Problem Set Four

Second Summer 2000

Your problem will be randomly distributed to you by logging in to QuizSite. Due date is Fri Jul 7 11:59pm. Solutions to be posted here Saturday July 8, at noon.

1. Write a graphics program that draws your name in red, centered inside a blue rectangle.

2. Write a graphics program that draws your name four times, in a large serif font, in plain, bold, italic, and bold italic. The names should be stacked on top of each other, with equal distance between them. Each of them should be centered horizontally, and the entire stack should be centered vertically.
3. Write a graphics program that draws twelve strings, one each for the 12 standard colors beside Color.white, each in its own color.
4. Write a graphics program that prompts the user to enter a radius. Draw a circle with that radius.
5. Write a program that draws two solid circles, one in pink and one in purple. Use a standard color for one of them and a custom color for the other.
6. Draw a "bull's eye" -- a set of concentric rings in alternating red and white colors. Hint: Fill a red circle, then fill a smaller white circle on top, and so on.

7. Write a program that fills the applet window with a large ellipse, filled with your favourite color, that touches the window boundaries. The ellipse should resize itself when you resize the window.
8. Write a program that draws the picture of a house. It could be as simple as the figure below, or if you like, make it more elaborate (3-D, skyscraper, marble columns in the entryway, whatever).

9. Write a program to plot the following face.

10. Write a program to plot the string "HELLO," using just lines and circles. Do not call drawString, and do not use System.out.
11. Plotting a data set. Make a bar chart to plot the following data set:

Bridge Name Longest Span (ft)
Golden Gate 4,200
Brooklyn 1,595
Delaware Memorial 2,150
Mackinac 3,800

Make the bars horizontal for easier labeling. Hint: Set the window coordinates to 5,000 in the x-direction and 4 in the y-direction.

12. Write a graphics program that displays the values of exercise 4.11 as a pie chart.
13. Write a program that displays the Olympic rings.

Make the rings colored in the Olympic colors.

14. Write a graphics program that draws a clock face with a time that the user enters in a text fiels. (The user must enter the time in the format hh:mm, for example 09:45).

Hint: You need to find out the angles of the hour hand and the minute hand. The angle of the minute hand is easy: The minute hand travels 360 degrees in 60 minutes. The angle of the hour hand is harder; it travels 360 degrees in 12 x 60 minutes.

15. Change the CarDrawer program to make the car appear twice the size of the original example.
16. Design a class Car whose constructor takes the top left corner point of the car. Supply a method 
draw(Graphics2D g2)
that draws the car. Then populate your screen with a few cars.
17. Extend Exercise 4.8 by implementing a class House. In the constructor of the House class, supply the bottom left corner of the house and its width and height. Supply a method 
draw(Graphics2D g2)
that draws the house. Then populate your screen with a few houses of different sizes.
