COM6471 Assignment 1: Simple Formatting
Dr Ramsay G Taylor
October 5, 2018
1 Outline
This is the first assignment for COM6471 Foundations of Object Oriented Programming,
worth 10% of your final module mark. This is a relatively simple
assignment and is intended to introduce you to producing Java code in a form
that can be submitted, and that can be understood and used by other people.
The specific tasks are described in Section 2, but the objective is to do some
simple text formatting. Figure 1 shows a raw text file with multiple lines, some
of which are Chapter headings, some are Section headings, and some are plain
text rows. There is no formatting to this text file, its just lines of text.
A slightly more beautiful format is shown in Figure 2. In this format:
Every line that starts with “Chapter” is preceded by two blank lines.
Every line that starts with “Section” is preceded by one blank line, and
is indented by either one tab character or four space characters.
Every line that doesn’t start with either “Chapter” or “Section” is indented
by two tab characters or eight space characters.
This is what we want you to produce with your program.

2 Task
You should produce a single Java Class with a single main method, with the
following behaviour:
1. When the Java program is run it should take one argument at the command
line, which is the name of the input file.
2. You should open that file and begin to read lines.
3. You should print each line to the standard output in the form shown in
Figure 2, and add blank lines and tab/space characters as described above.
4. You should do this for every transaction in the file.
Some things to consider:
You can use the EasyReader class to read files.
You can use the EasyWriter class to help format the output.
The file may contain one or more blank lines.
You are expected to present your code in a helpful and professional way —
this includes sensible layout, helpful and conventional choices for variable
names, and some comments to describe the main method overall, and at
a few places in the code to explain what is going on.
3 Submission and Marking
You should submit your .java files through MOLE. You should upload the
.java file that contains your code.
The marking scheme will be as follows:
70 — 100% A program that produces almost exactly the desired output,
and code that is clean and clear and commented.
60 — 70 A program that runs and produces something approximating
the required output. Some comments and sensible layout
and naming.
50 — 60 A class with a main method that compiles and runs. At
least fairly readable code.
40 — 50 A basic class and main method with some mistakes that
stop it compiling, but some evidence that you understand
what you are doing.
0 — 40 Credit given for whatever is present.
You should notice that this mark scheme is only partially about whether
or not the code works and produces the desired output. At least some of the
4
marks are for having code that is readable and clear and well formatted. Code
blocks within methods and within if and while statements should be indented.
Variables should have descriptive names. There should be a few comments
around significant sections of the code to explain what they are doing. There
isn’t a specific coding standard but you will be penalised for confusing or messy
code.
You are reminded that the University of Sheffield takes the use of
unfair means very seriously. The code you present for this assignment must
be entirely your own work. Code that is plagiarised — that is, copied from
somewhere else — is not acceptable and you will receive zero for this assignment
and be called to a departmental unfair means panel where it will be investigated
further.http://www.daixie0.com/contents/9/1843.html
Since the purpose of these assignments is to test your knowledge of Object
Oriented design and Java, you must also avoid collusion — that is, discussing
your design or implementation with your classmates to such a degree that you
end up submitting similar work. Even if you have produced the code independently,
part of the object of the assignment is to evaluate your Object Oriented
design approach, so you must develop your solution independently.
