In this video, I discuss some of the most important Java interview-based questions, focusing on practical coding solutions rather than just theoretical knowledge. We cover various topics, including filtering and counting transactions, transforming messy data into a consistent format, and finding distinct programming languages while sorting them. I also demonstrate how to find the first occurrence of an element after filtering and how to aggregate total revenue using Java 8's stream concepts.
