- Q18. Explain Synchronized keyword
- Ans.
Synchronized keyword is used in Java to control access to shared resources by multiple threads.
Synchronized keyword can be applied to methods or code blocks to ensure only one thread can access the synchronized code at a time.
It prevents race conditions and ensures thread safety by creating a lock on the object or class.
Example: synchronized void myMethod() { // synchronized code block }
- Q19. What are the consequences of excessively using synchronized blocks and methods in Java?
- Ans.
Excessive use of synchronized blocks and methods in Java can lead to performance issues and potential deadlocks.
Decreased performance due to increased contention for locks
Potential deadlocks if multiple threads are waiting for each other to release locks
Increased complexity and difficulty in debugging and maintaining code
Use synchronized sparingly and consider alternatives like ConcurrentHashMap or Lock interface
- Q20. How can you determine the number of threads needed for your application?
- Ans.
The number of threads needed for an application can be determined based on factors like the type of tasks, hardware resources, and performance requirements.
