从 WSL 完全卸载 openjdk-11

Question

我是 Python 程序员，但想在项目中使用 Java/Scala（所以学习 Java/Scala）。

在我的 Windows 子系统 Linux (WSL) 中，我之前安装了 OpenJDK v 11。我想用较低版本或 Java 8 替换 OpenJdk 11.0.07，因为我运行的程序之一需要 Java 8。

当我查看 Window 的控制面板时，我没有看到 java（我的意思是我手动从控制面板中删除了），很明显，命令提示符说没有安装 Java。但是当我在 WSL 中发出命令时：

java --version

我得到以下结果：

openjdk 11.0.7 2020-04-14
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.7+10)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.7+10, mixed mode)

如何删除上述内容并在 ubuntu (WSL) 和 Windows 中安装 openjdk 8。

我玩过的一个命令是：sudo apt-get remove openjdk*

sudo apt-get remove openjdk*

Wsl 是 Windows 内核上的 Linux 系统。您应该使用与安装 JVM 相同的 Linux 工具来卸载 JVM。

对于 Ubuntu，这通常是 apt 或 dpkg

如果您想完全重新开始，请删除该应用并重新安装。
