Scala – Partially Applied Function

Here, we will demonstrate the partially applied function. Here we can escape argument at the time of function call using underscore(_).

Scala code to demonstrate the example of partially applied function

The source code to demonstrate the partially applied function is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to demonstrate
// the partially applied function

object Sample {
  def main(args: Array[String]) {
    val AddNums = (num1: Int, num2: Int, num3: Int) => num1 + num2 + num3

    // Call partially applied function.
    val result = AddNums(10, 20, _: Int);

    printf("Result: %d\n", result(30));
  }
}

Output

Result: 60

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 the main() function, we defined an anonymous function to add three integer numbers. And, called function by escaping the third argument. After that, we passed the third argument and print the result on the console screen.
