java 时间与字符串之间的转换

1. long字符串转换成yyyy-MM-dd HH:mm:ss格式输出

import java.text.SimpleDateFormat;
import java.util.Date;
//将long字符串转换成格式时间输出
public class LongToString {
public static void main(String argsp[]){
	String time="1256006105375";

	Date date=new Date(Long.parseLong(time));
	SimpleDateFormat formatter=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
	time=formatter.format(date);
	System.out.println(time);
}
}

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

import ognl.ParseException;

public class StringToDate {
public static void main(String argsp[]) throws Exception{
	String time="2010-11-20 11:10:10";

	Date date=null;
	SimpleDateFormat formatter=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
	date=formatter.parse(time);
	System.out.println(date);
}
}

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

public class StringToDate {
public static void main(String argsp[]) throws Exception{
	
	Date date=new Date();
	SimpleDateFormat formatter=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
	String time=formatter.format(date);
	System.out.println(time);
}
}

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

public class StringToDate {
public static void main(String argsp[]) throws Exception{
	
	Date date=new Date();
	SimpleDateFormat formatter=new SimpleDateFormat("HH:mm:ss");
	String time=formatter.format(date);
	System.out.println(time);
}
}

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

public class StringToDate {
public static void main(String argsp[]) throws Exception{
	
	String time="20101125102503";
	SimpleDateFormat formatter1=new SimpleDateFormat("yyyy-HH-dd HH:mm:ss");
	SimpleDateFormat formatter2=new SimpleDateFormat("yyyyHHddHHmmss");
	time=formatter1.format(formatter2.parse(time));
	System.out.println(time);
}
}
