In kotlin difference between var and val

In Kotlin difference between VAR and VAL

//https://abhiandroidknowledge.blogspot.com/2018/04/in-kotlin-difference-between-var-and-val.html

VAR : Var is mutable variable in Kotlin i.e var is read and write value. We can change value many times or assigned value in class.

Example:

var x = 25

//first inialised the value of x

print(x)

 x= 26

//change the value x in many times in class 

print(x)

   

VAL : Val is immutable in Kotlin i.e val is read only. Val is like final value in java. We can use val where I use final in java. Val is constant variable.

Example:

val x = 25

//first inialised the value of x

print(x)

//can not change the value of x because x is immutable
 x= 26

// compile time error Val cannot be reassigned
print(x)

Output:

Error : Kotlin:  Val cannot be reassigned
