Kuidas voog saab kontrolli objekti üle ja kuidas toimub selle haaramine mitme-kiudse keskkonna puhul?

In a multithreaded environment, a thread gains control over an object through synchronization mechanisms that ensure exclusive access to the resource. In Android (and in Java in general), keywords and classes such as synchronized, ReentrantLock, and others are used.

When a thread wants to access an object, it attempts to acquire the monitor (lock) of that object. If the monitor is free, the thread gains control and can perform operations on the object. If the monitor is occupied by another thread, the current thread is blocked and waits for it to be released.

Example using synchronized:

public class Counter {
    private int count = 0;

    public synchronized void increment() {
        count++;
    }

    public synchronized int getCount() {
        return count;
    }
}

Here, the methods increment and getCount are synchronized, which guarantees that only one thread at a time can execute these methods, preventing race conditions.

Therefore, capturing an object means acquiring the monitor (lock) on that object, which ensures thread-safe access to its state.
