Complete Java SE 8 Developer Bootcamp - Throwable

The video tutorial explains how disruptions can affect the normal flow of a Java program, focusing on throwable objects. It describes how Java's infrastructure allows for the creation of throwable objects when something goes wrong, and how these objects are handled by the runtime system. The tutorial provides an example of a string index out of bounds exception and explains the information contained within a throwable object. It differentiates between exceptions and errors, emphasizing that exceptions can be handled and recovered from, while errors are typically catastrophic. The video also covers how to handle pre-built exceptions and create custom exceptions.

What is the primary role of a throwable object in Java?

• To encapsulate what went wrong during program execution

• To enhance the speed of the program

• To store user data securely

• To manage memory allocation

In the given example, what type of exception is created when accessing an invalid string index?

• NullPointerException

• ArrayIndexOutOfBoundsException

• StringIndexOutOfBoundsException

• IllegalArgumentException

What information does a throwable object provide about an error?

• The current memory usage

• The total runtime of the program

• A snapshot of the execution stack and a message

• The number of active threads

How are errors different from exceptions in Java?

• Errors are related to syntax, exceptions are not

• Errors are recoverable, exceptions are not

• Errors are catastrophic and usually unrecoverable, exceptions can be managed

• Errors occur only during compilation, exceptions occur during runtime

What can developers do if the pre-built exceptions in Java do not meet their needs?

• Create custom exceptions

• Request new exceptions from Oracle

• Ignore the exceptions

• Use a different programming language
