Java18がほしいので、下記コマンドでインストール
$ sdk install java 18-open
インストールが終わったら、バージョン確認
$ java -version openjdk version "18" 2022-03-22 OpenJDK Runtime Environment (build 18+36-2087) OpenJDK 64-Bit Server VM (build 18+36-2087, mixed mode, sharing) $ javac -version javac 18
環境構築完了！！！！！！！！！！
雑記
sdkmanのおかげで、バージョンアップがだいぶ楽になったな。。。
