  • To run the code examples from class,
    1. go to the directory where the examples are: cd ~csci203/2009-fall/student/wittie/
    2. look at what directories are there: ls
    3. go into the directory you want: (for example) cd introToJava
    4. look at what directories are there: ls
    5. open a file using emacs or gedit: (for example) gedit HelloWorld.java &
    6. compile the files: (for example) javac HellowWorld.java
    7. run the files with the name of the one which has main: (for example) java HellowWorld
  • To import the code examples from class into your eclipse
    1. launch eclipse the usual way
    2. Make a project for class examples
    3. click on that project's name to highlight it
    4. click on the file menu and then import
    5. choose file system (under General) and hit Next
    6. click on Browse
    7. click on accounts from the buttons at the top.
    8. double click on COURSES from the options on the right side
    9. double click on csci203 from the options on the right side (Not cs203, thats an old course)
    10. double click on this semester (2009-fall) and then on student and on wittie
    11. click once on the directory which contains the programs you want (you can double click to go into it but click on wittie at the top to come back out of that directory after you see it).
    12. then click ok
    13. then click on the box next to each file you want. Only select java files, not class files.
    14. click Finish
    15. drag your files into the src directory of your project if they aren't already there.

    Extra Credit

    Each EC assignment is worth .2 added to your overall course grade. Some EC assignments have a specific due date. The rest are due by 5PM on the last day of lecture this semester. Handin using the drop boxes unless otherwise specified. EC is Individual Work (open textbook) unless otherwise specified.
  • Class Survey. Due by 5PM 9/28 for those who missed the first day of class. Hand in during lecture.
  • Do Problems 4,6,8 from the IBM worksheet. Due by 5PM 9/29.
  • Write an IBM program which reads in two 2-digits numbers and adds them. Use the same math process you'd use on paper (add a column, carry any tens to the next column). Display the answer with one digit per box. You can discuss the algorithm for addition (how to add two 2-digit numbers) with anybody you like. Writing the IBM code for it is Individual Work. Due by 5PM 9/29.
  • Draw your own Alien face. It must use a rectangle, an ellipse, a line, a color, and a text string. Due by 5pm on 9/30 (the first exam day). See handout above.
  • We wrote methods for several Stupid Math Tricks in class. There was one more math trick we left undone (about series). Write a method to perform this trick. Due by 5pm on the day of the second exam. The class and the comment for this method can be found in ~csci203/2009-fall/student/wittie/writingMethods/
  • Do the EC from the Stock handout. Due by 5pm on the day of the second exam.
  • DO the Mixed mode math handout. Due by the 2nd exam day.
  • Answer the API questions.
  • Do the last problem on the selection handout. Due by the 2nd exam day.
  • Get the Cannon and Orange game running. Must use selection in both the viewer and the orange. Due by 11/15.
  • Get the combos and secrets working. Due by 11/15. Must use selection with the combo to get EC. Full EC requires that you set compare each digit of the combo seperately. Partial EC also available if you just do a simple string comparison. (Its because the point of this is to write non-simple selection statements).
  • Do the Lottery worksheet. Here is the second data set.
  • Do the Arrays handout and get it running in Eclipse. You will have to write code to instantiate and fill the array.
  • Do the 2D Arrays handout and get it running in Eclipse. Make sure you can play the game.
  • Got some extra free time? Sudoku is a game with a 9x9 grid where the user must place the digits 1..9 so that they occur once in each row, once in each column, and once in each 3x3 box. Read up on this game and then write a program to let someone play Sudoku. Your program must:
    1. Start with some spaces filled and some empty. Use an existing Sudoku game to get your starting numbers.
    2. Print the board with coordinates before each move.
    3. Take input coordinates and a digit from the user.
    4. Make sure the digit is 1..9 (no 0, no 'Q', no 122).
    5. Make sure the coordinates are actually on the board.
    6. Put the digit in the box. Do not let the user overwrite your starting digits. They can overwrite their own digits all they like.
    7. When the board is completely full, tell the user if they have won.
    You must write this code yourself. Cite any websites, newspapers, or books you use for information. I have not given you many game details here so unless you are a die-hard Sudoku player, I expect to see at least 1 cited reference. Worth up to 3 extra credits!!!!
