Emailing Programs Instead of Paper Submission

Looks like all the tree huggers in the class would rather submit their screen shots by email than paper copies. That is ok with me. Some of the ones I have received, however, are illegible. Please try to increase the font size on your screen before taking the picture if possible.

Incorrent Answer to Juno Problem

One of the problems in tonight's juno assignment had the wrong answer. The question was, "Which detects syntax errors." The right answer is the compiler, not the operating system. This has been fixed.

Video Describing How to Build "Hello World" Program


This video which is on youtube is well suited to help you get started with your hello world program if you need extra help.

Mr. Sarkar

How to Build and Run "Hello, world" Program

There was not much time at the end of class so I rushed through the process of how to write your first program. I'm adding some additional  instructions here. But you are encouraged to go on youtube and find some videos to help you as well.


  1. double click on the BlueJ icon to launch BlueJ
  2. click on Project and open a new project
  3. enter a file name for your project (maybe call it "Project 1")
  4. BlueJ window should now be open
  5. click on New Class to create a new class
  6. enter "Hello"
  7. double click on the Hello box in BlueJ 
  8. you should now see the code for Hello
  9. replace all the code in this window with what i showed in class.
  10. hit the compile button
  11. return to the main BlueJ window, right mouse click on the Hello box and select main()
  12. when it asks for args, just hit OK
  13. you should see Hello World printed on the console window
I promise to go over this in class step by step tomorrow as well.

Just a gentle reminder that summer is almost over. So if you have been procrastinating on your summer packet for AP Computer Science, now would be a good time to get going. Looking forward to seeing all of you in three weeks!
