Answer 5

自已处理，很简单

public class TimeStamp {
public String getTimeStamp() {
return getDate()+getTime();
}

//private Date param=null;
private Calendar ca=Calendar.getInstance();

private String getYear()
{
int y = ca.get(Calendar.YEAR);
String year = ""+y;
return year;
}
private String getMonth()
{
int m = 1+ca.get(Calendar.MONTH);
String month ="";
if(m<10)month="0"+m;
else month=""+m;
return month;
}
private String getDay()
{
int d = ca.get(Calendar.DAY_OF_MONTH);
String day ="";
if(d<10)day="0"+d;
else day=""+d;
return day;
}
private String getHour()
{
int h = ca.get(Calendar.HOUR_OF_DAY);
String hour = "";
if(h<10)hour="0"+h;
else hour =""+h;
return hour;
}

private String getMinute()
{
int n = ca.get(Calendar.MINUTE);
String minute = "";
if(n<10)minute="0"+n;
else minute=""+n;
return minute;
}

private String getSecond()
{
int s = ca.get(Calendar.SECOND);
String second = "";
if(s<10)second="0"+s;
else second=""+s;
return second;
}
public String getDate()
{
return getYear()+getMonth()+getDay();
}

public String getDate2()
{
return getYear()+"/"+getMonth()+"/"+getDay();
}
public String getDate3()
{
return getMonth()+"/"+getDay()+"/"+getYear();
}

public String getTime()
{
return getHour()+ getMinute()+ getSecond();
}

public String getTimes()
{
return getYear()+"-"+getMonth()+"-"+getDay()+" "+getHour()+":"+ getMinute()+":"+ getSecond();
}
}
