扩充映射<；长字符串>；值导致java.lang.ClassCastException：java.lang.Integer不能转换为java.lang.Long

我正在开发一个web应用程序，它要求对给定GitHub用户在所有存储库中使用的语言进行排序，从使用最多的语言到使用最少的语言。作为此过程的一部分，我将执行以下操作：

CreateNewUser.java

            //store a mapping of languages to bytes written in that language
            Map<String, Long> allLangs = new HashMap<>();

            //get all repositories for the user
            Map<String, GHRepository> repositories = github.getMyself().getRepositories();

            //loop through each repository
            for (String repo : repositories.keySet()) {

                //get languages specific to repository mapped to bytes written in languages
                Map<String, Long> languages = repositories.get(repo).listLanguages();

                //loop through languages in repository
                for (String lang : languages.keySet()) {

                    //if the global language map contains the key
                    if (allLangs.containsKey(lang)) {
                        //add the value for this repository to the total bytes written
//**exception is thrown here**
                        allLangs.replace(lang, languages.get(lang) + allLangs.get(lang)); //line 73
                    } else {
                        //just add the number of bytes written
                        allLangs.put(lang, languages.get(lang));
                    }
                }
            }

我已尝试使用多种方法将标记为

/**异常的行上的值
languages.get（lang）+allLangs.get（lang）
转换为
Long
，但没有成功。有什么想法吗？
好吧，您似乎已经在
映射中存储了
整数
值，您正试图将其用作
长
s。谢谢@SotiriosDelimanolis，您是对的。我检查了我正在使用的GitHub API Java库的源代码，并修复了这个问题。
