Everyone starts with a grade point of zero for this assignment. Implementing each of the features below completely and correctly will award you 1.0 grade points (i.e. implementing all four features will result in a grade point of 4.0 being awarded).

• When the program runs it will create a JFrame containing a JButton the latter with some default text (Figure 1): worth 1 letter step
• When the button is pressed two things will happen:
  1. The text of the button changes to a non-default value (Figure 2): worth 1 letter step
  2. Another JFrame window appears that contains the same non-default text contained in the button (Figure 3): worth 1 letter step
• The close behavior for both (no credit if you change one but not the other) JFrames (triggered when the close window control is clicked: Figure 4) is changed from hiding the window to the disposal of the control: worth 1 letter step

Figure 1: Program initially run, JFrame contains a JButton with default text

Figure 2: Button pressed: the text of the button changes to a non-default value

Figure 3: Button pressed: a new  JFrame popup (containing the same non-default text from the button) appears for each press

Figure 4: Clicking on the close window control (top right of the JFrame) will 'dispose' of the control (rather than default 'hide' behavior)

Points to keep in mind:

1. Due time: All assignments are due at 4 PM on the due dates listed on the course web page.  Late assignments or components of assignments will not be accepted for marking without approval for an extension beforehand. What you have submitted in D2L as of the due date is what will be marked.
2. Extensions may be granted for reasonable cases by the course instructor with the receipt of the appropriate documentation (e.g., a doctor's note). Typical examples of reasonable cases for an extension include: illness or a death in the family. Cases where extensions will not be granted include situations that are typical of student life: having multiple due dates, work commitments etc. Tutorial instructors (TA's) will not be able to provide extension on their own and must receive permission from the course instructor first. (Note: Forgetting to hand your assignment or a component of your assignment in does not constitute a sufficient reason for handing your assignment late).
3. Method of submission: You are to submit your assignment using D2L [help link]. Make sure that you [check the contents of your submitted files] (e.g., is the file okay or was it corrupted, is it the correct version etc.). It's your responsibility to do this! (Make sure that your submit your assignment with enough time before it comes due for you to do a check).
4. Identifying information: All assignments should include contact information (full name and student ID number) at the very top of your program in the class where the 'main()' function/method resides.
5. Collaboration: Assignments must reflect individual work, group work is not allowed in this class nor can you copy the work of others.  For more detailed information as to what constitutes academic misconduct (i.e., cheating) for this course please read the following [link].
6. Execution: programs must run on the computer science network.  If you write you code in the lab and work remotely using a remote login program such as Putty or SSH. If you choose to install Java on your own computer then it is your responsibility to ensure that your program will run properly here. It's not recommended that you use an IDE for writing your programs but if you use one then make sure that you submit your program in the form of individual text ".java" files (one for each class that you define).
7. Source code: in order to get any credit for your work you must submit all relevant dot-java files for the assignment (e.g., Driver.java). If you only submit your byte code files (e.g. Driver.class) then you will not be awarded any credit.

D2L configuration for this course

• You can (and really should) submit work as many times as you wish before the due date
• D2L will only retain whatever files that you submitted the last time that you uploaded to D2L, previous files will not be retained (e.g. if you submit files: A.java, B.java, C.jpg the first time and then you submit A.java the second time then D2L will only have one file stored: A.java. That means that you should submit every file associated with the assignment each time that you want to submit something regardless of how many of those files were actually changed since the last submission.
