Calendar get date and check difference two date : <p>I used the <code>Calendar.getInstance().get(Calendar.DATE)</code> to get current date. <br> So the output is today (2018/05/14).
I change the device time to <code>2018/06/17</code>. So I use the <code>Calendar</code> get the date. I got the <code>17</code>.<br>
My question is I want to get <code>05/15</code> <code>05/16</code> .... <code>06/01</code> ... <code>0616</code> these two days. I need to know all the difference days.<br>
So I don't know which function can do this.</p>
