Scala program to demonstrate the partially applied function

Here, we are going to demonstrate the partially applied function in Scala programming language.
Submitted by Nidhi, on May 28, 2021

Problem Solution:

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

Program/Source Code:

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));


Result: 60


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.
