Variables in Kotlin, differences with Java: 'var' vs. 'val'?

Question

I am trying to learn Kotlin. What is val, var and internal in Kotlin compared to Java?

In Java:

 RadioGroup radio         


        

Answer 1

val use to declare final variable. Characteristics of val variables

1. Must be initialized
2. value can not be changed or reassign

var is as a general variable

3. We can initialize later by using lateinit modifier

   [lateinit also use for global variable we can not use it for local variable]

4. value can be changed or reassign but not in global scope

val in kotlin is like final keyword in java
