日历构造函数 Java toString

What I'm trying to do is pass a date into the Calendar so that it will format the date ready for use with another constructor. So that i can make use of it later using the functions that calendar has provides.

public class Top {
public static void main(String[] args) {
    Something st = new Something(getCalendar(20,10,2012));       
    System.out.println(st.toString());       
    }

public static Calendar getCalendar(int day, int month, int year){
    Calendar cal = Calendar.getInstance();
    cal.set(Calendar.YEAR, year);
    cal.set(Calendar.MONTH, month);
    cal.set(Calendar.DAY_OF_MONTH, day);
    return cal;
    }
}

tostring 方法.

public String toString(){
    String s = "nDate: " + DateD;
    return s;
}
