In Scala, the Try, Success, and Failure classes provide a functional way to handle exceptions and errors. This approach allows you to work with the concept of success and failure as data, rather than using traditional try-catch blocks. Here is an overview of how to use Try, Success, and Failure for error handling in Scala:

scalaCopy code
import scala.util.{Try, Success, Failure}

// Simulating a function that may throw an exception
def divide(x: Int, y: Int): Try[Int] = Try(x / y)

// Using pattern matching to handle Trys Success and Failure
divide(10, 2) match {
  case Success(result) => println(s"Result: $result")
  case Failure(exception) => println(s"Exception: ${exception.getMessage}")
}

In this example:

• The divide function uses the Try class to handle the division operation that may throw an exception if the divisor is 0.
• The match expression is used to pattern match the result of the divide function. If the division is successful, it prints the result. If an exception occurs, it prints the exception message.

Using Try, Success, and Failure is a functional way to handle errors in Scala, enabling you to manage exceptional situations while leveraging the benefits of functional programming.
