存储当前日期和日期1年从当前在java [英] store current date and date 1 year from current in java

问题描述

我已经有一切安装程序将当前日期存储到Java中的变量中。我想要弄清楚的是如何存储当前日期后1年的日期。

  import java.util。日期; 
 import java.text.SimpleDateFormat; 
 import java.text.DateFormat; 
 import java.util.Scanner; 
 import java.util.Calendar; 
  

这是我当前的日期：

  DateFormat newDate = new SimpleDateFormat（MM / dd / yyyy）; 
 Date date = new Date（）; 
 startDate = newDate.format（date）; 
  

所以如果今天是例如它将存储2/18/2013。我试图存储日期2/18/2014。如何不要这样做？

解决方案

如果不想拖动外部库，只需使用 calendar.add（Calendar.YEAR，1）

 日历cal = Calendar.getInstance（） ; 
日期今天= cal.getTime（）; 
 cal.add（Calendar.YEAR，1）; //获得上一年添加-1 
 Date nextYear = cal.getTime（）; 
  

注意，如果日期是 29 / Feb / 2012 你加了1年，你会得到 28 / Feb / 2013

I have everything setup already to store the current date to a variable in Java. What I am trying to figure out is how to store a date of 1 year after the current date.

import java.util.Date;
import java.text.SimpleDateFormat;
import java.text.DateFormat;
import java.util.Scanner;
import java.util.Calendar;

Here is what I have for the current date:

DateFormat newDate = new SimpleDateFormat("MM/dd/yyyy");
Date date = new Date();
startDate = newDate.format(date);

So if it were today for example it would store 2/18/2013. I am trying to store the date 2/18/2014. How would I go about doing this?

解决方案

If you do not want to drag external libraries, just use calendar.add(Calendar.YEAR, 1)

Calendar cal = Calendar.getInstance();
Date today = cal.getTime();
cal.add(Calendar.YEAR, 1); // to get previous year add -1
Date nextYear = cal.getTime();

Note, if the date was 29/Feb/2012 and you added 1 year, you will get 28/Feb/2013
