title: What is the alternative method in Harmony OS for setFirstDayOfWeek() in DatePicker in Android OS?
body: <p>I am writing a custom component that allows users to choose a date from the calendar using JAVA SDK. I want to set a day as the first day of the week(e.g. MONDAY), which would then display the calendar with that day as the first day of the week(the first column of Calendar will be that day which was set).</p>
  <p>In Android, we have <code>setFirstDayOfWeek(int firstDayOfWeek)</code> method in DatePicker which does that for us.</p>
  <p>What is the alternative for the above in <code>DatePicker</code> of Harmony OS?</p>
  <p>Regards, Subham</p>
