The document discusses two types of variables in Scala: mutable and immutable. Mutable variables, defined with the 'var' keyword, allow value changes after initialization, while immutable variables, defined with the 'val' keyword, do not permit changes. This differentiation is likened to Java final variables.

❏ In Scala there are 2 types of variables
Mutable Variables (Read / Write):
❏ Mutable variables are the variables which allow us to change a value after the initializing a
variable.
❏ Mutable variables are defined by using the var keyword.
Immutable Variables (Read only) :
❏ Immutable variables are the variables which do not all us to change a value after the initializing a
variable.
❏ Immutable variables are defined by using the val keyword.
❏ Similar to Java Final variables.
