Answer:
True
Explanation:
A final class is something like sealed one and no one can inherit that further.
it is useful to lock our code or functionality from others
Solution:
The process of transaction can guarantee the reliability of business applications. Locking resources is widely used in distributed transaction management (e.g; two phase commit, 2PC) to keep the system consistent. The locking mechanism, however, potentially results in various deadlocks. In service oriented architecture, the deadlock problem becomes even worse because multiple transactions try to lock shared resources in the unexpectable way due to the more randomicity of transaction requests, which has not been solved by existing research results. In this paper, we investigate how to prevent local deadlocks, caused by the resource competition among multiple sub-transactions of a gl obal transaction, and global deadlocks from the competition among different global transactions. We propose a replication based approach to avoid the local deadlocks, and a timestamp based approach to significantly mitigate the global deadlocks. A general algorithm is designed for both local and global deadlock prevention. The experimental results demonstrate the effectiveness and efficiency of our deadlock prevention approach. Further, it is also proved that our approach provides higher system performance than traditional resource allocation schemes.
This is the required answer.
Option B is the correct answer, Employers have flexibility in choosing a fall protection system they believe will work best in a situation selected. It is the primary duty of employer to provide safety to its workers. Employers must setup a suitable protection system at workplace from falling off from overhead platforms and from elevated workstations during construction for safety of its employees.
Further Explanation:
⦁ Employer must ensure compliance to OSHA-Fall protection in construction.
⦁ Generally, fall protection must be ensured by deploying guardrail systems at the edge of construction sites, safety systems built by nets or personal fall arrest.
⦁ OSHA requires to built fall protection system irrespective of fall distance to make sure safety conditions for workers/ employees.
