Requirements:

No third-party libraries are allowed.

You may add Java code in the main method but do not modify the existed statements in HW4.java file.

You may use BufferedReader, Scanner …… to read the input file. To parse a string, you may refer to the Java StringTokenizer class or String class.

Classes required for the project:

1. You may use a java built-in structure: ArrayList, LinkedList, Stack, HashMap or TreeMap or the data structures or algorithms we implemented in class to store or sort data. Attach all classes you implement and/or use.
2. The main method must be in the HW4 class.

 

Your Java program must be submitted on Blackboard as attachments. NO .class files.

Any submissions that do not compile or work; or classes do not name as required above will receive a 0. Excuses such as “It compiled on my computer” or “It worked last time” will not be accepted. Your program must work on all machines not just yours.

import java.util.Scanner;

public class Hw4 {

	public static void main(String[] args) {
		
		boolean done = false;
		while (!done) {
			System.out.print("Year of Birth(2011-2017, yyyy): ");
			Scanner in = new Scanner(System.in);
			int year = in.nextInt();

			System.out.print("Gender(boy/girl): ");
			in = new Scanner(System.in);
			String gender = in.nextLine();

			System.out.print("Ethnicity(asian/black/hispanic/white): ");
			in = new Scanner(System.in);
			String ethnicity = in.nextLine();

			// closing scanner
			in.close();

			System.out.println("Popular baby " + gender +" names in " + ethnicity + " in " + year +":");
			//add code to print out the popular baby names by year of birth, gender and ethnic group
			
			System.out.print("Interested in more(yes/no): ");
			in = new Scanner(System.in);
			String more = in.nextLine();
			if (more.equalsIgnoreCase("no")) done = true;
		}
	}
