Millised mehhanismid kasutatakse RxJava-s täitmisvoogude vahetamise haldamiseks?

In RxJava, the operators subscribeOn() and observeOn() are used to manage execution threads.

• subscribeOn() determines on which thread the subscription and execution of the original Observable will occur. It is usually used to specify a background thread, for example, Schedulers.io() for input/output operations.

• observeOn() switches the thread on which subsequent operators and final subscribers will process. For example, you can switch to the main Android thread using AndroidSchedulers.mainThread().

Example:

Observable.just("data")
    .subscribeOn(Schedulers.io())          // execution on background thread
    .observeOn(AndroidSchedulers.mainThread()) // processing result on UI thread
    .subscribe(data -> {
        // update UI
    });

Thus, subscribeOn sets the thread for the data source, and observeOn for processing the results.
