Question

Code with Java using arrays and Scanner only ( input should end with 0 to terminate the program)

Everyone loves to be celebrated on their birthdays. Birthday celebration can encourage positive social interaction among co-workers, foster friendship among classmates or even strengthen bond between families.

Birthday graph can be display in many forms. It can a creative drawing consists of cupcakes, balloons, candles with names, or it can be in the form of simple bar chart to indicate the birthday frequency for the month.

Birthday graph apps will come handy to tabulate birthdates by month especially for a large group. Your task is to write a program that reads a list of birthdates and display the birthday graph as shown in the sample output below.

Input

The input consists of a few test cases. For each test case, the first line of input is a positive integer N (N ≤ 100) which indicates the number of data in the test case. Each of the following N lines contains a valid date representing birthdays formatted as dd mm yyyy. Input is terminated by a test case where N is 0.

Output

For each test case, output a line in the format "Case #x:" where x is the case number (starting from 1), follow by the monthly birthday graph as shown in the sample output.

Answer 1

Thanks for the question, here is the complete code in JAva. Few things you need to do when running it.

Please keep a file by the name birthdays.txt (screenshot below) and then update the below line inside the main method. I kept the file name in my F drive so same way you too need to keep the file and then update the file path in the below line. Thats it.

String fileName = "F:\\birthdays.txt"; 

Here is the code in Java and the screenshot of the output. If you are satisfied with the solution, please rate the answer.

Thank You !

import java.util.Scanner;

public class BirthdayGraph {

    public static void main(String[] args) {


        Scanner scanner = new Scanner(System.in);
        int testCase = 0;
        int count = 0;
        do {

            count = scanner.nextInt();
            int months[] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
            int day = 0, month = 0, year = 0;
            for (int i = 1; i <= count; i++) {
                day = scanner.nextInt();
                month = scanner.nextInt();
                year = scanner.nextInt();
                months[month - 1] += 1;
            }
            testCase += 1;
            if (count > 0) displayGraph(testCase, months);

        } while (count != 0);


    }

    private static void displayGraph(int testCase, int[] months) {
        System.out.println("Case #" + testCase + ":");
        String monthNames[] = {"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"};
        for (int i = 0; i < months.length; i++) {

            System.out.print(monthNames[i] + ": ");
            for (int stars = 1; stars <= months[i]; stars++) {
                System.out.print("* ");
            }
            System.out.println();
        }
    }
}
