Homework Assignment 3

Due: 9am, April 13, 2007.

This assignment will give you practice at writing Java programs where:

Input is read from the keyboard, and
Branching and looping constructs are used in the solution of simple engineering problems.
A one dimensional array is used to store rainfall measurements.
The mean and standard deviation of data in an array is computed in separate methods.

Write Java programs to solve Problems 3, 7, 12, 15 and 17. in the Java Exercises Handout (see the purple book).

Hint. Most of what you need can be found on the "java examples" web page and in the purple class reader:

In past years, we have employed the method keyboardInput() to read input typed at the keyboard. Now that Java 5 is available, you should replace the method keyboardInput() with getTextFromConsole().
Solutions to a number of the problems in "java exercises" can be found in the purple book. 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. To create a script, 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.
