Java scenario based interview questions

You have a list of strings: ["apple", "banana", "cherry", "date", "fig", "grape"].
Write a code snippet to filter out strings starting with the letter 'b' and collect the remaining strings into a comma-separated single string.

import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;

public class StreamExample {
    public static void main(String[] args) {
        List<String> fruits = Arrays.asList("apple", "banana", "cherry", "date", "fig", "grape");

        // Filter strings not starting with 'b' and join them into a single string
        String result = fruits.stream()
                .filter(fruit -> !fruit.startsWith("b")) // Exclude strings starting with 'b'
                .collect(Collectors.joining(", "));     // Join remaining strings with ", "

        System.out.println(result); // Output: apple, cherry, date, fig, grape
    }
}

Explanation
filter(fruit -> !fruit.startsWith("b")): Filters out strings that start with the letter 'b'.

Collectors.joining(", "): Combines the remaining strings into a single string, separated by ", ".

System.out.println(result): Prints the final result.

Output
For the input ["apple", "banana", "cherry", "date", "fig", "grape"], the output will be:

apple, cherry, date, fig, grape
