$ brew install --cask adoptopenjdk11
$ brew install --cask adoptopenjdk14- 17버전을 설치하고 싶으면
$ brew install --formulae openjdk@17을 입력하면된다.

$ sudo vim ~/.zshrc

# Java 14
# export JAVA_HOME=$JAVA_HOME_14자바 버전을 바꾸고 싶을때는 11버전을 주석처리하고 14버전 주석을 풀어주면 된다.
- 17버전은 경로가 다르기 때문에
export JAVA_HOME_17 = JAVA_HOME=/opt/homebrew/Cellar/openjdk@17/17.0.5/libexec/openjdk.jdk/Contents/Home를 넣어줘야 한다. (버전은 다를수 있음)
그 다음 source ~/.zshrc 또는 터미널을 재실행하여 변경내용을 적용해준다.
