Ultimate Threads And Concurrency Test - 53+ MCQs: Threads and Concurrency test: Evaluate Your Programming Skills with Concurrency Questions and Answers

1. What is the significance of the 'ThreadLocal' class in Java, and how is it used in concurrent programming?

To declare variables as constants.

To manage a pool of threads.

To store variables specific to each thread.

To execute operations in a separate thread.

2. What is the purpose of the 'Atomic' classes in Java, and how do they contribute to thread safety?

To execute atomic operations on threads.

To ensure that operations on variables are atomic, avoiding race conditions.

To synchronize multiple threads effectively.

To perform operations with a large execution time.

3. Explain the 'Fork-Join' framework in Java and how it facilitates parallelism in programming.

It is a mechanism for creating lightweight processes.

It is a framework for parallelizing recursive algorithms.

It is a method for avoiding race conditions.

It is a synchronization primitive for managing multiple threads.

4. What is a thread in concurrent programming?

A sequence of instructions executed independently.

A lightweight process that shares the same resources.

A section of code that runs in parallel.

A type of data structure.

5. What is a mutex in concurrent programming?

A mechanism for controlling thread execution order.

A synchronization primitive ensuring mutual exclusion.

A lightweight process.

A data structure for storing thread information.

6. What is the purpose of synchronization in concurrent programming?

To increase parallelism.

To avoid race conditions and ensure data consistency.

To simplify code execution.

To reduce the number of threads.

7. How can you implement a producer-consumer scenario in concurrent programming?

By using a single thread for both production and consumption.

By ensuring that producers and consumers run independently.

By avoiding the use of threads in a producer-consumer model.

By relying on a single shared resource for both producers and consumers.

8. What is the 'ThreadLocalRandom' class in Java, and how is it used in concurrent programming?

It provides a thread-safe random number generator.

It ensures that random numbers generated by threads are synchronized.

It allows threads to share random numbers without synchronization.

It is used to create random threads in a program.

9. Which programming languages commonly support multithreading?

Python

Java

HTML

10. What does the term 'deadlock' refer to in concurrency?

A situation where two or more threads are blocked indefinitely.

Efficient synchronization of threads.

Executing multiple threads simultaneously.

Optimal resource utilization.
