Scala – Returning Match Case Value from a Method

Here, we will demonstrate that how we can return match case value from a method? The match statement is similar to the switch statement of other programming languages. Here, we will define specific cases. In the match statement case underscore (case _) is used for the default case.

Scala code to return match case value from a method

The source code to return the match case value from a method is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to return the match case value from a method

object Sample {
    // Method to return match case value
    def Fun(number: Int): String = {
        number match {
            case 1 => "One"
            case 2 => "Two"
            case 3 => "Three"
            case 4 => "Four"
            case _ => "Unknown number"
        }
    }

    def main(args: Array[String]): Unit = {
        // Calling the method with input value
        val res = Fun(3)
        println(res) // Output: Three
    }
}

Output

Three

Explanation

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

Here, we also defined a Fun() method, that returns the match case value based on the given parameter

In the main() function, we called the Fun() method with value 3 and assigned the returned value to the variable res and printed the result on the console screen.
