我按照wiki安装java 测试过程出错 有提示 请高手看 指教

[boyzhigang]

root@ubuntulgy:~# sudo update-alternatives --config java

There are 3 alternatives which provide `java'.

Selection Alternative
-----------------------------------------------
1 /usr/bin/gij-wrapper-4.1
+ 2 /usr/lib/jvm/java-gcj/jre/bin/java
* 3 /usr/lib/jvm/java-1.5.0-sun/jre/bin/java

Press enter to keep the default[*], or type selection number: 3
Using `/usr/lib/jvm/java-1.5.0-sun/jre/bin/java' to provide `java'.

root@ubuntulgy:~# javac HelloWorld.java
bash: javac: command not found
root@ubuntulgy:~# javac HelloWorld.java
bash: javac: command not found
root@ubuntulgy:~#

另外 java-1.5.0-sun-1.5.0.06 这个文件夹 是空的
