Here is a sample of running clock provided by the java applet to illustrate how to use the clock in an applet. This program shows the current time. This type of program is used to display the time on browser where your application is running on.
In this example we will see display the time in an applet in the time format like: hours, minutes and then seconds (hh:mm:ss). Here, the ClockApplet is a class name extends from the Applet class and implements to the Runnable interface. There are two threads used in this program. There are three methods have been used in this program to display the current time these are explained below :
This is the start() method used in this program. This method creates a new instance t of the Thread class and starts it.
This is the run() method which uses the Runnable interface. This method creates another Thread instance t1 and starts it. In this method the repaint() method has also been used to paint the applet viewer with it's objects again and again during the 1 second(1000 millisecond).
This is the paint() method which prints all the things in applet viewer or a browser.
In this program sleep() method of the thread has been used to set the time interval of 1 minute and repaint() method has been used to call the pain() method.
Here is the code of the program :
Here is the HTML code :
<APPLET CODE = "ClockApplet" WIDTH = "500" HEIGHT = "400"></APPLET>
