<p dir="auto">直近のjapaneseの投稿から今回は結果を拾いましたので、漏れているSteemianの皆様も多いと思います。
<p dir="auto">レビュテーションの計算は、Githubで公開されている<a href="https://ja.wikipedia.org/wiki/Python" target="_blank" rel="noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">Pythonの計算式をJavaに置き換えてみました。
<pre><code>List<AccountReputation> accountReputation = steemJ.getAccountReputations(accountName, 1);
long raw = accountReputation.get(0).getReputation();
String rawStr = String.valueOf(raw);
boolean neg = rawStr.charAt(0) == '-' ? true : false;
rawStr = neg ? rawStr.substring(1) : rawStr;
double out = Math.log10(Long.parseLong(rawStr));
if (out == Double.NaN) out = 0;
out = Math.max(out - 9, 0);
out = (neg ? -1 : 1) * out;
out = out * 9 + 25;
repInt = (int) out;
<p dir="auto">トライアンドエラーで色々と遊んでいるので、ソースは汚いのですが、まずはこれで動作させました。
<p dir="auto">DiscussionQueryの仕様で最大100件までしか一度に取得できませんので、取得できてないSteemianの方もいます。全て取得するには何かしら工夫が入りますね。

どうしても習得できなかったJava。クラスとか意味が分からなかったです。JavaScriptは全く別物ですぐ理解できたんですけどねー。
Javaはバージョンが上がって習得しづらいくなってしましました。Javaは慣れ親しんでるので抵抗はあまりないんですが、JavaScriptは逆に習得しづらいです。どちらもよくつかわれるので頑張ってキャッチアップしています!
私はC言語やアセンブラで育ったので、Javaは理解しがたかったです。
C言語やアセンブラのほうが難易度高いですよね笑。またちょっと面白いプログラム書いてみます!
より、機械よりの言語だからね😅
