问题

以下是已经翻译好的内容：

public abstract class RepoSearchResult {
    public static class Success extends RepoSearchResult {
        // 在这里添加必要的属性和方法
    }
    public static class Error extends RepoSearchResult {
        // 在这里添加必要的属性和方法
    }
}

英文:

How to convert this Kotlin class to Java

sealed class RepoSearchResult {
    data class Success(val data: List&lt;Repo&gt;) : RepoSearchResult()
    data class Error(val error: Exception) : RepoSearchResult()
}

<sup>code source: github</sup>

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 {

    }
}

使用IntelliJ将该类反编译为Java产生以下结果。我将Repo更改为String，以便在本地编译时不需要依赖项。

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