### 写在最前 ###

本示例以 Azul Java8 和 Oracle Java8 为例，实现动态切换两个版本的 JDK8。

### 下载安装 ###

*  Azul ARM JDK：[www.azul.com/downloads/?…][www.azul.com_downloads]
    
    ![format_png][]
 *  Oracle X86 JDK: [www.oracle.com/java/techno…][www.oracle.com_java_techno]
    
    ![format_png 1][]

> 安装完成后，终端输入 `java -version` 查看当前 JDK 版本

openjdk version "1.8.0_362"
    OpenJDK Runtime Environment (Zulu 8.68.0.19-CA-macos-aarch64) (build 1.8.0_362-b08)
    OpenJDK 64-Bit Server VM (Zulu 8.68.0.19-CA-macos-aarch64) (build 25.362-b08, mixed mode)
    复制代码

### 配置环境 ###

#### 1. 编辑配置文件 ####

vim ~/.bash_profile
    复制代码

#### 2. 配置 JDK 信息 ####

# 配置JDK路径
    export AZUL_JAVA_8_HOME=/Library/Java/JavaVirtualMachines/zulu-8.jdk/Contents/Home
    export JAVA_8_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_361.jdk/Contents/Home
    
    CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:.
    
    # 设置默认JDK版本
    export JAVA_HOME=$AZUL_JAVA_8_HOME
    
    # 配置alias命令可以动态切换JDK版本  
    alias zual_jdk8="export JAVA_HOME=$AZUL_JAVA_8_HOME"
    alias jdk8="export JAVA_HOME=$JAVA_8_HOME"
    
    export JAVA_HOME
    export PATH
    export CLASSPATH
    复制代码

#### 3. 立即将配置文件生效 ####

source ~/.bash_profile
    复制代码

#### 4. 验证配置 ####

stive@StivedeMacBook-Pro ~ % zual_jdk8
    stive@StivedeMacBook-Pro ~ % java -version
    openjdk version "1.8.0_362"
    OpenJDK Runtime Environment (Zulu 8.68.0.19-CA-macos-aarch64) (build 1.8.0_362-b08)
    OpenJDK 64-Bit Server VM (Zulu 8.68.0.19-CA-macos-aarch64) (build 25.362-b08, mixed mode)
    
    stive@StivedeMacBook-Pro ~ % jdk8
    stive@StivedeMacBook-Pro ~ % java -version
    java version "1.8.0_361"
    Java(TM) SE Runtime Environment (build 1.8.0_361-b09)
    Java HotSpot(TM) 64-Bit Server VM (build 25.361-b09, mixed mode)
    复制代码

#### 5. 查看 JDK 路径 ####

echo $JAVA_HOME
    复制代码

### 卸载 JDK ###

#### 1. 查看安装的 JDK 版本 ####

cd /Library/Java/JavaVirtualMachines
    ls
    复制代码

#### 2. 卸载指定版本 ####

sudo rm -rf /Library/Java/JavaVirtualMachines/版本号
    
    # 例如
    sudo rm -rf /Library/Java/JavaVirtualMachines/zulu-8.jdk
    复制代码

#### 3. 删除运行路径和运行环境等 ####

$sudo rm -fr /Library/Internet/Plug-Ins/JavaAppletPlugin.plugin
    
    $sudo rm -fr /Library/PreferencesPanes/JavaControlPanel.prefPane
    
    $sudo rm -fr ~/Library/Application/Support/Java
