title: Does Kotlin have primitive types?
body: <p>Does Kotlin have primitive types?. When I declare the variable: <code>val myAge: Int = 18</code> then the <code>myAge</code> variable stores the actual values is <code>18</code> or stores the addresses of the objects in the memory?. If <code>Int</code> is primitive type then why we can use its method like <code>myAge.minus(10)</code>?</p>
