Java Programming for Complete Beginners - Java 16 - Step 08 - Hierarchy of Errors and Exceptions - Checked and Runtime

The video tutorial explains the concept of exception handling in Java, focusing on the exception hierarchy. It introduces the superclass Throwable and its subclasses Error and Exception. Errors are issues that cannot be handled by programmers, such as out-of-memory errors. Exceptions, however, can be managed and are divided into runtime exceptions and checked exceptions. Runtime exceptions do not require explicit handling, while checked exceptions must be handled or declared to be thrown. The tutorial emphasizes understanding the exception hierarchy to effectively manage exceptions in Java programming.
