } finally {
      println("Finally block executed")
    }
  }
}

Output:

Exception message: 
java.lang.ArrayIndexOutOfBoundsException: Index 6 out of bounds for length 5
Finally block executed

Explanation:

In the above program, we used an object-oriented approach to create the program. And, we created a singleton object Sample and defined the main() function. The main() function is the entry point for the program.

In the main() function, we created an array of integers with 5 elements. But we used index 6 in the array. That will generate an exception and then we printed the exact exception message on the console screen. After that, the finally block gets executed and the printed "Finally block executed" message on the console screen.
