ASSIGNMENT NUMBER 1 REPORT

1.PROBLEM DESCRIPTION
* Local Times
* Local times of four different cities are to be displayed on the 
   screen concurrently
* Each local time should have the format: hours:minutes:seconds
* Each local time should be updated secondly

Example:
  Ýzmir 19.26.01 19.26.02 19.26.03
  Taipei 25.26.01 25.26.02 25.26.03
  Buenos Aires 14.26.01 14.26.02 14.26.03
  Stockholm 18.26.01 18.26.02 18.26.03

2. SOLUTION IDEA
One program (java applet), which takes name of the city and time zone 
as inputs, is written. The HTML Page will call four instances of this 
program. In the program the system date will be read once in one tenth 
of a second and the screen will be updated if necessary.

3. PROBLEM SOLUTION
In HTML page four instances of java applet must be started. All 
programmes (4) will run as independent processes in a single HTML 
page.

The java applet has different methods. These methos are explained in 
the following paragraphs.

In the initialization part of the program inputs parameters are read 
from the HTML page. 

Paint is the main part of the program. It first read the system clock. 
If the clock is changed the new time has to be displayed. To display
hour, minute, and seconds are parsed from time. The hour of the 
corresponding time zone is calculated. Then the string that will be 
displayed is constructed by concatenating hour, minute, and seconds 
fields of the time. The name of the city is displayed at the top of 
the screen. The time is at the bottom. Before displaying the current 
time the old time has to be erased. To do that the last displayed time
is written again with the background color. 

The start method starts a timer. After an applet is initialized it is 
started. It starts up a thread to control the applet.

Stopping occurs when the reader leaves the page that contains a
currently running applet. Here the stop method stops the timer.

Run method makes the applet to wait for 100 milisecond and then 
repaint the screen if necessary. If one second is waited then we do 
not have synchronisation between the applets. So waiting for less time
to read system date is better solution.

Update method call the paint method.
