- 从这里下载最新的 JAVA 8 SE 开发工具包:https://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html
- 打开你的终端.
- 输入
$mkdir/opt/jdk. - 在新文件夹中解压 Java
$tar -zxf jdk-8u5-linux-x64.tar.gz -C/opt/jdk. - 通过运行这两条指令(或其他指令，取决于您的配置)，将 oracle JDK 设置为默认 JVM:
注意:每个项目符号都是一个命令
update-alternatives --install/usr/bin/java java/opt/jdk/jdk1.8.0_/bin/java 100 update-alternatives --install/usr/bin/javac javac/opt/jdk/jdk1.8.0_<YourVersion>/bin/javac 100
您可以通过运行 java -version 来检查结果！
You can check the result by running java -version !
