How to create a map with key type point (x, y) and value type string in Scala

Answer 1

object PointMapApp extends App {

  case class Point(x: Int, y: Int) {
    def getX: Int = x
    def getY: Int = y
  }

  // Create a map with Point keys and String values
  val pointMap: Map[Point, String] = Map(
    Point(2, 7) -> "A",
    Point(3, 6) -> "B",
    Point(0, 0) -> "C"
  )

  // Print x and y separately
  for ((point, value) <- pointMap) {
    println(s"x: ${point.getX}, y: ${point.getY} => $value")
  }
}

 
 
/*
run:
  
x: 2, y: 7 => A
x: 3, y: 6 => B
x: 0, y: 0 => C
  
*/
