error in Date function

Hi
I am using date function as I have to display the date and day of one week starting from today in one comboBox and adding 6 months to this date in another combobox(as in MS project Information for Periodic Process)
For this I am using the following function which returns me a day and date, but the day returned is false.
Can anyone help me out or provide me any other simple answer

Calendar cal = Calendar.getInstance(TimeZone.getDefault());

for(int i = 0; i<7; i++)
    jComboBox11.addItem(getDate(new Date(cal.get(Calendar.YEAR),cal.get(Calendar.MONTH)+6, cal.get(Calendar.DAY_OF_MONTH)+i ), "E dd.MM.yy"));

public String getDate(Date dt, String format) {
    Date d = new Date(dt.getTime());
    if(format== null)
        format = "dd.MM.yyyy";
    java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat(format);

    return sdf.format(d);
  }

Thanks Balap

Can you add 6 months to this month (10) giving the 16th month, and call that a valid date?

I *think* you are trying to create a date that is the 28.16.2003 which is a bit wrong...

Try:

Calendar cal = Calendar.getInstance(TimeZone.getDefault());

cal.add( Calendar.MONTH, 6 ) ;
for( int i = 0 ; i < 7 ; i++ )
{
  jComboBox11.addItem( getDate( new Date( cal.getTimeInMillis() ), "E dd.MM.yy" ) ) ;
  cal.add( Calendar.DAY_OF_YEAR, 1 ) ;
}

Just because today is a tuesday, does not mean that in 6 months time it is a tuesday too...

Months are non-uniform (as are years)

WHat you *might* be meaning to do, is add 26 weeks instead of 6 months...

Calendar cal = Calendar.getInstance(TimeZone.getDefault());

cal.add( Calendar.WEEK_OF_YEAR, 26 ) ;
for( int i = 0 ; i < 7 ; i++ )
{
  jComboBox11.addItem( getDate( new Date( cal.getTimeInMillis() ), "E dd.MM.yy" ) ) ;
  cal.add( Calendar.DAY_OF_YEAR, 1 ) ;
}

Which gives you Tuesday the 27th April...

Not 6 months, but near enough, and the same day as today...
