Answer 1

You could just use a single thread, of course.

You can design your application to avoid sharing mutable state, so that methods are inherently threadsafe.

You can use synchronized library collections.

You can use threadsafe queues to communicate between threads (Concurrent Queues).

It rather depends on what you are trying to achieve...
