Scala – Creating function with arguments

Here, we will define a function with two arguments. And, we will pass two integer arguments to add both numbers and print the result on the console screen.

Scala code to create a function with arguments

The source code to create a function with arguments is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to create a
// function with arguments

object Sample {
  def main(args: Array[String]): Unit = {
    // Function calling
    addNum(10, 20)
  }

  // Function definition
  def addNum(num1: Int, num2: Int): Unit = {
    val result: Int = num1 + num2
    println(s"Addition is: $result")
  }
}

Output

Addition is: 30

Explanation

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

In this program, we defined a function addNum() with two integer arguments num1 and num2.

In the main() function, we called addNum() function with value 10 and 20. The addNum() function add both arguments and print the result on the console screen.
