What consequences can be expected after merging two execution threads?

Merging two threads usually means that one thread waits for the other to finish (for example, via the join method). The consequences of such merging are:

• Synchronization: The thread that initiated the merge is blocked until the other thread completes.
• Completion guarantee: After merging, it can be assured that the second thread has fully finished its work.
• State update: If the second thread modified shared data, it can be safely used after merging, as its work is complete.
• Race condition avoidance: Merging helps prevent race conditions by ensuring sequential execution.

In practice, for example in Android, thread merging is used for proper termination of background tasks before updating the UI or releasing resources.
