val in scala
In Scala, the keyword val
is used to declare an immutable variable. Once a value is assigned to a val
, it cannot be reassigned. Here's an example of how to use val
in Scala:
val x: Int = 5
In this example, x
is declared as a val
with the type Int
, and it is assigned the value of 5
. Since x
is a val
, its value cannot be changed later in the program.
