Core Java Programming Course- What is an Exception?

This video tutorial introduces exceptions in Java, explaining how they disrupt program flow and how Java handles them. It provides examples of common exceptions like NullPointerException and ArithmeticException, and discusses the creation of exception objects and their handling by the JVM. The tutorial also introduces key exception handling keywords such as try, catch, and throws, setting the stage for more detailed exploration in future sessions.
