我正试图开始使用java,但到目前为止还不能在我的机器上正确地使用它。我非常希望能够从命令行编译。按照指示操作后

here

没有错误,我无法编译

javac

. 以下是我目前掌握的情况:

当我进入时:

$ 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)

当我跑步的时候:

$ sudo apt-get install sun-java6-jdk
