Write a program to display clock using applet

This type of program is used to display the time on browser where your application is running on. The second argument is just a name for the thread. In this example we will see display the time in an applet in the time format like: If you are not familiar with interfaces review the information in the Objects, Classes, and Interfaces lesson.

Applets are not threads, nor do any existing Java-compatible browsers or applet viewers automatically create threads in which to run applets. The Clock applet creates a Thread, clockThread, in its start method and starts the thread.

This tells the main loop in the run method to terminate see the next sectioneventually resulting in the thread stopping and being garbage collected. The applet creates a new thread with this invocation: Thus the first line of the run method loops until clockThread is null.

Clock Applet in Java

Deciding to Use the Runnable Interface The Clock applet uses the Runnable interface to provide the run method for its thread. However, you should not count on this when writing your applets; your applets should create their own threads when doing compute-intensive work.

Some, but not all, browsers create a new thread for every applet to prevent a misbehaved applet from taking over the main browser thread. This method creates a new instance t of the Thread class and starts it.

Java Examples - display a clock using Applet?

If you have not written your own applets before or are not familiar with the life cycle of any applet, you may want to take this time to familiarize yourself with the material in The Life Cycle of an Applet before proceeding with this page.

What is Applet in Java? Within the loop, the applet repaints itself and then tells the Thread to sleep for 1 second milliseconds. Java - Clock Applet in Java Introduction Here is a sample of running clock provided by the java applet to illustrate how to use the clock in an applet.

The Runnable Interface The Clock applet provides a run method for its thread via the Runnable interface. 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. There are three methods have been used in this program to display the current time these are explained below: When constructed in this way, the clock thread gets its run method from its target Runnable object--in this case, the Clock applet.

This program shows the current time. Here is a sample of running clock provided by the java applet to illustrate how to use the clock in an applet.

Write an Applet which display current date and time on the web page??

Here, the ClockApplet is a class name extends from the Applet class and implements to the Runnable interface. The class definition for the Clock class indicates that the Clock is a subclass of Applet and implements the Runnable interface. Otherwise, the applet is already running.

If you revisit the page, the start method is called again, and the clock starts up again with a new thread. If clockThread is null, then the applet has just been loaded or has been previously stopped and a new thread must be created.
