I would like to know the difference between 同一 and 同じ. They both mean 'the
same'.

Please feel free to provide example sentences so I can see clearly the
difference.

Difference between 同一 and 同じ?
The conclusion is practically same with [this
post](https://japanese.stackexchange.com/q/41802/7810), which @l'électeur has
linked. These two words have the same meaning except that 同じ is like _same_
and 同一 is like _identical_. 同一 is just another way to say 同じ in a more
bookish, formal, or rigid manner, unless otherwise defined.

Note that some fixed expressions such as 同一人物 may not sound overly formal, and
could be used in quite casual talks to mean "(identified as) the same guy".
