19. Variables in Scala

20. Mutable Variable
• Mutable variables are defined by using the var keyword.
• It allows you to change value after declaration of variable.
Eg:
var data = 100 var data:Int = 100
data = 101

21. Immutable Variable
• These variables do not allow you to change a value after the declaration of a
variable.
• Immutable variables are defined by using the val keyword.
• Eg:
var data = 100 Output: Error: reassignment to val
data = 101
