Here, we will use the finally block without the catch block. And, we will use the try and finally block. And, exceptions may be generated in the try block, but it will not be handled.

Program/Source Code:

The source code to demonstrate the finally block without catch 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 without catch block

object Sample {
  // Main method
  def main(args: Array[String]) {
    var arr = Array(1, 2, 3, 4, 5);
    var cnt = 0;
    try {
      println("Array elements: ");
      while (cnt < 5) {
        printf("%d ", arr(cnt));
        cnt = cnt + 1;
      }
      println();
    } finally {
      println("Finally block executed")
    }
  }
}

Output:

Array elements: 
1 2 3 4 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. Then we accessed and print array elements in the try block. After that, the finally block gets executed and then printed "Finally block executed" message on the console screen.
