title: How to create real static property in kotlin
body: <p>I hava an A.java file ->
  <code>class A{ public static Integer age = 30;}</code> </p>
  
  <p>and hava a B.java file -> <code>print(A.age)</code></p>
  
  <p>but when I convert A.java to A.kt it does't work by <strong>object</strong> or <strong>companion</strong> keyworld.</p>
  
  <p>if I use <strong>object</strong> I must change it to <code>print(A.INSTANCE.age)</code>
  and if I use <strong>companion</strong> I must change it to <code>print(A.Companion.age)</code> , but I can't change B.java file in some condition , So what can I do for it? </p>
