Instructions
A farmer has an ArrayList of Pigs (fat pigs, if you are wondering). He wants to be able to sort the pigs by Welght and Age. He is a smart man and will not reinvent the wheel by writing a sorting algorithm. He knows that he can sort his ArrayList using the
Collections.sort() static method.
The problem is that Java is not that clever. Although Java knows the sorting algorithm it does not know how to compare two pigs =/
Your job is to help the farmer by implementing the Comparable interface (type-safe, we talked (will talk) about in Lecture 14) in the Pigs class. Plgs should be compared by welght ("smallest" first). If both plgs have the same welght, then compare them by
age (youngest first).
The starter code wll not compile until you implement the Comparable interface on the Pig class. You can/should play with the implementation of comparable to see how it affects the sorting.
