AIM:
To write a java
program for real-time program for implementing an alarm clock shall be
developed
ALGORITHM:
Step 1:
Start the program
Step 2:
Display init is used for initialization, and shall be
called from the main function of the program.
Step 3:
Before
the processes are created.
Step 4:
Display
time displays the current time, and shall be called by the clock process
Step 5:
Display
alarm time shows the current alarm time, and shall be called when a new alarm
time is set.
Step 6:
Erase
alarm time erases the displayed alarm time, and shall be called when the user
acknowledges an alarm
Step 7:
Display
alarm text is used to show an alarm activation, and shall be called when the
user shall be informed that the alarm has been activated
Step 8:
When the
alarm is activated the first time, and when the alarm is activated repeatedly
(which is every 10 seconds, according to the above stated requirements).
Step 9:
End of
programs
