Scala is a statically-typed language, which means that variable types are declared at compile-time and cannot be changed during runtime. Once a variable is declared with a certain type, it can only hold values of that type or any subtypes.

Mutable variables are variables whose values can be changed after initialization. In Scala, mutable variables are declared using the var keyword. Here is an example:

var x: Int = 5 // declare a mutable variable of type Int and initialize it with 5
x = 10 // change the value of x to 10

Type casting in Scala is done using the asInstanceOf method, which converts a value from one type to another. Here is an example:

scala
val x: Any = "Hello"

Note that type casting should be used with caution, as it can lead to runtime errors if the value cannot be cast to the desired type.
