In the final question, you will write a short class or method according to a textual description. For example, a question might state:

Define a class Dog. A Dog instance has a name (which could change), a breed (which is immutable, that is, it cannot change) and a licenseNumber (an integer between 1 and 1,000,000, which is immutable). Two Doginstances are considered equal if and only if their licenseNumbers are equal.

Your definition should include the constructor and the equals method, but should elide the getters and setters.

Another question might state:

Write a method which, given two int arrays, determines whether the values in the first array a are a subset of the values in the second array b. In other words, return true if and only if every value in a is also present in b. Your method should have the signature boolean isSubset(int[] a, int[] b).
