title: Kotlin: Java can't resolve Kotlin Symbol?
body: <p>I have a Kotlin Code just like the below, <code>SingleKotlin.instance</code> can be called by the other Kotlin files</p>
  
  <pre><code>class SingleKotlin private constructor(){
      companion object {
          val instance by lazy {
              SingleKotlin()
          }
      }
  
  }
  </code></pre>
  
  <p>However, when I try to call <code>SingleKotlin.instance</code> from java, it shows can't resolve symbol 'instance'</p>
  
  <p>I don't understand why, anybody can explian and how can I solve this problem?</p>
