jdk

I finished some steps of installation of jdk-7u1 in Ubuntu 1.11 until below steps. after that step the terminal tells that there is nothing to configure. after that when I run a java file the terminal said that usr/lib/jvm/java : no such a file or directory.

 sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.7.0/bin/java" 1
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.7.0/bin/javac" 1
sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.7
