This article will provide an instance of creating one type of stopwatch with Java Applet, AWT and Thread.
We shall be using all these library to make a working model of a stopwatch. The GUI shall have 3 buttons for interaction, namely, start (to start the time), reset (to reset the time to default value) and stop (to stop the timer).
With the help of actionListener in Java we can learn which button is pressed when.
- When the start button is pressed, we start the timer. While the reset or the stop button isn’t pressed we shall keep the timer running i.e. we shall change the value of the timer (hh:mm:ss:ms) every 1 millisecond and update the screen.
- When reset button is pressed, we shall stop the timer and set it to is default value (00:00:00:000).
- When the stop button is pressed, we stop the timer with the value as it is.
Below is the implementation of Digital Stopwatch
