JAVA_日期日历类的用法

public class TestDate {
	public static void main(String[] args) {
		Calendar c = new GregorianCalendar(2008, 7, 8, 20, 8, 8);// 构建一个特定时间
		Date d = c.getTime();// Date date = calendar.getTime();转换
		System.out.println(d);

		Date d2 = new Date();
		Calendar c2 = Calendar.getInstance();// new GregorianCalendar对象
		c2.setTime(d2);// Date转换为Calendar
		System.out.println(d2);
		System.out.println(d2.getTime()); // 获得从1970的毫秒值
		
		//格式显示时间
		SimpleDateFormat bartDateFormat = new SimpleDateFormat(
				"EEEE-MMMM-dd-yyyy");
		Date d3 = new Date();
		System.out.println(bartDateFormat.format(d3));
		
		//Strin转换为Date
		SimpleDateFormat bartDateFormat2 =
			new SimpleDateFormat("MM-dd-yyyy");
		String dateStringToParse = "8-29-2009";
		Date d4=null;
		try {
			d4 = bartDateFormat2.parse(dateStringToParse);
		} catch (ParseException e) {
			e.printStackTrace();
		}
		System.out.println(d4);
	}
