如果JDK成功安装，则会在终端上显示JDK版本信息。
配置环境变量：
打开/etc/environment文件：
代码语言：javascript
复制
sudo nano /etc/environment在文件末尾添加以下行：
代码语言：javascript
复制
JAVA_HOME="/usr/lib/jvm/java-17-openjdk-amd64"
PATH=PATH:JAVA_HOME/bin这里假设您使用的是OpenJDK 17，如果您使用的是Oracle JDK，请将JAVA_HOME路径更改为相应的路径。
保存并关闭文件。
更新环境变量：
代码语言：javascript
复制
source /etc/environment检查环境变量是否正确配置：
代码语言：javascript
复制
echo $JAVA_HOME
echo $PATH如果环境变量已正确配置，则会在终端上显示JAVA_HOME和PATH的值。
以上步骤完成后，您就成功安装了JDK 17并配置了环境变量。
