Q1. How to make singleton class thread safe?
Ans. 
To make a singleton class thread safe, we can use synchronized keyword or double-checked locking.
• Use synchronized keyword to ensure only one thread can access the instance at a time.

• Use double-checked locking to minimize the use of synchronization.

• Use volatile keyword to ensure visibility of changes across threads.

• Consider using an enum to implement singleton pattern as it is inherently thread safe.
