In this lab, you add the input and output statements to a partially completed Java program. When completed, the user should be able to enter a year and then click the OK button, enter a month and then click the OK button, and enter a day and then click the OK button to determine if the date is valid. Valid years are those that are greater than $0,$ valid months include the values $1$ through $12,$ and valid days include the values $1$ through $31.$

Write the simulated housekeeping$()$ function that contains the prompts and input statements to retrieve a year, a month, and a day from the user. Include the output statements in the simulated endOfJob$()$ funcoThe format of the output is as follows:

month$/$day$/$year is a valid date.

or

month$/$day$/$year is an invalid date.

The rest of the program is written for you.

Execute the program entering the following:

month $=5,$ day $=32,$ year $=2014.$

and

month $=9,$ day $=21,$ year $=2002.$

An example of the program is shown below:

Enter year: $2002$

Enter month: $9$

Enter day: $21$

$9/21/2002$ is a valid date.

Code that needs to be changed:

import javax.swing.JOptionPane;

public class BadDate

$\{$

public static void main$($String args$[])$

$\{$

$//$ Declare variables

String yearString;

String monthString;

String dayString;

int year;

int month;

int day;

boolean validDate $=$ true;

final int MIN$\_$YEAR $=0,$ MIN$\_$MONTH $=1,$ MAX$\_$MONTH $=12,$ MIN$\_$DAY $=1,$ MAX$\_$DAY $=31$;

$//$ 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;

$//$ This is the work of the endOfJob$()$ method

$//$ Test to see if date is valid and output date and whether it is valid or not

if$($ validDate $==$ true $)$
