如果你想使用Java 10之外的AdoptOpenJDK发行版，你可以使用AdoptOpenJDK网站上描述的官方存储库(也适用于Debian):

Import the official AdoptOpenJDK GPG key by running the following command: wget -qO - https://adoptopenjdk.jfrog.io/adoptopenjdk/api/gpg/key/public | sudo apt-key add - Import the AdoptOpenJDK DEB repository by running the following command: sudo add-apt-repository --yes https://adoptopenjdk.jfrog.io/adoptopenjdk/deb/ If you get a command not found error, try running: apt-get install -y software-properties-common Then repeat the first command. Refresh your package list with apt-get update and then install your chosen AdoptOpenJDK package. For example, to install OpenJDK 8 with the HotSpot VM, run: apt-get install <adoptopenjdk-8-hotspot>

您可以在https://adoptopenjdk.jfrog.io/adoptopenjdk/deb/pool/main/a/下找到可用的软件包名称/ Java版本

参考问Ubuntu问题如何设置OpenJDK的JAVA_HOME ?，

如何在Ubuntu (Linux)下安装Open JDK (Java开发工具包)?

Open Terminal from Application Dash or press Ctrl+Alt+T Update repository: sudo add-apt-repository ppa:openjdk-r/ppa # only Ubuntu 17.4 and earlier sudo apt update Optional: To search available distributions of openjdk, use the following command: apt search openjdk Install the appropriate version with the following command: sudo apt install openjdk-8-jdk sudo apt install openjdk-8-source #this is optional, the jdk source code For JAVA_HOME (Environment Variable) type command as shown below, in "Terminal" using your installation path... export JAVA_HOME=/usr/lib/jvm/java-8-openjdk (Note: /usr/lib/jvm/java-8-openjdk is symbolically used here just for demostration. You should use your path as per your installation.) For PATH (Environment Variable) type command as shown below, in Terminal: export PATH=$PATH:$JAVA_HOME/bin To check your installation: java -version

你可以通过apt-get安装:

sudo add-apt-repository ppa:linuxuprising/java
sudo apt-get update
sudo apt-get install oracle-java11-installer

之后，不要忘记检查版本:

java -version

你可以用oraji。它可以从oracle java (.tar.gz)安装/卸载JDK或JRE。

执行sudo oraji '/path/ To /the/jdk_or_jre_archive' 如果需要卸载，请执行oraji -u命令并确认版本号。

如果您已经下载了ZIP文件，请遵循以下步骤。

运行以下命令解压缩文件。

tar -xvf ~/Downloads/jdk-7u3-linux-i586.tar.gz
sudo mkdir -p /usr/lib/jvm/jdk1.7.0
sudo mv jdk1.7.0_03/* /usr/lib/jvm/jdk1.7.0/
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.7.0/bin/java" 1
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.7.0/bin/javac" 1
sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.7.0/bin/javaws" 1

安装完成后，请按照如下操作设置环境变量。

在/etc/profile文件中编辑系统路径:

sudo gedit /etc/profile

在末尾添加以下几行。

JAVA_HOME=/usr/lib/jvm/jdk1.7.0
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
export JAVA_HOME
export PATH

步骤01:下载JDK

从oracle官方网站下载JDK版本: [Oracle网站下载JDK]: https://www.oracle.com/in/java/technologies/javase-downloads.html

 e.i - jdk-11.0.12_linux-x64_bin.tar.gz

步骤02:安装:

a)使用以下命令解压下载的文件

sudo -tar -vzxf jdk-11.0.12_linux-x64_bin.tar.gz

b)在usr/lib目录下创建一个名为java的目录

mkdir java

c)将解压后的jdk-11.0.12目录移动到新创建的目录java中

sudo mv jdk-11.0.12 /usr/lib/java

03步:

a)依次执行以下命令

sudo update-alternative -install /usr/lib/java java /usr/lib/java/jdk-11.0.12/bin/java 1

sudo update-alternative -install /usr/lib/javac javac /usr/lib/java/jdk-11.0.12/bin/javac 1

步骤04:安装验证:

使用以下命令验证安装结果

 java --version
 javac --version
