时间格式化问题？

[lord_is_layuping]

类似这种格式的字符串“08 1 2009 12:00AM”如何格式化为 1字符串类型"2009 08 01" 2Date类型"2009 08 01"

[dajiadebeibei9]

如果是字符串 用repalce()最方便
Data类型就用
Calendar cal = Calendar.getInstance(); 
java.text.SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd"); 
String cdate = sdf.format(cal.getTime()); 
System.out.println("times is :"+cdate);

/**
* 获取当前日期信息
*
* @param value
* @return
*/

public static String GetCurrentDateTime(int value) {
String dateTime = "";
int Year = 0;
int Month = 0;
int Day = 0;
int Hour = 0;
int Minute = 0;
int Second = 0;
Calendar cl = Calendar.getInstance(TimeZone.getDefault());
Year = cl.get(Calendar.YEAR);
Month = cl.get(Calendar.MONTH) + 1;
Day = cl.get(Calendar.DATE);
Hour = cl.get(Calendar.HOUR_OF_DAY);
Minute = cl.get(Calendar.MINUTE);
Second = cl.get(Calendar.SECOND);

dateTime = String.valueOf(Year) + "-" + String.valueOf(Month) + "-"
+ String.valueOf(Day);
return dateTime;
}

SimpleDateFormat sourceFormat = new SimpleDateFormat("MM dd yyyy hh:mmaa",
		new DateFormatSymbols(Locale.US));
SimpleDateFormat destFormat=new SimpleDateFormat("yyyy MM dd");
Date sourceDate = sourceFormat.parse("08 1 2009 12:00AM");
String strTime=destFormat.format(sourceDate);
System.out.println(strTime);

[Stonesk]

Date date=new Date();
SimpleDateFormat sdf=new SimpleDateFormat("yyyy MM dd ");
sdf.format(date);
out.println("当前时间为："+ sdf.format(date) );

用SimpleDateFormat类就好了

[Miracle1216]

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

public class DataFormatDemo {

  public static void main(String[] args) throws Exception {
    String str = "08 1 2009 3:00PM";
    SimpleDateFormat format = new SimpleDateFormat("MM d yyyy hh:mma");
    Date time = format.parse(str);
    format.applyPattern("yyyy MM dd");
    System.out.println(format.format(time));

  }
}

上面

format.format(time));就是字符串类型的。

Date好像没有类型吧，只有输出的时候指定格式啊。

Date time = format.parse(str);

得到的就是了。
