一、 ：编译Java，Debian有话说

Debian以其稳稳当当性和灵活性著称。而Java作为一门编程语言，在Debian系统上的编译与运行，有一些独特的注意事项。今天我们就来深厚入探讨一下在Debian周围下编译Java时有哪些细节不能忽视。

二、 准备干活：JDK的安装与配置

先说说确保你已经安装了Java Development Kit 。在Debian系统上， 你能用以下命令安装JDK：

sudo apt update
sudo apt install default-jdk

安装完成后设置JAVA_HOME周围变量，方便后续操作：

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
export PATH=$JAVA_HOME/bin:$PATH

三、编译Java程序

编译Java程序非常轻巧松，只需用javac命令即可。

javac HelloWorld.java

如果编译成功，将在当前目录下生成一个名为HelloWorld.class的字节码文件。

四、 管理优良几个Java版本

如果你系统中安装了优良几个版本的Java，能用update-alternatives命令来管理不同版本的Java。

sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/java-11-openjdk-amd64/bin/java 1

五、glibc版本问题

当你需要编译需要特定版本glibc的项目时如果当前系统的glibc版本过矮小，就兴许出现编译错误。这时你需要升级glibc。

sudo apt-get install glibc-source
sudo apt-get install build-essential
sudo apt-get install libncurses5-dev
sudo apt-get install libssl-dev
