Hi Guys, how are you all. I seem to be having a problem getting my program to highlight the date which is typed as the third command line argument. There are three command line arguments; 1st one is the starting date, second is the month, and the third is the date to highlight.

Here is the code:

 
// Program to print a calendar for a given month.
// First argument is the number of the start day, 1 to 7
// Second argument is the last date in the month e.g. 28.
public class CalendarHighlight
{
  public static void main(String [] args)
  {
    printMonth(Integer.parseI
nt(args[0]), Integer.parseInt(args[1]));
 
  } // main
 
  // Print the calendar for the month.
  private static void printMonth(int monthStartDay, 
                                 int lastDateInMonth)
  {
    // Keep track of which day 1 to 7 is the next day to be printed
    // out.
    int nextDayColumnToUse = monthStartDay;
 
    // Keep track of next date to be printed out.
    int nextDateToPrint = 1;
 
    // Print top line of calendar.
    printMonthLineOfHyphens();
 
    // Print headings i.e. su, mo, tu etc.
    printDayNames();
 
    // Print out minimum 6 rows to ensure consistent format.
    int noOfRows = 0;
    while (nextDateToPrint <= lastDateInMonth || noOfRows < 6)
    {
      // Print one row.
      System.out.print(" | ");
      for (int dayColumnNo = 1; dayColumnNo <= 7; dayColumnNo++)
      {
	// Print a space separator between day columns.
        if (dayColumnNo > 1)
	  System.out.print("    ");
 
	// We either print spaces or date.
	if (dayColumnNo != nextDayColumnToUse
	    || nextDateToPrint > lastDateInMonth)
	  printDateSpace();
	else
	{
	  printDate(nextDateToPrint);
	  nextDayColumnToUse++;
	  nextDateToPrint++;
	} // else
      } // for
 
      // Print separator and end the row.
      System.out.println(" | ");
      noOfRows++;
 
      // The next row.
      nextDayColumnToUse = 1;
    } // while
 
    // Print bottom line of calendar.
    printMonthLineOfHyphens();
  } // printMonth
 
  // Print line of hyphens as wide as table starting with
  // spaces and ending with spaces so it looks right.
  private static void printMonthLineOfHyphens()
  {
    System.out.print("  ");
    for (int dayColumnNo = 1; dayColumnNo <= 7; dayColumnNo++)
    {
      if (dayColumnNo > 1)
        System.out.print("---");
      printDateHyphens();
    } // for
    System.out.println("    ");
  } // printMonthLineOfHyphens
 
  // Print headings of days in the week.
  private static void printDayNames()
  {
    System.out.print(" | ");
    for (int dayColumnNo = 1; dayColumnNo <= 7; dayColumnNo++)
    {
      if (dayColumnNo > 1)
        System.out.print("    ");
      printDayName(dayColumnNo);
    } // for
    System.out.println(" | ");
  } // printDayNames
 
  // Print Day names as two characters.
  private static void printDayName(int dayNo)
  {
    // Days in the week are numbered 1 - 7 from sunday so:
    switch (dayNo)
    {
      case 1: System.out.print("Su"); break;
      case 2: System.out.print("Mo"); break;
      case 3: System.out.print("Tu"); break;
      case 4: System.out.print("We"); break;
      case 5: System.out.print("Th"); break;
      case 6: System.out.print("Fr"); break;
      case 7: System.out.print("Sa"); break;
    } // switch
  } // printDayName
 
  // Print spaces as wide as date between the dates.
  private static void printDateSpace()
  {
    System.out.print("  ");
  } // printDateSpace
 
  // Print hyphens as wide as the date.
  private static void printDateHyphens()
  {
    System.out.print("---");
  } // printDateHyphens
 
  // Print date using two characters, with leading zero if required.
  private static void printDate(int date)
  {
    System.out.printf("%02d", date);
  } // printDate
 
 
} // class CalendarHighlight

Any suggestions guys?

Kind regards
