Comparing val to a final is wrong!

vars are mutable vals are read only; Yes val cannot be reassigned just like final variables from Java but they can return a different value over time, so saying that they are immutable is kind of wrong;

Consider the following

var a = 10
a = 11 //Works as expected

val b = 10
b = 11 //Cannot Reassign, as expected

So for so Good!

Now consider the following for vals

val d
  get() = System.currentTimeMillis()

println(d)
//Wait a millisecond
println(d) //Surprise!, the value of d will be different both times

Hence, vars can correspond to nonfinal variables from Java, but val aren’t exactly final variables either;

Although there are const in kotlin which can be like final, as they are compile time constants and don’t have a custom getter, but they only work on primitives
