Ubuntu 18.04 Open jdk 11 설치

안녕하세요.

Ubuntu 18.04에 Java 11을 설치해보도록 하겠습니다.

• Ubuntu terminal

  $sudo apt install openjdk-11-jdk
  $java -version
  openjdk version "11.0.8" 2020-07-14
  OpenJDK Runtime Environment (build 11.0.8+10-post-Ubuntu-0ubuntu118.04.1)
  OpenJDK 64-Bit Server VM (build 11.0.8+10-post-Ubuntu-0ubuntu118.04.1, mixed mode, sharing)

• 아래와 같은 에러가 나면 시도해세요.

$sudo apt update

하고 다시 시도해보시기 바랍니다.

• 설치 확인

  $java -version

위 사진처럼 버전이 올바르게 표시된다면 설치 성공입니다.

감사합니다.
