Java Programming for Complete Beginners - Java 16 - Step 03 - Basics of Handling Exceptions - try and catch

The video tutorial explains the concept of stack trace and how exceptions flow up the call chain. It introduces the try-catch block in Java for handling exceptions, demonstrating how to prevent exceptions from propagating to calling methods. The tutorial emphasizes the importance of exposing exceptions and printing stack traces for debugging. It concludes with a summary of key points about exception handling and visibility in methods.

What is the purpose of a stack trace in exception handling?

• To prevent exceptions from occurring

• To handle exceptions automatically

• To provide a list of method calls leading to an exception

• To execute code after an exception

What is the first step in setting up a class for exception handling?

• Writing a try-catch block

• Copying and pasting the class

• Logging the exception

• Throwing an exception

Which of the following is true about the try-catch block syntax?

• It automatically resolves exceptions

• It is simple and involves starting a block with 'try'

• It is used to execute code after an exception

• It is complex and difficult to understand

What happens if an exception is caught in a method and not propagated?

• The program crashes

• The exception is hidden from the calling methods

• The exception is logged and the program stops

• The exception is visible to the calling methods

Why is it important to print the stack trace when handling exceptions?

• To ensure the program fails

• To inform the user of the exception

• To log the exception for debugging purposes

• To automatically fix the exception

What is the effect of handling an exception within a method?

• The exception is hidden from the calling method

• The exception is logged and the program stops

• The exception is propagated to the calling method

• The program crashes

What is the consequence of not handling exceptions properly?

• The program may fail silently

• The exception will be visible to all methods

• The program will run smoothly

• The exception will be automatically resolved
