how to assign array values to individual int variables using scala-CodePudding

I am trying achieve the below in scala

var date="12/01/2021"
var a,b,c = date.split("/")
print(a,b,c)

//expected result 
12,01,2021

CodePudding user response：

You can write

val Array(a,b,c) = date.split("/")

val Array(a,b,c) = date.split("/").take(3)

However, the pattern match as @Gaël J suggested has the advantage of graceful handling of cases where the result doesn't have the 3 parts expected

CodePudding user response：

There's no way you know for sure the size of the array after splitting, which is why you cannot destructure it like this.

However you can use pattern matching:

date.split("/") match {
  case Array(a, b, c) => print(...)
  case _ => print("invalid format")
}

Or just access the array by index (not safe):

val arr = date.split("/")
val (a, b, c) = (arr(0), arr(1), arr(2))
