下载多个版本的JDK

https://www.oracle.com/java/technologies/downloads/#java11

解压到/usr/lib目录

我安装了3个版本JDK

/usr/lib/jdk1.8.0_281
/usr/lib/jdk-11.0.11
/usr/lib/jdk-17.0.6-10

分别注册环境

alternatives --install /usr/bin/java java /usr/lib/jdk1.8.0_281/bin/java 8
alternatives --install /usr/bin/java java /usr/lib/jdk-11.0.11/bin/java 11
alternatives --install /usr/bin/java java /usr/lib/jdk-17.0.6-10/bin/java 17

刷新配置

update-alternatives --config java
source /etc/profile    
java -version
