Variables in Kolin Android Studio

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.
