Java Applet | How to display a Digital Clock
In this article, we shall be animating the applet window with a 1-second delay. The idea is to display the system time of every instance.
Here 6 seven-segment displays are created using the Java Applet library to print the system time in HH:MM:SS format. Each segment of the seven-segment display, numbered as follows can be lit in different combinations to represent the numbers 0-9.
We have 6 seven-segment display for displaying the time in HH:MM:SS pattern. Each segment numbered as the following can be lit in different combinations to represent the numbers 0-9.
We can assume every single segment as 1 bit so (0-9) 10 number can make 10 different combinations.
e.g. if we want to display 0 we should lit-up the segments 0, 1, 2, 3, 4, 5. So this combination will make the number (2^0 | 2^1 | 2^2 | 2^3 | 2^4 | 2^5) = 63.
Below is the implementation of the above approach:
