java - Split zero in String -

guys have int value parse string [], should write:

---

if (first element == 0)  split return value without 0 @ start. 

for example have 01, 02, 03, 04, 05, 06, 07, 08, 09, 10,... 20... 30..

---

so in return in split 0 value 0 first element, , return me next:

---

1, 2, 3, 4, 5, 6, 7, 8, 9, 10,... 20... 30..

---

actually need calendar, i've take date return me days 01, 02, 03 , on. here method code:

---

public string setcurrentcalendarday() throws testexception, parseexception{         if (!getpage().getsession().canrun())             throw new testexception(page.invalidstatemessage);         string currentdate = "";         date date = new date();         calendar cal = calendar.getinstance();         cal.settime(date);         simpledateformat formatter = new simpledateformat("dd");         currentdate = formatter.format(date);         return currentdate;     } 

the first option use new simpledateformat("d") , not ("dd") have 1 digit minimum , not two.

the second option use regex 1 return currentdate.replacefirst("^0+(?!$)", "") replace first 0 nothing.
