Variables in Kolin Android Studio

Declaring of Variables in Kotlin using Android Studio: 

 val is used to declare a variable in Kotlin

val is immutable i.e. it cannot be reassigned after it is declared.

Method 1:
val name: String

val number: int

val number: float

val number: double

val state: boolean

Now declaring values for variables

name="Tech Uplift"

number= 1

number= 1.006

number= 1.5

state=false

In the method  above variables are explicitly declared .Saying that the type of variable should be declared first.

Method 2:
In this method variables are not declared explicitly.
They are straight way declared.

val name="Tech Uplift"

val number= 1

val number= 1.006

val number= 1.5

val state=false

Similarly var can be used
but var is mutable
can be changed even after it is declared.
