How to check if a point is inside a rectangle in Scala

Answer 1

object PointInRectangle {

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

  case class Rectangle(topLeft: Point, bottomRight: Point)

  def isPointInsideRectangle(p: Point, rect: Rectangle): Boolean = {
    p.x >= rect.topLeft.x && p.x <= rect.bottomRight.x &&
    p.y >= rect.topLeft.y && p.y <= rect.bottomRight.y
  }

  def main(args: Array[String]): Unit = {
    val rect = Rectangle(Point(0.0, 0.0), Point(7.0, 7.0))
    val p = Point(3.0, 2.0)

    if (isPointInsideRectangle(p, rect))
      println("The point is inside the rectangle.")
    else
      println("The point is outside the rectangle.")
  }
}
