2. Close Firefox browser and run the following command. Don’t forget to run it with normal user permission, not with root permission user. Do not forget to adjust the name of the Java binary installer in accordance with the the file you’ve downloaded on earlier task.
   01.sudo mkdir -p -v /opt/java/64

   02.tar -zxvf jre-7u7-linux-x64.tar.gz
