我目前在 PC 上运行的是 Ubuntu GNOME 16.10,但不幸的是,我没有互联网连接。我真的非常需要能够在其上运行 Java 程序,因为我已经开始学习 Java。我的手机有互联网连接。有没有什么方法可以在没有互联网连接的情况下将 Java 下载到手机上,然后手动将其安装在 PC 上?
答案1
从 ORACLE 网站下载 java SE(zip 或 tgz),找到一种方法将打包的文件放在 Ubuntu 机器上,然后解压它。
假设你在 /opt/jdk_xyz 解压
然后在你的主目录中的 .bashrc 文件中添加以下内容
导出JAVA_HOME=/opt/jdk_xyz 导出PATH=$PATH:$JAVA_HOME/bin
答案2
这是什么类型的手机?您应该能够在手机上设置热点并将其连接到计算机。

使用以下命令下载 Java SE 开发工具包:

提取文件:
tar -xvzf jdk-8u131-linux-x64.tar.gz
更改目录:
cd jdk1.8.0_131/
更新替代方案:
sudo update-alternatives --install /usr/bin/java java /opt/java/jdk1.8.0_45/bin/java 100 && sudo update-alternatives --config java && sudo update-alternatives --install /usr/bin/javac javac /opt/java/jdk1.8.0_45/bin/javac 100 && update-alternatives --config javac && sudo update-alternatives --install /usr/bin/jar jar /opt/java/jdk1.8.0_45/bin/jar 100 && sudo update-alternatives --config jar
设置环境变量:
sudo export JAVA_HOME=/opt/java/jdk1.8.0_131/ && sudo export JRE_HOME=/opt/java/jdk1.8.0_131/jre && sudo export PATH=$PATH:/opt/java/jdk1.8.0_131/bin:/opt/java/jdk1.8.0_131/jre/bin
- 或者更好的方法是全局设置环境变量:
- 编辑
/etc/environment
并添加以下行:JAVA_HOME=/opt/java/jdk1.8.0_131/
JRE_HOME=/opt/java/jdk1.8.0_131/jre
PATH=$PATH:/opt/java/jdk1.8.0_131/bin:/opt/java/jdk1.8.0_131/jre/bin
- 重新启动系统。
