What is the purpose of the synchronized keyword in Java?

The synchronized keyword in Java is used to restrict multiple threads from accessing shared resources simultaneously. By doing so, it prevents data inconsistencies and thread interference. This is achieved by locking the object, allowing only one thread to execute the synchronized block at a time.
