java判断今天,昨天,前天,不能用秒间隔的简单实例
实例如下：
一jsonoptString解析的TimesTampstring
二longdateSec=(long)(Double.valueOf(timestamp)*1000);
三Datedate=newDate(dateSec);
四getTimestampString(date);
publicstaticStringgetTimestampString(DateparamDate){
Stringstr=null;
longl=paramDate.getTime();
CalendarlocalCalendar=GregorianCalendar.getInstance();
localCalendar.setTime(paramDate);
intyear=localCalendar.get(Calendar.YEAR);
if(!isSameYear(year)){//去年，直接返回
StringparamDate2str=newSimpleDateFormat("yyyyMMdd",Locale.CHINA).format(paramDate);
returnparamDate2str;
}
if(isSameDay(l)){
inti=localCalendar.get(Calendar.HOUR_OF_DAY);
if(i>17){
str="晚上HH:mm";//HH表示24小时,hh表示12小时进制，
}elseif((i>=0)&&(i<=6)){
str="凌晨HH:mm";
}elseif((i>11)&&(i<=17)){
str="下午HH:mm";
}else{
str="上午HH:mm";
}
}elseif(isYesterday(l)){
str="昨天HH:mm";
}elseif(isBeforeYesterday(l)){
str="前天HH:mm";
}else{
str="M月d日HH:mm";
}
StringparamDate2str=newSimpleDateFormat(str,Locale.CHINA).format(paramDate);
returnparamDate2str;
}
。。。
