Java Programming for Complete Beginners - Java 16 - Step 12 - Write less code with Try with Resources - New Feature in J

The video tutorial discusses the cumbersome nature of writing finally code in Java and introduces the try with resources feature introduced in Java 7. This feature simplifies exception handling by automatically closing resources, eliminating the need for explicit finally blocks. The tutorial explains how to implement try with resources, highlighting the role of the AutoClosable interface, which allows resources to be closed automatically. The video concludes by emphasizing the benefits of this feature in simplifying code and improving resource management.
