string datestr = sdf.format(calendar.gettime());

2.string 转化calendar

string str="2012-5-27";

simpledateformat sdf= new simpledateformat("yyyy-mm-dd");

date date =sdf.parse(str);

calendar calendar = calendar.getinstance();

4.string 转化date

string str="2012-5-27";

simpledateformat sdf= new simpledateformat("yyyy-mm-dd");

date date= sdf.parse(str);

5.date 转化calendar

calendar calendar = calendar.getinstance();

calendar.settime(new java.util.date());

6.calendar转化date

calendar calendar = calendar.getinstance();

java.util.date date =calendar.gettime();

7.string 转成 timestamp

timestamp ts = timestamp.valueof("2012-1-14 08:11:00");

8.date 转 timestamp

simpledateformat df = new simpledateformat("yyyy-mm-dd hh:mm:ss");

string time = df.format(new date());

timestamp ts = timestamp.valueof(time);
