What is the purpose of Collections.syncronizedList() method?

To make the list thread-safe
To sort the list
To shuffle the list elements
To reverse the list order

The correct answer is: To make the list thread-safe

Collections.syncronizedList() method is used to make a list thread-safe, or to ensure that the list can be accessed and modified by multiple threads without causing errors or inconsistency in data. Options B, C, and D are incorrect as they involve manipulating the list in a different way, rather than making it thread-safe. Sorting, shuffling, and reversing the list order may not prevent errors or inconsistencies when it is accessed and modified by multiple threads. Therefore, it is important to use Collections.syncronizedList() method in such cases.
