或者你也可以使用其他 jvm，例如：

答案3
为什么不直接去 java.sun.com 下载呢？您将获得一个二进制包装的 shell 脚本。将其复制到您想要安装的位置，例如 /usr/local/ 和。（假设文件名为 jdk-sun-1.6.bin）
cd /usr/local/sh jdk-sun-1.6.bin
它会要求您接受许可证并将整个 jdk 解压到 jdk-sun-1.6 目录中。现在，将您的 $PATH 编辑为 /usr/local/jdk-sun-1.6/bin。如果您想转到较新或较旧的版本，您可以删除 jdk-sun-1.6 或在它旁边安装另一个 jdk 并更改路径。
我更喜欢直接从 Sun 网站安装 JDK，而不是使用 apt 实用程序。它包含在一个地方，您可以完全控制。
