Question

File name: dateexception.cpp
Write a program that converts dates from numerical month/day format to alphabetic
month/day(for example1/31 or 01/31 corresponds to January 31). Throw a string
exception if the user enters anything other than a legal month number (integers
from 1 to 12. Similarly, throw a string exception if the user enters an invalid
day number(integers from 1 to either 29, 30, or 31, depending on the month). To
keep things simple, always allow 29 days for February.
Test your code by catching your exception

Explanation / Answer

import java.util.StringTokenizer;

import java.util.Scanner;

public class DateParser {

public static void main(String[] args) {

Scanner sc=new Scanner(System.in);

System.out.print("Enter a date in the format MM/DD/YYYY:");

String input =sc.nextLine();

String month = "";

String day = "";

String year = "";

StringTokenizer tok = new StringTokenizer(input,"/");

int count =tok.countTokens();

if(count>0)

{

month=tok.nextTokens();

if(count>1)

{

day=tok.nextToken();

if(count>2)

{

year=tok.nextToken();

}

}

}

boolean done=false;

while(!done)

{

try{

String formatted = formatDate(month, day, year);

System.out.println("You entered: "+formatted);

done = true;

}

catch(MonthException me){

System.out.println("The month you entered(""+me.getMonth()+"") is not valid. Please re-enter the month [1-12]:");

month = sc.nextLine();

}

catch(DayException de) {

System.out.println("The day you entered (""+de.getDay()+"" is not valid. Please re-enter the day [1- " + de.getMaxDayForMonth()+"]:");

day = sc.nextLine();

}

catch(YearException ye){

System.out.print("The year you entered (""+ ye.getYear+"" is not valid. Please re-enter the year [1000-3000]:");

year = sc.nextLine();

}

}

}

public static String formatDate(String month, String day, String year)
throws MonthException, DayException, YearException {
}
