Scala program to return match case value from a method

Here, we are going to learn how to return match case value from a method in Scala programming language?
Submitted by Nidhi, on April 28, 2021

Problem Solution:

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.

Program/Source Code:

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 method

object Sample {
    def Fun(num:Any):Any = num match{  
        case 1 => "One"
        case 2 => "Two"
        case 3 => "Three"
        case 4 =>  "Four"
        case _ => "Unknown number"
    }
    
    def main(args: Array[String]) {  
        var res=Fun(3)
        println(res)
    }  
} 

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.
