What methods can be used to eliminate race conditions in multithreaded programming?

To eliminate race conditions in multithreaded programming in Java, the following methods are used:

• Synchronization (synchronized): blocks access to critical sections of code, allowing only one thread to execute them.

• Using classes from java.util.concurrent: for example, ReentrantLock, Semaphore, CountDownLatch for more flexible thread management.

• Atomic operations: classes from the java.util.concurrent.atomic package (e.g., AtomicInteger) allow operations to be performed without locks.

• Avoiding shared access: designing thread-safe data structures or using immutable objects.

Example of using synchronized:

public class Counter {
    private int count = 0;

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

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

This approach prevents multiple threads from simultaneously modifying the count variable, eliminating race conditions.
