Java中把Date类型转换成Long类型

import java.util.Date;
import java.text.ParseException;
import java.text.SimpleDateFormat;

public class TimeToLong {

/**
* @param args
*/
public static void main(String[] args) throws ParseException{
// TODO Auto-generated method stub
Date d=new Date();
long t=d.getTime();
System.out.println(t);

//将字符串类型转化成Date类型
String s=”2009-08-04 14:37:47″;
SimpleDateFormat sdf=new SimpleDateFormat(“yyyy-MM-dd HH:mm:ss”);
Date d2=null;
d2=sdf.parse(s);//将String to Date类型
System.out.println(d2);

long t3=d2.getTime();
System.out.println(t3);
}

}
