/* Program Name: BadDate.java Function: This program determines if a date entered by the user is valid. Input: Interactive Output: Valid date is printed or user is alerted that an invalid date was entered. */

// This is the work of the housekeeping() method // Get the year, then the month, then the day

// Convert Strings to integers

// This is the work of the detailLoop() method // Check to be sure date is valid if( year <= MIN_YEAR ) // invalid year validDate = false; else if ( month < MIN_MONTH || month > MAX_MONTH ) // invalid month validDate = false; else if ( day < MIN_DAY || day > MAX_DAY ) // invalid day validDate = false;

} else { // Output statement } } // end of main() method

1. write the stimulated housekeeping() method that contains input statements to retrieve a year, a month, and a day from the user.

2. Add statements to the stimulated housekeeping() method that convert the string representation of the year, month, day to ints.

3. include the output statements in the stimulated endOfJob() method. The format of the output is :

month/day/yeat is a valid date.

or

month/day/year is an invalid date.

4. compile code BadDate.java

5. execute by entering the following date: month=5, day=32, year=2014.

6. execute by entering the following date: month=9, day=21, year=2002.
