In this assignment, you will write a Java program that repeatedly asks the user for a date (of the form m/d/y), and then either prints that the date is invalid or prints the date in "long" format (monthName day, year). Here is a sample run of the program (user input is in red):

Enter date (m/d/y): 2/27/2018 2/27/2018 is February 27, 2018 Go again (y)? y Enter date (m/d/y): 4/31/2018 4/31/2018 is invalid. Go again (y)? Y Enter date (m/d/y): 2/29/2018 2/29/2018 is invalid. Go again (y)? y Enter date (m/d/y): 13/2/2018 13/2/2018 is invalid. Go again (y)? Y Enter date (m/d/y): 2/29/2016 2/26/2016 is February 29, 2016 Go again (y)? n 

Requirements

This program should contain a single class (called Proj5). This project has been started for you -- you will need to download Proj5.java from Canvas. Copy all the text in that file, and when you create a new class in BlueJ, paste the code in the BlueJ file. Do not change any of the completed code from that file.

This project contains several methods, each of which contains documentation on what that method does or is supposed to do. You will need to complete the following methods:

public static String monthNumToName(int m)

public static String getLongFormat(int m, int d, int y)

public static boolean checkValidity(int m, int d, int y)

public static void main(String[] args)

I suggest completing the methods in the order listed above.

Assumptions

You may make the following assumptions in your program:

The user will always enter the date in the form m/d/y, where m, d, y are all integers

The user will always enter either y, Y, n, or N when asked if they want to go again

public static void main(String[] args) {

Scanner s = new Scanner(System.in);

char more = 'y';

do {

//This code is done -- it gets the date and breaks it into month,day,year

System.out.print("Enter date (m/d/y): ");

String date = s.nextLine();

StringTokenizer st = new StringTokenizer(date, "/");

int month = Integer.parseInt(st.nextToken());

int day = Integer.parseInt(st.nextToken());

int year = Integer.parseInt(st.nextToken());

//Now if the user typed 2/27/2018, then month=2, day=27, and year=2018

//YOU DO THIS

//Call checkValidity to see if the date is valid

//If it isn't, print an error

//Otherwise

//Call getLongFormat to get the long format of this date

//Print the result from getLongFormat

//This code asks if the user wants to go again. It will loop while they enter y/Y.

System.out.print(" Go again (y)? ");

more = (s.nextLine()).charAt(0);

System.out.println();

} while (more == 'y' || more == 'Y');
