Java 8 Stream API Interview Questions: Concatenate a List of Strings from List using Java 8 Stream

Q26 Convert List of Strings to a Single Concatenated String
Welcome to Learn Code With Saurabh! In this video, you will learn: the 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 convert a list of strings into a single concatenated string using the Java 8 Streams API.

2. Main Class: The class is named ConcatenateStrings_26.

3. Main Method:
o A list of strings named words is created, containing the values: "apple", "banana", and "orange".
o The program uses the Stream API to concatenate the strings:

4. Output: The program prints the resulting concatenated string: apple, banana, orange.

Key Features
• Stream API: The program leverages the power of the Stream API to efficiently process and manipulate collections in a functional style.
This program effectively illustrates how to use Java 8 Streams to concatenate a list of strings into a single string with a specified separator.

Great & helpful content, nice audio quality too..

StringBuilder sb = new StringBuilder();

1.

2. String joinedString =

3. String joinedString1 = String.join("", l3);
these three things worked for me
