Homework Assignment 4

Due: 9am, November 10, 2008.

This assignment will give you practice at writing Java program that contain:

• Simple branching (e.g., if-else) and looping constructs.
• One- and two-dimensional arrays.

Solve problems 9, 12, 15, 16, 17 and 18 in the Java Programming Exercises.

A few hints. Most of what you need can be found on the "java examples" web page and in the blue class reader:

• Solutions to a number of the problems in "java exercises" can be found in the class reader. You should look at them to see how your program should be structured, what packages need to be included, and so forth.

Note. For each problem, hand in a copy of your program source code and a script of I/O for typical program usage.

If you are working on UNIX/Mac OS X then the procedure for creating a script is easy -- just type something like:

    prompt >> script output-file

Now all input/output on the screen will be echoed to the file "output-file". To terminate the script, type:

    prompt >> exit

Now print "output-file" and hand it in.

If you are working on Windows, just cut-and-paste the output into a Word document.
