What methods can guarantee the adherence to the order of operations in multithreaded programming?

In Java, to guarantee the order of operations in a multithreaded environment, the following methods are used:

• Synchronization (synchronized) — blocks or methods that ensure mutual exclusion and visibility of changes between threads.
• Volatile variables — guarantee that reads and writes to the variable are visible to all threads in the correct order.
• Using classes from java.util.concurrent — such as Lock, Semaphore, CountDownLatch, CyclicBarrier for controlling order and thread coordination.
• Atomic operations (Atomic classes) — like AtomicInteger, which provide atomicity and visibility of changes.
• Using final and proper object initialization — for safe publication of objects between threads.

Example with synchronized for operation order guarantee:

class Counter {
    private int count = 0;

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

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

Here, methods are synchronized, ensuring that increment and read operations are performed sequentially and are visible to all threads.
