CSC 120 Programming Assignment 5

Note:  You should not work on this assignment during lecture or lab class-time unless:
  1. You have completed all of the in-class assigned work for the day, and
  2. You have permission from the instructor.

This assignment must be submitted to the PA5 D2L dropbox before the beginning of class on the due date.

Overview:

Write a Java application that draws a pattern in the output window that is drawn with a for loop, and is drawn in successive stages based on the number of times the user has clicked on a button on screen.  For an example of how your program should work, click here.

Instructions and Requirements:

  1. You should have a for loop in the paintComponent method of MUPanel that will draw one or more shapes, and will be executed howMany times.  You will need some combination of g.setColor, g.drawRect, g.fillRect, g.drawOval, g.fillOval, g.drawArc and/or g.fillArc method calls to draw your assigned pattern.  After the shapes are drawn inside the for loop, the values of the variables over, down, width and/or height may need to be changed, based on how your assigned pattern changes.

  2. Each student in the class has a unique pattern to work on — you MUST use the pattern that has been assigned to you for this project.

  3. Hint:  for this pattern, you will want to set the line width in the paintComponent method to 3.  You can do this by inserting the following two statements in your paintComponent method immediately before the for loop heading: 

            Graphics2D g2d = (Graphics2D) g;
        g2d.setStroke( new BasicStroke(3) );
    See the Changing the Line Thickness Demo for more information.

Turning in your Program for Grading:

Convert your CSC120\Java\PA5 folder into a .zip file named PA5.zip and submit it to the PA5 dropbox in D2L.

Note:  It is expected that each student will complete this assignment INDIVIDUALLY.

One private data member:  an Integer named numberOfReps or something similar. 1
constructor sets numberOfReps to 1. 1
for loop in the paintComponent method that draws one or more shapes, and is executed numberOfReps times. 3
A combination of g. methods used to draw your assigned pattern. 4
After shapes are drawn inside for loop, over, down, width and/or height are changed to make pattern change. 6
One button causes numberOfReps to increase by one.  Other button causes numberOfReps to be reset to 1. 1
Pattern is correctly drawn, and matches the pattern assigned to the student. 8
