Complete Java SE 8 Developer Bootcamp - Catching Exceptions

The video tutorial explains exception handling in Java, focusing on string index out of bounds exceptions. It covers how exceptions are thrown and the importance of stack traces in debugging. The tutorial demonstrates using try-catch blocks to handle exceptions, including multiple catch blocks for different exception types. It also discusses polymorphism in exception handling, allowing for catching exceptions and their subtypes. The video concludes with general exception handling strategies, emphasizing the importance of ordering catch blocks correctly to avoid compilation errors.

What is a String Index Out of Bounds Exception?

• An error when a string is too long

• An error when accessing a character beyond the string's length

• An error when a string is null

• An error when a string contains invalid characters

What is the purpose of a try block in Java?

• To define a block of code that might throw an exception

• To execute code that will always run

• To log errors to the console

• To catch and handle exceptions

What happens when an exception is thrown in a try block?

• The program jumps to the corresponding catch block

• The program terminates immediately

• The program continues executing the try block

• The program logs the error and continues

How can you handle multiple exceptions in Java?

• By using a finally block

• By using multiple catch blocks for different exceptions

• By using a single catch block for all exceptions

• By using multiple try blocks

What is the role of polymorphism in exception handling?

• It allows exceptions to be ignored

• It allows catching exceptions of different types in a single catch block

• It ensures only one type of exception can be caught

• It prevents exceptions from being thrown

What is a generic catch block used for?

• To log exceptions without handling them

• To handle only runtime exceptions

• To prevent exceptions from being thrown

• To handle all exceptions that are not specifically caught

What issue can arise from listing a general exception before a specific one?

• The specific exception will never be caught

• The program will run slower

• The program will not compile

• The general exception will be ignored
