Two ways to get the current date and get all the dates of the current month

js obtain the current time yyyy-MM-dd hh: mm: ss

Date.prototype.Format = function (fmt) { // author: meizz
        var o = {
        "M+": this.getMonth() + 1, // 月份
        "d+": this.getDate(), // 日
        "h+": this.getHours(), // 小时
        "m+": this.getMinutes(), // 分
        "s+": this.getSeconds(), // 秒
        "q+": Math.floor((this.getMonth() + 3) / 3), // 季度
        "S": this.getMilliseconds() // 毫秒
    };
    if (/(y+)/.test(fmt))
        fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
    for (var k in o)
        if (new RegExp("(" + k + ")").test(fmt)) fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
            return fmt;
}
        var Time = new Date().Format("yyyy-MM-dd hh:mm:ss");

A: need to reference java.util.date

Date now = new Date();

SimpleDateFormat dateFormat = new SimpleDateFormat ( "yyyy / MM / dd HH: mm: ss"); // can easily modify the date format
String hehe = dateFormat.format (now); 

System.out.println(hehe); 

Two: you need to reference

Calendar java.util.Calendar.getInstance()

code show as below

Calendar c = Calendar.getInstance (); // can be individually modified for each time-domain
int year = c.get (Calendar.YEAR); 
int = month The c.get (the Calendar.MONTH) + 1'd; // get the month less than the current one, it is necessary + 1'd
int = DATE c.get (Calendar.DATE); 
// int hour = c.get (Calendar.HOUR_OF_DAY); 
// int = c.get minute (Calendar.MINUTE); 
/ / int second = c.get (Calendar.SECOND)  ;

String nowtime=year + "-" + month + "-" + date; 

Three: the current month all dates

                    List list = new ArrayList();
   Calendar aCalendar = Calendar.getInstance(Locale.CHINA);
   int year = aCalendar.get(Calendar.YEAR);//年份
   int month = aCalendar.get(Calendar.MONTH) + 1;//月份
   int day = aCalendar.getActualMaximum(Calendar.DATE);
   for (int i = 1; i <= day; i++) {
       String aDate = String.valueOf(year)+"-"+month+"-"+i;
       list.add(aDate);
   }
