Analog Clock program in java

1]. Seconds hand completes 360 degrees in 1 minute.
2]. Minute hand completes 360 degrees in 1 hour.
3]. Hour hand completes 360 degrees in 12 hours.
4]. Set of points traced by circle is given by :
                                                        x=cx+r*angle; y=cy+r*angle;
# (cx,cy)=coordinates of centre of circle.
# r= radius.
                                      => i.e path traced by minute and seconds hands in same.

                                      =>Where as hour hand cover 5 degrees when minute hand sweeps 360 degrees.(360/5=12 used in looping).

                                                                                      ......................HAPPY CODING

Photo Application in java

                             Photo Application in java

1]. Import different photos which you want in photo application.

2]. Place photo name in function getImage(getCodeBase(), "acura.jpg"). where photo name                       is acura.jpg.

3]. Don't forget to add extensions like jpg  to your photo name.

                                                                               ............Happy Coding
