timestring.java

时间格式化,java.text.SimpleDateFormat类 能格式化日期成字符串,也能把字符串格式化成日期,废话少说,具体请看例子

package scz;

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

import org.yeeku.exception.ExamException;

public class TimeString implements ITimeString{
	SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
	SimpleDateFormat sdf1=new SimpleDateFormat("yyyy年MM月dd日 hh:mm:ss");
	SimpleDateFormat sdf2=new SimpleDateFormat("yyyy-MM-dd");
	SimpleDateFormat sdf3=new SimpleDateFormat("yyyy年MM月dd日");


	public Date getNowDate()throws ExamException  {
		// TODO Auto-generated method stub
			
		return new Date();
	}

	public String dateToString(Date date)throws ExamException  {
		// TODO Auto-generated method stub
		try {
			return sdf1.format(date);
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			throw new ExamException("日期转成字符串出错");
		}
		
	}

	public Date stringToDate(String str)throws ExamException {
		// TODO Auto-generated method stub
		try {
			return sdf.parse(str);
		} catch (ParseException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			throw new ExamException("字符串转成日期出错");
		}
	}
	public String dateToStringTo(Date date)throws ExamException  {
		// TODO Auto-generated method stub
		try {
			return sdf1.format(date);
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			throw new ExamException("日期转成字符串出错");
		}
		
	}

	public Date stringToDateTo(String str)throws ExamException {
		// TODO Auto-generated method stub
		try {
			return sdf.parse(str);
		} catch (ParseException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			throw new ExamException("字符串转成日期出错");
		}
	}
	public static void main(String[] args) {
		// TODO Auto-generated method stub

	}
