Not really. But what you can do is to install Java on one computer and then ZIP the folder where the files were installed. To install on all the other computers, just unzip the archive, set JAVA_HOMEand change the PATHvariable.
并不真地。但是您可以做的是在一台计算机上安装 Java，然后压缩安装文件的文件夹。要在所有其他计算机上安装，只需解压缩存档，设置JAVA_HOME并更改PATH变量。
If that's too much work to do manually, you can try to create a custom installer.
如果手动完成太多工作，您可以尝试创建自定义安装程序。
Note that this might violate the EULA; if you do this for a company, have legal check this.
请注意，这可能违反 EULA；如果您为公司这样做，请进行法律检查。

You can't do this from the command line for Oracle's JDK as you must accept their license agreement on their web site before you can download.
您不能从 Oracle JDK 的命令行执行此操作，因为您必须在其网站上接受他们的许可协议才能下载。
You could download and install the latest OpenJDK using wgetand run the installer. (two commands) You would need to change your environment settings which might be possible using a command line regedit, but I always use the windows configuration for this.
您可以使用wget并运行安装程序下载并安装最新的 OpenJDK 。（两个命令）您可能需要使用命令行 regedit 更改您的环境设置，但我总是为此使用 Windows 配置。
