Computer Science 15-111 (Sec A+B), Spring 2007

Homework #1

Due: Wed 17-Jan-2007 as you enter class.

1. Installation

Install Java and Eclipse on your primary computer in their entirety as described on today's "Class Notes" handout. What to submit: A statement saying "I did it!" or, if you did not do it, a statement saying "I did NOT do it" along with a brief explanation as to why not (for example, "because I do not plan to use my own computer for this course"). Note that Java 1.5 and Eclipse are installed on all the lab computers, so everyone is assumed to have adequate access at all times -- in particular, starting with the next assignment.

2. Intro to "The Java Tutorial": Hello World!

A. Go to "The Big Picture", scroll to the bottom, click on "The Java Tutorial" (or go directly to: http://java.sun.com/docs/books/tutorial/index.html).

B. Read the entire "Getting Started" trail (though you may skip Gosling and McGilton's white paper and all the material referring to NetBeans).

C. Following the instructions, create and execute "Hello World" through the command line (Windows or Solaris, your choice).

D. Complete the "Questions and Exercises"

E. Check your answers (!).

3. Intro to Eclipse: Hello World!

A. Run Eclipse (again, see the Eclipse readme file if necessary).

B. Go To the Welcome Screen (either at startup or via the "Help" menu)

C. Select the "Tutorials" icon, then "Create a Hello World Application"

D. Follow the step-by-step instructions at the right, EXCEPT: For the last step, do not follow the instructions. Instead, click on the green right-arrow (labeled "Run"), double-click on "Java Application" and again on "Hello World".

E. As with question #1, simply indicate that you were able to make Eclipse work for you (and, if not, why not). If you have problems, though, you must contact a CA prior to class on Wednesday to work through the difficulties.

4. Intro to "Demos, Samples, Tutorials, Training and Reference"

This is not required, but it is highly recommended that you spend some time drifting through the various materials under the "Demos, Samples, Tutorials, Training and Reference" heading on "The Big Picture" page. There is far more here than you can digest at once, but it's good to start to know what resources are available to you here.

What to Submit:

A hardcopy (just this once!), labelled "15-111 hw 1", with your name, section, and CA's name all clearly denoted at the top of the page. Below this, your responses to #1 (Installation), #2D, and #3. Note: if you do not have success with some part of this assignment, you must contact your CA prior to class Wednesday (preferably today or tomorrow) to work through the obstacles. Plainly, a working Java and Eclipse (or other IDE) installation is absolutely essential in order to complete all future homework assignments in this class, such as the one that will be assigned on Wednesday and due on Friday!
