DateField df = null;
Date date = df.getDate();
Calendar c = Calendar.getInstance();
c.setTime(date);
System.out.println(c.get(Calendar.YEAR)+"年"+ (c.get(Calendar.MONTH)+1) +"月");
//Calendar.YEAR的意思自己看文档,还有其他的field
date = c.getTime();
long longTime = date.getTime();

请问如果要用Calendar的getTimeInMillis方法将时间变为long，为何不行？
（提示protected无法access）

faint，中间少了一句：

cal.setTime(date);

不好意思。^_^

抛砖。

Calendar cal;
Date date;
cal = Calendar.getInstance();
date = new Date();

g.drawString(new StringBuffer().append(cal.get(Calendar.YEAR)).append("年").append(cal.get(Calendar.MONTH) +1).append("月").append(cal.get(Calendar.DATE)).append("日").toString(), 10, 10, 0);
g.drawString(new StringBuffer().append(cal.get(Calendar.HOUR_OF_DAY)).append(":").append(cal.get(Calendar.MINUTE)).append(":").append(cal.get(Calendar.SECOND)).toString(), 10, 30, 0);
