Write a Java program which accept the value of n from user and print First N buzz Number.

A Buzz Number is a number that is either divisible by 7 or ends with 7. Here's a Java program that takes an integer n as input and prints the first n Buzz Numbers using a do while loop:

Solution

public class BuzzNumber {
    public static void main(String[] args) 
    {
        Scanner scanner = new Scanner(System.in);
        System.out.print("Enter the value of n: ");
        int n = scanner.nextInt();
        int count = 0; // To count the number of Buzz Numbers found
        int number = 1; // To check each number starting from 1
        System.out.println("The first " + n + " Buzz Numbers are:");
        // Use a do-while loop to find and print the first n Buzz Numbers
        do {
            if (number % 7 == 0 || number % 10 == 7) {
                System.out.print(number + " ");
                count++;
            }
            number++;
        } while (count < n);
    }
