Analog Clock

Hello friends, we are going to make an Analog Clock in this project. Open your IntelliJ or any other IDE and create a new Project. Now, name this project whatever you likes and go to Main.java file.

Now, write the following code in Main.java file.

Main.java :

import javax.swing.*;
import java.awt.*;


public class Main {
  public static int height = 600;
  public static int width = 600;

  public static void main(String[] args) {
    JFrame obj = new JFrame();
    Analog analog = new Analog();

    obj.setBounds(100,100,width,height);
    obj.setTitle("Clock");
    obj.setBackground(Color.BLACK);
    obj.setResizable(false);
    obj.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    obj.add(analog);
    obj.setVisible(true);
  }
}

Now, go to Projects tab.
Right Click on src folder, go to New and Click on JAVA Class.
Name the new JAVA Class as Analog.java
Write the following code in Analog.java.

Analog.java :

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Calendar;


public class Analog extends JPanel {
  int x, y;
  double angle;
  public int interval = 1000;
  public Timer timer;

  public Analog() {
    timer = new Timer(interval, new TimerAction());
    timer.start();
  }

  class TimerAction implements ActionListener {
    public void actionPerformed(ActionEvent e) {
      repaint();
    }
  }

  public void paint(Graphics g) {
    Calendar time = Calendar.getInstance();

    int hour = time.get(Calendar.HOUR_OF_DAY);
    int minute = time.get(Calendar.MINUTE);
    int second = time.get(Calendar.SECOND);

    if (hour > 12) {
      hour -= 12;
    }

    g.setColor(Color.WHITE);
    g.fillOval(100, 100, 400, 400);

    g.setColor(Color.BLACK);
    g.drawString("12", 294, 120);
    g.drawString("9", 120, 304);
    g.drawString("6", 297, 480);
    g.drawString("3", 480, 304);{

    angle = Math.toRadians((15 - second) * 6);

    x = (int)(Math.cos(angle) * 200);
    y = (int)(Math.sin(angle) * 200);

    g.setColor(Color.RED);
    g.drawLine(300, 300, 300 + x, 300 - y);

    angle = Math.toRadians((15 - minute) * 6);

    x = (int)(Math.cos(angle) * 150);
    y = (int)(Math.sin(angle) * 150);

    g.setColor(Color.BLUE);
    g.drawLine(300, 300, 300 + x, 300 - y);

    angle = Math.toRadians((15 - (hour * 5)) * 6);

    x = (int)(Math.cos(angle) * 100);
    y = (int)(Math.sin(angle) * 100);

    g.setColor(Color.BLACK);
    g.drawLine(300, 300, 300 + x, 300 - y);
    }
  }
}
