handout #5
CSE142—Computer Programming I
Programming Assignment #1
due: Wednesday,
Your first program will require the use of
static methods and println statements. This is assignment is worth 10 points instead
of the normal 20 points. You are going
to write a Java program that produces as output the following song.
There was an old woman who
swallowed a fly.
I don't know why she swallowed
that fly,
Perhaps she'll die.
There was an old woman who swallowed a spider,
That wriggled and iggled and jiggled insider her.
She swallowed the spider to
catch the fly,
I don't know why she swallowed
that fly,
Perhaps she'll die.
There was an old woman who swallowed a bird,
How absurd to swallow a bird.
She swallowed the bird to catch
the spider,
She swallowed the spider to
catch the fly,
I don't know why she swallowed
that fly,
Perhaps she'll die.
There was an old woman who swallowed a cat,
Imagine that to swallow a cat.
She swallowed the cat to catch
the bird,
She swallowed the bird to catch
the spider,
She swallowed the spider to
catch the fly,
I don't know why she swallowed
that fly,
Perhaps she'll die.
There was an old woman who swallowed a dog,
What a hog to swallow a dog.
She swallowed the dog to catch
the cat,
She swallowed the cat to catch
the bird,
She swallowed the bird to catch
the spider,
She swallowed the spider to
catch the fly,
I don't know why she swallowed
that fly,
Perhaps she'll die.
There was an old woman who swallowed a horse,
She died of course.
You must exactly reproduce the format of this
output, although you are allowed to have an extra blank line after the “She
died” line if it makes your program easier to write.
You are to make use of
static methods to avoid the "simple" redundancy. In particular, you are to make sure that you
use only one println statement for each distinct line
of the song. For example, this line:
Perhaps she'll die.
appears several times in the
output. You are to have only one println statement in your program for producing this
line. The more complex redundancy has to
do with pairs of lines like these
There was an old woman
who swallowed a horse,
There was an old woman who swallowed a dog,
and like these
She swallowed the dog to eat the
cat,
She swallowed the cat to eat the
bird,
It is not possible to avoid this redundancy
using just methods and simple println statements, so
you are not expected to do so.
You should also be using static methods to
capture the structure of the song. You
should, for example, have a different method for each verse of the song.
You should include a comment at the beginning of
your program with some basic
information and a description of the program, as in:
// Stuart Reges
// 10/1/04
// CSE142
// TA: George Bush
// Assignment #1

You should name your file Song.java
and you should turn it in electronically.
There will be instructions linked from the “assignments”
link on the class web page.
