jdk1.8.0_211_linux_x64.rar
Java开发工具包（Java Development Kit，简称JDK）是Java编程语言的软件开发工具包，它是Java程序员编写、编译、调试和运行Java应用程序所需的所有工具的集合。JDK1.8.0_211是Oracle公司发布的一个特定版本，针对Linux x64平台优化。这个版本包含了Java运行时环境（JRE）、Java编译器（javac）、Java文档生成器（javadoc）、Java调试器（jdb）以及其他必要的工具。
在Ubuntu系统中安装JDK1.8.0_211有助于开发者快速搭建Java开发环境。Oracle官网上的下载通常需要注册并可能涉及版权条款，因此提供这个压缩包可以省去这些步骤，直接进行安装。
以下是安装和使用JDK1.8.0_211在Ubuntu上的详细步骤：
1. **解压文件**：你需要将"jdk1.8.0_211"这个压缩文件解压到一个合适的目录，例如`/usr/lib/jvm`。可以使用`unrar`或`tar`命令来完成解压操作。
```bash
sudo apt-get install unrar
unrar x jdk1.8.0_211_linux_x64.rar /usr/lib/jvm/
```
2. **设置环境变量**：为了让系统能够识别新安装的JDK，需要更新`JAVA_HOME`、`PATH`和`JRE_HOME`环境变量。
```bash
echo "export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_211" | sudo tee -a /etc/environment
echo "export JRE_HOME=$JAVA_HOME/jre" | sudo tee -a /etc/environment
echo "export PATH=$JAVA_HOME/bin:$PATH" | sudo tee -a /etc/environment
```
3. **使环境变量生效**：执行以下命令使修改后的环境变量立即生效。
```bash
source /etc/environment
```
4. **验证安装**：安装完成后，可以通过`java -version`和`javac -version`命令检查Java是否已正确安装。
```bash
java -version
javac -version
```
5. **配置默认JDK**：如果你有多个JDK版本，可能需要设置默认版本。使用`update-alternatives`命令来管理Java链接。
```bash
sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.8.0_211/bin/java 1
sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.8.0_211/bin/javac 1
sudo update-alternatives --config java
sudo update-alternatives --config javac
```
6. **使用JDK**：现在你可以使用JDK1.8.0_211来编写、编译和运行Java程序了。例如，创建一个简单的`HelloWorld.java`文件，然后用`javac`编译，最后用`java`运行。
```bash
nano HelloWorld.java
# 在文件中输入：public class HelloWorld { public static void main(String[] args) { System.out.println("Hello, World!"); } }
javac HelloWorld.java
java HelloWorld
```
JDK1.8.0_211引入了一些重要的特性，比如Lambda表达式、函数式接口、Stream API、方法引用等，这些都极大地提升了Java的生产力和代码简洁性。此外，还优化了Java虚拟机（JVM），包括G1垃圾收集器的改进，使得Java应用在性能上有了显著提升。因此，对于开发和维护Java项目，JDK1.8.0_211是一个可靠的版本。
