如果您想使用特定版本的JAVA [JDK],您总是可以安装它,并将JAVA_HOME指向新安装的版本。您可以在系统中安装多个版本的java。您的环境变量应该指向您想要使用的Java版本。

您需要编辑bashrc并添加以下内容:

export JAVA_HOME=/usr/java/jdk1.8.0_251
export PATH=${PATH}:${JAVA_HOME}/bin

验证您的Java版本的安装路径(例如:/usr/java/jdk1.8.0_251)。

重新启动bash或启动新的shell。

英文:

If you want to use a specific version of JAVA [JDK ] you can always install install it and point the JAVA_HOME to the newly installed version. You can have multiple versions of java installed in your system. Your environment variable should point to the Java version that you want to use.

You need to edit bashrc and add the below :

export JAVA_HOME=/usr/java/jdk1.8.0_251
export PATH=${PATH}:${JAVA_HOME}/bin

Verify the installation path for your Java version (example : /usr/java/jdk1.8.0_251).

Restart your bash or start a new shell.
