You have to perform outside of the doc directory not an inside.
/opt/app $ ls
doc
/opt/app $ javadoc -d doc MyClass.java
It will generate documentation in the doc directory.
You can use echo command if you don’t want to write manually(vi editor).
You are getting permission issues because under /etc/ all main configuration files are located. So normal user cannot edit or change without sudo privileges.
There is only single file available /etc/hosts so after hosts file, not recommend to use slash(/).
sudo echo "127.0.0.1 www.google.com" >> /etc/hosts
If you want to switch into root user then you can do
sudo -i
If you are facing any issues again let me know. Try it.

Hello, @Prem
If wget command is not available then you can install it by yum or apt command. Check the OS Distro.
cat /etc/os-release
then choose package manager, it’s yum or apt:
sudo apt install wget -y
sudo yum install wget -y
Hello, @Prem
You not copied correctly. You just added the newly tar file name but not added content which is going to be added.
tar -cf /home/bob/python.tar /home/bob/reptile/snake/python
Format:
sudo tar -cf <new-tar-file-name> <content-of-the-path>
