Here, we will create a program to handle the exception. And, we will use try and catch blocks. The source code written inside the try block may generate an exception. Then we handle generated exceptions in catch block and print exact exception messages using case exception.

Program/Source Code:

The source code to handle multiple exceptions is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to print exact exception message

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);
    }
  }
}

Output:

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

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.
