class

[Ninjakreborn]

What happens in the following scenario.
For instance if I want to create a parent class, and assign it a child, and a grandchild class. I decide that I want to create for instance a specific class, and I set it to final. If someone tries to change that variable in that class later it comes up with a fatal error, but couldn't the person just jump the the parent class anyway and change it from final to public with just a little typing, if this is true what is the purpose of setting it to final when it can still be changed.
