Java 8 Stream API Interview Questions: Remove the Duplicate Value from List using Stream API in Java
Q35. Remove the Duplicate Value from List using Stream API #java8 #java8tutorials
Welcome to Learn Code With Saurabh! In this video, you will learn: Java program demonstrates how to use Java 8 Streams to perform conditional filtering on collections.
Explanation of the code:
This Java program demonstrates how to remove duplicates from a list of integers using Java 8 Streams API.
Key Steps:
1. Input List: A list of integers is created using Arrays.asList(), which includes duplicate numbers (e.g., [1, 2, 3, 4, 2, 5, 3, 6, 1]).
2. Stream Operations:
o numbers.stream() creates a stream from the input list.
o .distinct() is a method that filters out duplicate elements, retaining only unique numbers.
o .collect(Collectors.toList()) collects the resulting unique elements into a new list.
3. Output: The unique list (with duplicates removed) is printed to the console.
Example:
• Input: [1, 2, 3, 4, 2, 5, 3, 6, 1]
• Output: [1, 2, 3, 4, 5, 6]
