Java Programming for Complete Beginners - Java 16 - Step 10 - Throwing a Checked Exception - Throws in Method Signature

The video tutorial explains the difference between runtime and checked exceptions in Java. It discusses how to handle checked exceptions using 'throws' and 'try-catch' blocks. The tutorial also covers creating custom exceptions to provide more specific error messages, such as a 'CurrenciesDoNotMatchException'. The importance of clear exception messages for debugging and application maintenance is emphasized.
