Java Consumer with Threads

This tutorial covers creating a consumer demo using threads in Java. It explains how to set up a consumer thread class, implement consumer logic with a latch and loop, handle exceptions, and log activities. The video also demonstrates running and testing the application, focusing on proper shutdown procedures.

What is the primary purpose of creating a consumer demo with threads?

• To simplify code structure

• To reduce memory usage

• To increase data processing speed

• To improve application shutdown

In Java, what must be implemented when a class extends Runnable?

• The initialize method

• The execute method

• The run method

• The start method

What is the role of a latch in the consumer thread?

• To manage thread priority

• To initialize the consumer

• To handle concurrency

• To log errors

Which method is used to subscribe a Kafka consumer to a topic?

• joinTopic

• subscribe

• addTopic

• subscribeTo

What is the purpose of the wakeup method in the consumer thread?

• To reset the consumer

• To pause the consumer

• To interrupt the consumer poll

• To start the consumer

What should be done after catching a Wake Up exception?

• Terminate the application

• Ignore the exception

• Log the shutdown signal

• Restart the consumer

Why is it important to close the consumer after use?

• To free up memory

• To improve performance

• To prevent data loss

• To avoid resource leaks

What is the purpose of adding a shutdown hook in the application?

• To increase processing speed

• To manage thread execution

• To ensure graceful shutdown

• To log application errors

What programming style is used to create a function in a shutdown hook?

• Procedural programming

• Object-oriented programming

• Functional programming

• Lambda functions

What indicates that the application has exited successfully?

• The consumer is restarted

• A shutdown signal is received

• The application throws an exception

• The application logs an exit message
