Java日期格式處理，java日期格式

處理日期格式，運行main函數即可：

package testutil;import java.text.SimpleDateFormat;import java.util.Calendar;import java.util.Date;/** * Created by wangpeng on 2018/2/26. */public class DateFormat {    public static void main(String[] args) {        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");        SimpleDateFormat sdf1 = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");        SimpleDateFormat sdf2 = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss");        Date date = new Date();        Calendar calendar = Calendar.getInstance();        calendar.setTime(date);        calendar.add(Calendar.DAY_OF_MONTH, -1);        date = calendar.getTime();        System.out.println(sdf.format(date));        System.out.println(sdf1.format(date));        System.out.println(sdf2.format(date));    }}
