将String类型的ArrayList转换为Date类型? [英] Convert ArrayList of String type into Date type?

问题描述

我有一个arraylist，它为我们提供了字符串类型的date.我想将字符串数组转换为日期数组；我该如何进行转换?

I have an arraylist which is providing us to string type date. I want to convert that string array into a date array; how can I do the conversion?

  ArrayList<String> dates = new ArrayList<String>();

我从中获得一些价值，例如:

where I am getting value some thing like:

2015-11-09
2015-11-08
2015-11-07
2015-11-06
2015-11-10

我想将其转换为Dates的ArrayList并以相同的格式返回相同的值.

I want to convert this into an ArrayList of Dates and return same value in same format.

推荐答案

您是否阅读过SimpleDateFormat?

Have you read up on SimpleDateFormat?

    ArrayList<String> dateStringList = new ArrayList<String>();
    ArrayList<Date> dateList = new ArrayList<Date>();

    dateStringList.add("2015-11-09");
    dateStringList.add("2015-11-08");

    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yy-MM-dd");

    for (String dateString : dateStringList) {
        try {
            dateList.add(simpleDateFormat.parse(dateString));
        } catch (ParseException e) {
            e.printStackTrace();
        }
    }

    for (Date date : dateList) {
        System.out.println("Date " + simpleDateFormat.format(date));
    }
