Write a program which displays changing minutes and seconds, representing them by two long rectangles: make the maximum width of the rectangles equal to 600 pixels to simplify the arithmetic (10 pixels for each minute and each second). Set the size of the frame to 700 pixels wide, and set the preferred width of the drawing panel to 700 pixels. Redraw the two rectangles every second. Figure 6.9 shows a representation of 30 minutes and 15 seconds.

The program should count up in seconds with a timer, and display the total seconds and the time in minutes and seconds. In order to speed up testing the program, you should reduce the timer interval from 1000 milliseconds to, say, 200.
