Java

この記事は約2分で読めます。

Javaは、1995年にSun Microsystemsにより初めてリリースされたプログラミング言語およびコンピューティング・プラットフォームです。Javaをインストールしないと機能しないアプリケーションやWebサイトが数多く存在し、さらに毎日作成されています。Javaは高速かつセキュアで、信頼性があります。ノートブックからデータセンター、ゲーム・コンソールから科学計算用スーパーコンピュータ、携帯電話からインターネットにいたるまでJavaはあらゆるところにあります。

引用元:java.com

Webアプリ、モバイルアプリ、Webサイト、ゲーム、などJavaはとにかく万能な言語です。
コンパイル語なので コンパイル を必要とした サーバーサイド言語 です。

オススメの エディター は「 eclipse 」です。

for文、if文などの基本文法が利用でき、特徴として全ての変数において「型宣言」が必要です。

開発イメージとしては、 MVCモデル が基本です。

ユーザー ➡︎ Controller(サーブレット) ➡︎ Model(Beansなど) ➡︎ データベース
データベース ➡︎ View(JSP) ➡︎ ユーザー

サーバーサイド言語でありながら、JSPファイルではHTML/CSSなど フロントサイド の構築も可能です。
