Part 1 Understand the Problem and Class Design with UML

• The client needs a program to calculate the age of a tuna fish. The program must store the length of the fish in cm, and the weight of the fish in pounds. To calculate the estimated age of the fish in years multiply the length times the weight then divide by 10000. Design a class based on this word problem.

• Testing values are 300 cm length, and 1111.12 pounds.

• Using the word problem above, design a class with the needed fields, one default (no parameter) constructor, and needed methods. Document your design using a detailed UML Class diagram.

• Note: The calculations used in this word problem are fictional.

Part 2 Write the Java code for the class

• Follow your UML class diagram and code the class you designed.
• Use Java coding conventions for identifiers: class, constructor, field, variable, and method names
• Mark fields private, constructor and methods public.
• Select and use appropriate data types for the fields as well as method parameters as needed.
• Comment your code as requested and demonstrated in the course.

Problem 2.55. Consider the dihedral group D3 introduced in Problem 2.21. To give us a common starting point, let’s assume the triangle and hole are positioned so that one of the tips of the triangle is pointed up. Let r be rotation by 120◦ in the clockwise direction and let s be the reflection in D3 that fixes the top of the triangle.

(a) Describe the action of r −1 on the triangle and express r −1 as a word using r only.

(b) Describe the action of s −1 on the triangle and express s −1 as a word using s only.
(c) Prove that D3 = hr, si by writing every element of D3 as a word in r or s.

(d) Is {r, s} a minimal generating set for D3 ?

(e) Explain why there is no single generating set for D3 consisting of a single element. This proves that D3 is not cyclic.

It is important to point out that the fact that {r, s} is a minimal generating set for D3 does not imply that D3 is not a cyclic group. There are examples of cyclic groups that have minimal generating sets consisting of more than one element (see Problem 2.70).
