从 JSpinner (SWING) 获取价值 [英] Getting the value from JSpinner (SWING)

问题描述

我需要从 JSpinner 获取价值.

I need to get value from JSpinner.

private JSpinner[] timeSpinner;
private SimpleDateFormat format = new SimpleDateFormat("HH:mm:ss");

Date time = new Date();
try {
  time = format.parse(timeSpinner[i].getValue().toString());
} catch (ParseException e) {
  e.printStackTrace();
}
data[i] = time.toString();
System.out.println(data[i]);

错误信息:

java.text.ParseException: Unparseable date: "Thu Jan 01 01:05:00 CET 1970"

推荐答案

您正在创建的 SimpleDateFormat 与您尝试解析的日期格式不同:

The SimpleDateFormat you are creating has a different format from the date you are trying to parse:

new SimpleDateFormat("HH:mm:ss");

Thu Jan 01 01:05:00 CET 1970

查看 SimpleDateFormat 文档

实际上再看一遍，您似乎已经有了一个 Date 对象，为什么不直接使用它呢?

Actually looking again it looks like you already have a Date object why not just use that?

time = (Date)timeSpinner[i].getValue();

<小时>

为了将您拥有的日期转换为字符串，您只需执行上述操作即可获取日期，然后执行

---

In order to turn the date you have into a String you just have to do the above to get a Date and then do

String formattedDate = format.format(time);
