The thing that's fun about these tasks is knowing that we've largely obsoleted a lot of the previous tasks where we had to tediously parse files to identify and assign variables. Properties & Serializable FTW!

Even these "easy" tasks are not easy because there's not much understanding, at least in my case.

Hint: pay attention to the order of the objects in writeExternal and readExternal methods.

In "Externalizable Person": The readline() method is deprecated, so use read/writeUTF() instead

or try <variableName> = (<variableType>) in.readObject(); worked for me

"Externalizable Person" hint: do not read/write any lines, that messes up the whole saving/loading process. Only objects and ints.
