Câu trả lời

The term "synchronized" in Java refers to the capability to control the access of multiple threads to any shared resource. It is used to ensure that only one thread can access a critical section of code at a given point in time, preventing interference and inconsistencies that may arise due to concurrent access[1][3].

Synchronization in Java can be achieved through various mechanisms, such as synchronized methods and synchronized blocks. A synchronized method is a method that is locked for any shared resource, ensuring that only one thread can invoke it at a time[1][3]. On the other hand, a synchronized block is a section of code within a method that is locked for a specific resource, allowing for more fine-grained control over synchronization[5].

Synchronization is essential in Java to ensure thread safety and prevent data inconsistencies in a multi-threaded environment. It is particularly useful in scenarios where multiple threads need to access and modify shared resources concurrently. By using synchronization, developers can ensure that these shared resources are accessed in a controlled and predictable manner, avoiding issues such as race conditions and data corruption[1][3][5].

In summary, synchronized in Java is a mechanism that allows developers to control the access of multiple threads to any shared r...
