#安装sdkman

curl -s "https://get.sdkman.io" | bash

source "$HOME/.sdkman/bin/sdkman-init.sh"

sdk version

正常出现sdkman版本号就安装成功了

#安装java

#安装java8

sdk install java 8.0.412.fx-zulu

建议和上述一样安装 fx-zulu 的jdk，这样会自带JAVAFX，方便后续使用java工具

ln -s ~/.sdkman/candidates/java/8.0.412.fx-zulu ~/.sdkman/candidates/java/8

sdk use java 8

java -version

#安装jdk11

sdk install java 11.0.23.fx-zulu

ln -s ~/.sdkman/candidates/java/11.0.23.fx-zulu ~/.sdkman/candidates/java/11

sdk use java 11

java -version

#安装jdk22

sdk install java 22.0.1.fx-zulu

ln -s ~/.sdkman/candidates/java/22.0.1.fx-zulu ~/.sdkman/candidates/java/22 

sdk use java 22                                                            

java -version
