Java Multithreading and Parallel Programming Masterclass - Thread Exception Handling

The video tutorial covers Java exceptions, focusing on checked and unchecked exceptions, and their handling in multithreaded environments. It explains the use of the 'throws' keyword, try-catch blocks, and the role of the Thread Group class in managing uncaught exceptions. The tutorial also discusses creating custom thread groups and using the default UncaughtExceptionHandler. Finally, it explores the order of exception handling, emphasizing the importance of understanding exception propagation in Java threads.

What are the two main types of exceptions in Java?

• Checked and Unchecked

• Compile-time and Runtime

• Static and Dynamic

• Synchronous and Asynchronous

How must checked exceptions be handled in Java?

• Using a finally block

• Using a try-catch block or 'throws' keyword

• By logging them

• By ignoring them

Which of the following is an example of an unchecked exception?

• IOException

• FileNotFoundException

• NullPointerException

• SQLException

What role does the Thread Group class play in exception handling?

• It compiles the code

• It prevents exceptions from occurring

• It handles uncaught exceptions

• It logs all exceptions

What is the purpose of the UncaughtExceptionHandler interface?

• To log exceptions

• To compile the code

• To handle exceptions not caught by the user

• To prevent exceptions

How can you create a custom thread group to handle exceptions?

• By implementing the Runnable interface

• By extending the Thread Group class

• By using a try-catch block

• By extending the Thread class

What method is used to set a default uncaught exception handler for a thread?

• Thread.setExceptionHandler

• Thread.setUncaughtExceptionHandler

• Thread.setDefaultExceptionHandler

• Thread.setHandler

In what order are uncaught exceptions handled?

• Thread level, Thread Group level, Default handler

• Default handler, Thread level, Thread Group level

• Default handler, Thread Group level, Thread level

• Thread Group level, Thread level, Default handler

What is the cleanest way to handle exceptions in a thread?

• Using a try-catch block around the code

• Ignoring the exceptions

• Using a finally block

• Logging the exceptions

Why is it important to experiment with exception handling in Java?

• To prevent any exceptions from occurring

• To make the code run faster

• To avoid writing any code

• To learn how the concepts work in practice
