A simple Java digital clock developed using Netbeans IDE. The clock is been developed using Java.Util.GregorianCalender Class, which is subclass of Calender which provides the standard calender system. Java Thread is used to refresh the display of digital clock after every second. The Font used for the display of clock, is digital-7 which can be downloaded from here.

Sample code of DigitalClock() constructor to use GregorianCalender class to display time using simple java threads.

public DigitalClock() < initComponents(); new Thread()< public void run()< while(true)< Calendar cal=new GregorianCalendar(); int hour=cal.get(Calendar.HOUR); int min=cal.get(Calendar.MINUTE); int sec=cal.get(Calendar.SECOND); int AM_PM=cal.get(Calendar.AM_PM); String Am_Pm=""; if(AM_PM==1)< Am_Pm="PM"; >else < Am_Pm="AM"; >clocklbl.setText(""+hour+":"+min+":"+sec+" "+Am_Pm); > > >.start(); > 

To run the project from the command line, go to the dist folder and type the following:

java -jar "JavaDigitalClock.jar"

Making a digital clock in Java

The approach is to use the date object to get time on every second and then re-rendering time on the browser using the new time that we got by calling the same function each second and to make clocks looks like more attractive. Clocks can be used in sites where time is the main concern like some booking sites or some app showing arriving times of trains, buses, flights, etc.

Making a digital clock in Java

If I understand the question correctly.

You’re working in a OO environment. You should break your design down to the smallest manageable units of work as you can.

For me, this means that each digit (or time unit) is the smallest unit of work. This would require a component that was simply capable of displaying a 0 padded int value.

From there, you could build it up a clock pane, using 3 digit panes as so on.

import java.awt.BorderLayout; import java.awt.Dimension; import java.awt.EventQueue; import java.awt.FontMetrics; import java.awt.Graphics; import java.awt.GridBagLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.util.Calendar; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.Timer; import javax.swing.UIManager; import javax.swing.UnsupportedLookAndFeelException; public class DigitalClock < public static void main(String[] args) < new DigitalClock(); >public DigitalClock() < EventQueue.invokeLater(new Runnable() < @Override public void run() < try < UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); >catch (ClassNotFoundException ex) < >catch (InstantiationException ex) < >catch (IllegalAccessException ex) < >catch (UnsupportedLookAndFeelException ex) < >JFrame frame = new JFrame("Test"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setLayout(new BorderLayout()); frame.add(new TestPane()); frame.pack(); frame.setLocationRelativeTo(null); frame.setVisible(true); > >); > public class TestPane extends JPanel < private DigitPane hour; private DigitPane min; private DigitPane second; private JLabel[] seperator; private int tick = 0; public TestPane() < setLayout(new GridBagLayout()); hour = new DigitPane(); min = new DigitPane(); second = new DigitPane(); seperator = new JLabel[]; add(hour); add(seperator[0]); add(min); add(seperator[1]); add(second); Timer timer = new Timer(500, new ActionListener() < @Override public void actionPerformed(ActionEvent e) < Calendar cal = Calendar.getInstance(); hour.setValue(cal.get(Calendar.HOUR_OF_DAY)); min.setValue(cal.get(Calendar.MINUTE)); second.setValue(cal.get(Calendar.SECOND)); if (tick % 2 == 1) < seperator[0].setText(" "); seperator[1].setText(" "); >else < seperator[0].setText(":"); seperator[1].setText(":"); >tick++; > >); timer.setRepeats(true); timer.setCoalesce(true); timer.start(); > > public class DigitPane extends JPanel < private int value; @Override public Dimension getPreferredSize() < FontMetrics fm = getFontMetrics(getFont()); return new Dimension(fm.stringWidth("00"), fm.getHeight()); >public void setValue(int aValue) < if (value != aValue) < int old = value; value = aValue; firePropertyChange("value", old, value); repaint(); >> public int getValue() < return value; >protected String pad(int value) < StringBuilder sb = new StringBuilder(String.valueOf(value)); while (sb.length() < 2) < sb.insert(0, "0"); >return sb.toString(); > @Override protected void paintComponent(Graphics g) < super.paintComponent(g); String text = pad(getValue()); FontMetrics fm = getFontMetrics(g.getFont()); int x = (getWidth() - fm.stringWidth(text)) / 2; int y = ((getHeight()- fm.getHeight()) / 2) + fm.getAscent(); g.drawString(text, x, y); >> > 

Basically you can do something like.

String min = String.valueOf(Calendar.getInstance().get(Calendar.MINUTE)); char[] digits = min.toCharArray(); 

As shown here, use SimpleDateFormat to format your time. This will give you a formatted string that you can index to get the text for your components.

This related example uses the following formatter:

private static final SimpleDateFormat df = new SimpleDateFormat("HH:mm:ss"); private final Date now = new Date(); . String s = df.format(now);

How to Design Digital Clock using JavaScript, JavaScript Code: For JavaScript, follow the below given steps. Step 1: Create a function “showTime”. Step 2: Create an instance of the Date object. Step 3: Using the methods of Date object get “hours”, “minute” and “seconds”. Step 4: Set AM/PM depending on the hour value.

Design a Digital Clock in Neumorphism Style using JavaScript

A clock is a device that used to measure time. Clocks are a useful element for any UI if used in a proper way. Clocks can be used in sites where time is the main concern like some booking sites or some app showing arriving times of trains, buses, flights, etc. Clock is basically of two types, Analog and Digital. Here, we will design the digital clock and add some styling to make it more attractive.

Approach: The approach is to use the date object to get time on every second and then re-rendering time on the browser using the new time that we got by calling the same function each second and to make clocks looks like more attractive.

HTML & CSS Code: In this section, we have a dummy time in the format of “HH:MM:SS” wrapped inside a “div” tag and we have included the CSS and JavaScript file externally.
