Welcome to Learn Code With Saurabh! In this video, you will learn: This Java program converts a list of lowercase strings to uppercase using Java 8 Streams. Here's a summary:
Input: A list of strings ("java", "spring", "lambda", "collections").
The stream() method is called on the list to process each string.
