更改日期格式Java [英] Change Date format Java

问题描述

我尝试使用简单的日期格式化程序更改日期的格式，但我想将其保留为日期。现在，这是我在做什么：

I'm trying to change the format of a date using a simple date formatter, but I want to keep it as a date. At the moment, this is what I am doing:

public static Date getDate()
  {
    DateFormat df = new SimpleDateFormat("dd/MM/yyyy");
    Calendar c = Calendar.getInstance();
    df.format(c.getTime());
    return df.format(c.getTime());
  }

目前以字符串的形式返回日期，返回日期？我不确定这个。

This currently returns the date as a string, but how could I get it to return as a date? I'm unsure about this.

推荐答案

我只是猜测，但如果你想定义另一个字符串格式的java .util.Date，而不是总是必须通过日期格式化运行，那么你可以继承Date和覆盖toString方法。

I'm just guessing, but if you want to define another string format of a java.util.Date and not always have to run that through a dateformatter, then you can subclass Date and override the toString-method.

这样：

public class MyDate extends Date {

public MyDate() {
    super();
}

@Override
public String toString() {
    return new SimpleDateFormat("dd/MM/yyyy").format(this);
}

public static void main(String[] args) {
    MyDate d1 = new MyDate();
    System.out.println(d1);
}

}

我仍然不相信自己这是一个好主意，但它是可能的...

I have still not convinced myself that this is a good idea, but it's possible ...
