我正在制作一个程序,显示所选国家的时钟和zime区域。 单击按钮时,该时间显示为jLabel。 问题是,当我点击一次时间显示在标签中,但当我点击第二个时间被重写为现有的标签日期(文本)。Jlabel时钟java swing
如何显示未被重写的日期。 如果再次点击,时间将不可读。
这里是我的代码:
public class Window extends JFrame {
JLabel title, text,date1,label1;
JTextField country;
JButton search;
private static final String DATE_FORMAT = "dd-M-yyyy hh:mm:ss a";
public Window() {
super("Genesys");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(600,470);
setVisible(true);
setLayout(null);
//------Labels-------
title = new JLabel ("Genesys Time");
add (title);
text = new JLabel("Continent/Country:");
add(text);
//--------TextFileds------
country = new JTextField();
add (country);
//----------Buttons-------
search = new JButton("Cauta");
add (search);
title.setBounds(10,1,100,100);
text.setBounds(10,100,150,20);
country.setBounds(150,100,200,20);
search.setBounds(10,150,100,20);
search.addActionListener(new csearch());
}
class csearch implements ActionListener {
public void actionPerformed(ActionEvent event) {
//dispose();
//WindowTime wt = new WindowTime(null);
date1 = new JLabel();
date1.setVisible(false);
SimpleDateFormat formatter = new SimpleDateFormat(DATE_FORMAT);
Date date = new Date();
// String dateInString = "02-11-2016 12:06:55 AM";
// Date date = formatter.parse(dateInString);
TimeZone tz = TimeZone.getDefault();
// From TimeZone Asia/Singapore
System.out.println("TimeZone : " + tz.getID() + " - " + tz.getDisplayName());
System.out.println("TimeZone : " + tz);
System.out.println("Date (Ro - UTC+02:00) : " + formatter.format(date));
// To TimeZone America/New_York
SimpleDateFormat sdfAmerica = new SimpleDateFormat(DATE_FORMAT);
SimpleDateFormat sdfParis = new SimpleDateFormat(DATE_FORMAT);
DateTime dt = new DateTime(date);
DateTimeZone dtZone = DateTimeZone.forID(country.getText());
DateTime dtus = dt.withZone(dtZone);
TimeZone tzInAmerica = dtZone.toTimeZone();
Date dateInAmerica = dtus.toLocalDateTime().toDate(); //Convert to LocalDateTime first
sdfAmerica.setTimeZone(tzInAmerica);
date1.setText(String.valueOf(dateInAmerica));
add(date1);
date1.setBounds(10,200,1000,40);
}
}
}
谁能帮助我?
谢谢,它工作。我不知道我是如何犯这样一个错误的。 – Bogdan
