What You’ll Learn:
Filtering Strings: How to filter out specific elements from a list using filter().
Transforming Data: Using map() to convert data and modify elements in the list.
Sorting Strings: Sorting a list of strings based on specific criteria.

Finding Elements: Using findFirst() and findAny() to search within a stream.
Reducing Data: Applying reduce() to aggregate or combine elements of a list.
Advanced Examples: Solving complex coding challenges and interview-style problems using Streams.
These techniques are not only helpful for interviews but will also enhance your day-to-day coding skills. Whether you’re a beginner or intermediate Java developer, this video will give you the tools to handle Stream-related questions with confidence.
