Calendar cal = Calendar.getInstance();
cal.setTime(d);
out.print(new java.text.SimpleDateFormat("yyyyMMdd").format(cal.getTime()));

package com.test;
import java.util.Calendar;
import java.util.Date;

public class Test1 {
public static void main(String[] args)throws Exception{
Calendar calendar=Calendar.getInstance();
Date date =calendar.getTime();
java.text.SimpleDateFormat dt = new java.text.SimpleDateFormat("yyyyMMdd");
String dateStr=dt.format(date);
System.out.println("current date:"+dateStr);

}
}

用Calendar的getTime()方法得到Date，再用SimpleDateFormat类来转化成你所需要的格式

import java.text.*;
import java.util.*;

public class Main {
public Main() {
}

public static void main(String[] args) {
Calendar cal = Calendar.getInstance();
Date dte = cal.getTime();
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
System.out.println(sdf.format(dte));
}
}

[xiaoyusong]

SimpleDateFormat simFmt = new SimpleDateFormat("yyyMMdd");
long now = System.currentTimeMillis();
Date dt = new Date(now);//或者其他日期
date_str = simFmt.format(dt);
return date_str;
