Convert Kotlin class to Java

How to convert this Kotlin class to Java

sealed class RepoSearchResult {
    data class Success(val data: List<Repo>) : RepoSearchResult()
    data class Error(val error: Exception) : RepoSearchResult()
}

^{code source: github}

I created this but I don't know if it's correct, and if it is how to return data from it?

public abstract class RepoSearchResult {
    public static class Success extends RepoSearchResult {

    }
    public static class Error extends RepoSearchResult {

    }
}

Decompiling that class to Java with IntelliJ produces this. I changed Repo to String so that it would compile locally without dependencies.
