1.終端中檢視當前系統JAVA版本

java -version
java version "1.8.0"

3.安裝JENV

brew install jenv

echo 'export PATH="$HOME/.jenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(jenv init -)"' >> ~/.bash_profile

jenv add /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
jenv add /Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home

$ jenv versions
* system (set by /Users/su/.jenv/version)
  1.6
  1.6.0.65
  1.8
  1.8.0
  oracle64-1.6.0.65
  oracle64-1.8.0
 

jenv local oracle64-1.6.0.65

java -version
java version "1.6.0_65"
