0.000 HBD【Programming】Java Development vol.1 / SteemJを用いてJavaプログラムからSteem APIを実行する。
[Steem API](https://developers.steem.io/)には[JavaScript](https://ja.wikipedia.org/wiki/JavaScript)や[Python](https://ja.wikipedia.org/wiki/Python)、[Java](https://ja.wikipedia.org/wiki/Java)から呼び出すためのライブラリが公開されています。今回JavaプログラムからSteem APIを実行し、各種情報を表示したいと思います。 まず、以下のページに行き、JavaからSteem APIを呼び出すための[SteemJ](https://github.com/marvin-we/steem-java-api-wrapper/wiki/How-to-add-SteemJ-to-your-project)と呼ばれるライブラリをクローンします。 https://github.com/marvin-we/steem-java-api-wrapper  クローンしたプロジェクトを[統合開発環境(IDE)](https://ja.wikipedia.org/wiki/%E7%B5%B1%E5%90%88%E9%96%8B%E7%99%BA%E7%92%B0%E5%A2%83)で開きます。ここでは[IntelliJ IDEA](https://ja.wikipedia.org/wiki/IntelliJ_IDEA)としてプロジェクトを動作させたいと思います。 クローンしたプロジェクトを開きます。  プロジェクトをビルドします。  my.sample.project.SteemJUsageExample.javaを参考にし、アカウント名とプライベートキーをソースに記述します。  ##### ※赤枠の箇所を各自のアカウント情報に書き換えます。 試しに[promari](https://steemit.com/@promari)のアカウントからフォロー情報を取得してみましょう。  コンソールにアカウントのフォロワー情報が取得されています。  SteemJはJavaからsteem API実行するためのラッパーライブラリなので、これを使えばボットや各種集計などを手軽にツールとして実行することが可能です。 時間がありましたら色々とこのSteemJを使ってSteemをいじくり倒してみたいと思います。  written by [tamito0201](https://steemit.com/@tamito0201/) プログラミングとのご縁結びなら[プロマリ](https://www.programming-mariage.jp/)へ。 オンラインプログラミング学習スクールの[プロマリ](https://www.programming-mariage.jp/)は、プログラミングの初学者の皆様を応援しています。プログラミング講師と一緒に面白いアプリを作りませんか。 <a href="https://www.programming-mariage.jp"></a> <a href="https://www.programming-mariage.jp/about"></a> The programming school "[Promari](https://www.programming-mariage.jp/)" will help you learn programming.
