Assistance in having a java program which, given three sides of a triangle, determines whether the triangle is:
1. Equilateral - all sides the same length,
2. Isosceles - two sides the same length or
3. Scalene - no sides the same length
The details of the problem are enclosed here with in two different formats.
Produce a Java program which, given three sides of a triangle,
determines whether the triangle is:
1. Equilateral - all sides the same length,
2. Isosceles - two sides the same length or
3. Scalene - no sides the same length
(see Figure 1). Assume that any individual side must be a positive
number not greater than 100.0.
Also use an appropriate loop to allow the user to repeat the above
actions until they choose to exit the program.
Remember to write the source code for each class in a separate file
which must have the same name as the class name together with the
extension .java. Remember also that by convention, class names commence
with a capital letter.
As with all programs you write, you should provide a well-structured
solution that is easy to read. You should use meaningful identifier
names and should provide useful comments. We need to high-light the
structure of our classes, not whether they do or don't work correctly.

marks for this assignment will be based on the structure of your
classes, not whether they do or don't work correctly.
The focus of the assignment is for you to familiarise yourself with the
Java concepts introduced in this seminar (selection statements and
loops). If you have difficulty with the assignment, you may discuss
these problems in the discussion folder as long as you do not directly
discuss the assignment problems.
In the event of compilation problems (i.e. your program will not
compile), do not post entire classes and ask what is wrong with them.
This would violate the above stricture of not discussing the assignment
problems in the main folder. Instead, try and identify the source of
the problem through a process of elimination (by commenting out chunks
of the code). You may discuss error messages you may receive, you may
discuss compilation problems with the Smiley Face, selection statement
and looping applications found in the lecture, and perhaps these
discussions will help you to figure out where your errors lie. In
addition, you may always contact me via private e-mail if you are having
a specific problem and none of the above solutions seem to work for you.
Please use this option as a last resort, however!
It is a good idea to work in a step-by-step top-down manner. For
example, first define the general structure of a class with empty
methods and compile the file. Once it compiles successfully, then start
adding further detail, recompiling after every few lines. This way, the
risk of getting a screen full of error messages is reduced, and you can
be assured of handing in something that works by the end of the week.
