PROGRAMMING ASSIGNMENT 1
Description
This program tests your understanding of using static methods and println statements. You
should write a Java class called ThisHouse that must be saved into a file called
ThisHouse.java. Your program should produce the following nursery rhyme as output:
This is the house that Jack built.
This is the malt
That lay in the house that Jack built.
This is the rat,
That ate the malt
That lay in the house that Jack built.
This is the cat,
That killed the rat,
That ate the malt
That lay in the house that Jack built.
This is the dog,
That worried the cat,
That killed the rat,
That ate the malt
That lay in the house that Jack built.
This is the cow with the crumpled horn,
That tossed the dog,
That worried the cat,
That killed the rat,
That ate the malt
That lay in the house that Jack built.
This is the maiden all forlorn
That milked the cow with the crumpled horn,
That tossed the dog,
That worried the cat,
That killed the rat,
That ate the malt
That lay in the house that Jack built.
The output is the first seven verses of the nursery rhyme “This is the house that Jack built” by
Mother Goose. You should exactly reproduce the format of this output. This includes having
identical wording, spelling, spacing, punctuation, and capitalization. Please do not include
additional verses, such as writing eleven verses to match the complete nursery rhyme. You may
include blank lines at the very end of the output if you like. One way to write this program would
be to simply write a println statement that outputs each line of the rhyme in order. However,
such a solution would not receive full credit. Part of the challenge of this assignment lies in
recognizing the structure and redundancy of the rhyme and improving the code using static
methods.
Stylistic+Guidelines:
Any println statement that prints text should not be in your main method. Instead, use static
methods in this program, for two reasons:
1. To capture the structure of the rhyme’s seven verses.
You should be using static methods to capture the structure of the rhyme. You should, for
example, have a method for each of the seven verses of the rhyme to print that verse's
entire contents. You can write additional methods as you see fit.
2. To avoid simple redundancy in the output.
You should use only one println statement for each distinct non-blank line of the
rhyme. For example, the following line appears several times in the output, but you
should have only one println statement in your program that prints that line of the
rhyme:
That lay in the house that Jack built.
However, a method that prints a single line such as the above is not useful. Instead, you should
identify groups of two or more lines that appear in multiple places in the rhyme and create static
methods that capture those groups and are called multiple times. There is a general structural
redundancy to the rhyme that you should eliminate with your static methods. Recall that methods
can call other methods if necessary. The key question to ask yourself is whether or not you have
repeated lines of code that could be eliminated if you structured your static methods differently.
For this assignment, you should limit yourself to the Java features covered in class so far
(Lecture 1- Lecture 4).
Submission+and+Grading:
Turn in your ThisHouse.java file electronically via Latte by the day it is due, Thursday,
September 8 at 11:00pm. Please make sure to use exactly this file name, including identical
capitalization.
Part of your program's score will come from its "external correctness." External correctness
measures whether the output matches exactly what is expected. (We are very picky about the
output matching exactly. Every character and space must match.) Programs that do not compile
will receive no external correctness points. The rest of your program's score will come from its
"internal correctness." Internal correctness measures whether your source code follows the
stylistic guidelines specified in this document. This includes having an adequate comment header
and capturing the structure and redundancy of the rhyme as specified previously.
