HashMap 放在一个循环中

Question

for (int i = 0; i < projectList.size(); i++) {
        String projectName = projectList.get(i);
        String url = "https://api.github.com/repos/apache/" + projectName + "/commits";

        try {
            data = Jsoup.connect(url).timeout(30000).ignoreContentType(true).execute().body();
            System.out.println(url);
            // System.out.println(data);

        } catch (Exception e) {
            e.printStackTrace();
        }
        objArray = new JSONArray(data);

        for (int i1 = 0; i1 < objArray.length(); i1++) {
            obj = objArray.getJSONObject(i1);               

            if (!obj.isNull("committer")) {
                obj1 = obj.getJSONObject("committer");
                commiterName = obj1.getString("login");
            }
            else {
                continue;
            }
            if (!UserCommitCount.containsKey(commiterName)) {
                UserCommitCount.put(commiterName, 1);
            } else {
                UserCommitCount.put(commiterName, UserCommitCount.get(commiterName) + 1);
            }

        }
        UserCommitCount = sortByComparator(UserCommitCount, DESC);
        UserCommitCount = resizeUserCommitCount(UserCommitCount);
        printHashMap(UserCommitCount);
        System.out.println(projectName + "!!!!");
        printHashMap(UserCommitCount);

        RepoNameCommitterMap.put(projectName, UserCommitCount);
        UserCommitCount.clear();
        System.out.println(projectName+ "AFTER");
        printHashMap(UserCommitCount);
        printNestedHashMap(RepoNameCommitterMap);
    }

所以我试图将数据存储在 Hashmap 中，输出是这样的

https://api.github.com/repos/apache/zookeeper/commits

hanm - 4

anmolnar - 23

lvfangmin - 3

zookeeper!!!!

hanm - 4

zookeeper - {}

然后继续。您会看到在第一个 put 命令中放置了键，但 hashMap 没有放置，它会移动下一次迭代。我不明白为什么会这样。谁能帮我修一下？

在第一次迭代 ReponameCommiter.put 中，放置 repo 的名称但不放置 userCommitCount Map。

Answer 1

您正在打印两次哈希映射：

printHashMap(UserCommitCount);
System.out.println(projectName + "!!!!");
printHashMap(UserCommitCount);

也许您应该只打印一次？
