Java 8 Stream API Interview Questions: Find Longest String in List Java 8 Stream API

Q17. Find the Length of the Longest String in a List using Java 8 Stream API | #java8 #streamapi
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:
The given LongestStringLength_17 Java program finds the length of the longest string in a list of words.
Key Steps:
1. Create a list of words: The list words contain "apple", "banana", "grapefruit", and "kiwi".

2. Use Stream to process the list:
o words.stream() converts the list into a stream.
o .mapToInt(String::length) maps each string to its length.
o .max() finds the maximum length among the strings.
o .orElse(0) ensures a default value of 0 if the list is empty.

3. Print the result: The longest string length is printed, which in this case will be 10 (for "grapefruit").
Output: Longest string length: 10
