What is the purpose of exception handling in software development, and how does it work?

Explain how exception handling support in programming languages can help software systems be more reliable.

Is there a way to summarize the compiler and elaborate on the significance of testability?

Consider the role that debugging may play in the development of more trustworthy programs.

What may happen if you lingered over a particularly chaotic chunk of code?

Why does testing just find errors?

How does the lock-and-keys approch potentially have a techinal impact on a language (e.g., how does it impact the programs written in that language, such as Java, C#, LISP)

What are the potential vulnerabilities related to Java exception handling?

If a programming language does not provide exception-handling facilities, it is common to have subprograms indicate an error either through return value or through an error out parameter. What are some disadvantages of this approach comapared to exception-handling facilities provided by programming languages such as C++ and Java?
