在Android中将字符串转换为日期格式

public class Utils {    public static void main(String[] args) {        String mytime="Jan 17, 2012";        SimpleDateFormat dateFormat = new SimpleDateFormat(     "MMM dd, yyyy");        Date myDate = null;        try { myDate = dateFormat.parse(mytime);        } catch (ParseException e) { e.printStackTrace();        }        SimpleDateFormat timeFormat = new SimpleDateFormat("yyyy-MM-dd");        String finalDate = timeFormat.format(myDate);        System.out.println(finalDate);    }}
