在调用方法和 JOptionPane 后允许代码继续执行所需的计时器或其他想法 [英] Timer or other idea required to allow code to continue execution after calling method and JOptionPane

问题描述

我需要一种方法来让我的程序在调用此方法后继续运行代码.

目前，它等待半小时，获取信息，将其存储到对象 WeatherCard，并显示它，然后重复.但它挂在 JOptionPane 上.我需要一种方法来使程序要么继续在 JOptionPane 下运行，要么在大约 10 秒后关闭该窗格.我不确定如何在我的代码中工作，目前

I need a way to allow my program to keep running code after this method is called.

Currently, it waits for half an hour, gets the info, stores it to the object WeatherCard, and displays it, and repeats. But it hangs on the JOptionPane. I need a way to make it so that the program either keeps going underneath the JOptionPane or to close the pane after about 10 seconds. I am not sure how to work either into my code, currently

public void printWeatherCard(WeatherCard w, JFrame controlFrame) throws MalformedURLException, IOException{
    /* Displays a dialog box containing the temperature and location */
    BufferedImage img = ImageIO.read(new URL(w.imgSrc));
    ImageIcon icon = new ImageIcon(img);

    JOptionPane.showMessageDialog(controlFrame, "It is currently " + w.currentTemp + " u00B0 F in " + w.location.city + ", " + w.location.state + ".
Current humidity: " + w.currentHumidity + 
            "%.
Chance of precipitation: " + w.chancePrecip + "%.", "Weather Update: " + w.location.zipCode, JOptionPane.INFORMATION_MESSAGE, icon);
}

有两种方式

• (更容易、更舒服)创建JDialog(JFrame parent, boolean true)，默认关闭操作HIDE_ON_CLOSE，只有一个JDialog 作为local variable，通过setVisible(false/true)

• (better easier, comfortable) create JDialog(JFrame parent, boolean true), with default close operation HIDE_ON_CLOSE, only one JDialog as local variable, reuse this Object by setVisible(false/true)

在所有 JOptionPanes 的数组内循环(所有这些都存在直到当前 JVM 处于活动状态) by @kleopatra
