Scala Program: Destructuring declarations in point class

Last update on June 11 2025 13:10:31 (UTC/GMT +8 hours)

Write a Scala program that creates a class Point with properties x and y coordinates. Use a destructuring declaration to extract the coordinates.

Sample Solution:

Scala Code:

object PointApp {
  def main(args: Array[String]): Unit = {
    val point = Point(2, 1)
    
    val Point(x, y) = point
    
    println(s"x-coordinate: $x")  
    println(s"y-coordinate: $y") 
  }
}

case class Point(x: Int, y: Int)

Sample Output:

x-coordinate: 2
y-coordinate: 1

Explanation:

In the above exercise -

The "Point" class is defined with properties for x and y coordinates. It is a case class, which automatically implements equality, hashing, and toString.
The "PointApp" object contains the main method to test functionality. It creates an instance of the Point class with coordinates (5, 10).
The line val Point(x, y) = point uses a destructuring declaration to extract the x and y values from the point object. This syntax allows you to assign x and y values directly from the point object properties.
Finally, the program prints the extracted x and y coordinates using string interpolation.

Go to:

PREV : MathConstants object with PI and E constants.
NEXT : Enum class for object color representation.
