Top Coding Interview Questions in Streams API | Using a list of Strings - Part I

Welcome to our latest video on Top Coding Interview Questions in Java Streams API! In this session, we’ll tackle some of the most common and challenging interview questions that involve Java Streams, using a List of Strings as the data source. If you’re preparing for a Java developer interview or want to level up your coding skills, this video is packed with practical examples, tips, and solutions that will help you excel in your next interview. We’ll cover key concepts like filtering, mapping, sorting, and reducing using Java Streams, along with efficient ways to manipulate and process data. ----------------------------------------------------------------------------------------------------------------------- Given below are the questions that are discussed in this video Top 20 coding interview questions in Streams API Using List of Strings Basics 1. Convert a list of strings to uppercase , sort them and print 2. Get the list of strings where the length of each element is greater than 5 and get the count 3. Remove duplicates from a list 4. Get the list of strings having a particular word 5. Write a Java program to remove strings that start with a specific word from a list using streams. 6. Find the first element in a list that starts with a particular letter 7. Get the length of each name in a list Intermediate 8. Sort the list of strings based on their lengths in ascending/descending order. 9. Find the longest word in the list. 10. Get the list of strings having vowels 11. convert a list of strings into a single string, separated by commas, using streams 12. Write a Java program to create a new list of strings, where each string is reversed from the original list, using Java streams. 13. Write a Java program to remove all strings from the list that are empty or null using streams. Advanced 14. Given a list of strings, group a list of strings by the first letter of each string using streams 15. Given a list of strings, group a list of strings by the length of the string 16. Given a list of strings, create a map where the key is the first letter of the string, and the value is a list of strings that start with that letter using streams 17. Given a list of strings, group the list of strings with vowels and no vowels into two lists 18. Given a list of strings print only the string elements excluding the digits using streams. 19. Given a list of strings find the first element having the length as 10 if not handle exceptions 20. Reverse the list of strings using streams api 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.
