linux - 让Java JDK在ubuntu上编译

Question

我正在尝试开始使用 Java，但到目前为止还无法在我的机器上正确安装它。我真的很想能够从命令行编译。按照说明进行操作后 here没有错误，我无法使用 javac 进行编译。这是我到目前为止所拥有的:

当我输入时:

$ java -version

我得到:

java version "1.6.0_16"  
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)  
Java HotSpot(TM) Server VM (build 14.2-b01, mixed mode)

当我运行时:

$ sudo apt-get install sun-java6-jdk

我得到:

~$ sudo apt-get install sun-java6-jdk

当我运行时:

$ /media/disk/School/java/hw1$ javac HelloWorldApp,java  </pre>

我得到:

 * java-gcj-compat-dev

 * sun-java5-jdk  
 * jikes-kaffe  
 * sun-java6-jdk  
Try: sudo apt-get install <selected package>  
bash: javac: command not found

当我尝试更新(使用 sudo apt-get update)时，我得到:

E: The method driver /usr/lib/apt/methods/https could not be found.

有没有人遇到过这个问题？提前致谢...

您可以通过键入以下命令在最新版本的 Ubuntu 上安装 JDK:

sudo apt-get install sun-java6-jdk

您可能会发现这比尝试手动设置更容易。
