I Have the following Java program in which converts Date to Words and the only thing I have to do now is add a boolean for a leap year. ( I am using Apache NetBeans) please explain where the boolean goes. Like this: I need the code working with the boolean added, Thank you!!! package a1_demo; import java.util.Scanner; public class MainApp { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.print("Welcome to the Date to Words Converter!\n\n"); while ( true ) { // get user input String str_MM_DD_YYYY = Validator.getString( Validator.sc, "Enter date in MM/DD/YYYY format: " ); // convert text to ints: // "11/22/3333" - > int, int int String[] dateComponents = str_MM_DD_YYYY.split( "/" ); if ( dateComponents.length != 3 ) { System.out.println("\t\t Bad input, please retry..."); continue; } int month = 0; int day = 0; int year = 0; try { month = Integer.parseInt(dateComponents[ 0 ]); day = Integer.parseInt(dateComponents[ 1 ]); year = Integer.parseInt(dateComponents[ 2 ]); } catch ( java.lang.NumberFormatException ex ) { System.out.println("\t\t numeric values are expected, please retry..."); continue; } Date2TextConverter converter = new Date2TextConverter( month, day, year ); System.out.print( converter.month2text() ); System.out.print( " " ); System.out.print( converter.day2text() ); System.out.print( " " ); System.out.print( converter.year2text() ); System.out.println(); }// endless while loop }//main }//class MainApp package a1_demo; public class Date2TextConverter { //--------------------------------------- // data //--------------------------------------- int month = 0; int day = 0; int year = 0; //--------------------------------------- // constructors //--------------------------------------- public Date2TextConverter(int month, int day, int year ) { this.month = month; this.day = day; this.year = year; }//Date2TextConverter //--------------------------------------- // operations //--------------------------------------- public String month2text() { switch( month ) { case 1: return "Jan"; case 2: return "Feb"; case 3: return "Mar"; case 4: return"April"; case 5: return"May"; case 6: return"June"; case 7: return"July"; case 8: return"Aug"; case 9: return"Sep"; case 10: return"Oct"; case 11: return"Nov"; case 12: return"Dec"; //... default: return "Invalid Month"; } }//month2text public String day2text() { //return Integer.toString( day ); return number2words (day); }//day2text public String year2text() { int century = year / 100; int yearInCentury = year % 100; String centuryText = number2words( century ); String yearText = number2words( yearInCentury ); if ( yearInCentury < 10 ) { return centuryText + " zero " + yearText; } else { return centuryText + " " + yearText; } }//year2text private String number2words( int number ) { // convert to text a number 0 through 99 if ( number < 20 ) { // 0, 1, 2, 3, ..., 19 return zero2nineteen[ number ]; } else if ( number % 10 == 0 ) { // 20, 30, 40, ... 90 return .
