Prerequisite: HomeBrew

Before we start

Find locations of previously installed Java JDK:

$ /usr/libexec/java_home -V
Matching Java Virtual Machines (1):
1.8.0_162, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_162.jdk/Contents/Home

Find the location of a specific Java version using -v:

$ /usr/libexec/java_home -v 1.8

Install with HomeBrew

  1. Update HomeBrew.
$ brew update

2. Add the casks tap.

$ brew tap homebrew/cask-versions

3. Install a specific version of the JDK such as java8, java10 or java for the current.

$ brew cask install java

Switching versions

Add the following aliases to .bash_profile.

export JAVA_8_HOME=$(/usr/libexec/java_home -v1.8)
export JAVA_11_HOME=$(/usr/libexec/java_home -v11)

alias java8='export JAVA_HOME=$JAVA_8_HOME'
alias java11='export JAVA_HOME=$JAVA_11_HOME'

# default to Java 11

Reload .bash_profile for the aliases to take effect.

$ source ~/.bash_profile

Use the alias to change version.

$ java8
$ java -version
java version "1.8.0_162"
Java(TM) SE Runtime Environment (build 1.8.0_162-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.162-b12, mixed mode)
