What application to write to demonstrate the operation of synchronization?

Question

Java

Hey! I would like to know how it would be better to write an application that demonstrates how synchronization works?
I thought about making a program that would write to two streams in different files and I don’t understand how to synchronize them with each other?
Apply a hash and compare them on each of the write operations?
Or maybe choose a different concept of the application altogether?

Read a textbook on the basics of system programming, at least the same Pobegailo.
