Answer from AI

The keyword synchronized in Java is used to ensure thread safety when accessing shared resources. It locks an object or method so that only one thread can execute the code inside the synchronized block or method at a time. For example, when working with a shared counter, synchronized can be used to prevent race conditions:

public class Counter {
    private int count = 0;

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

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

Thus, synchronized helps prevent multiple threads from modifying data simultaneously.
