java9系列(二)docker运行java9

序

本文介绍下如何在docker运行java9

镜像

docker pull openjdk:9-jdk

启动

docker run -it openjdk:9-jdk /bin/jshell

然后就可以正常使用jshell了，比如

Sep 22, 2017 2:16:12 AM java.util.prefs.FileSystemPreferences$1 run
INFO: Created user preferences directory.
|  Welcome to JShell -- Version 9-Debian
|  For an introduction type: /help intro

jshell> Arrays.asList(1,2,3,4).stream().limit(3).forEach(e -> System.out.print(e))
123

退出

jshell> /exit
|  Goodbye
