What is the Java interface that I need to implement to allow the Java Collections Framework to sort my collection?
- I really like my mother’s cooking, but I don’t like my brother’s cooking as much. My mother spends a lot more on ingredients than my brother does.
I decide to write a class to create objects that have 2 fields:
- An int with a range 1-10 that is a rating of how much I like a particular
- A double to hold the cost of the ingredients for the meal.
I have created a mathematical formula that computes my total happiness with the meal, based upon how much I like it, and how affordable it is.
I want to be able to sort the collection of objects (meals) based upon this formula, so that I can always request the meal that gives me the most happiness. But I want to put my most recent meal at the back of the list.
The data structure that I use to store the meals is not necessarily a list.
I may have a data structure like a type of queue, a priority queue, that stores all of the meals, and puts the most recently eaten meal back to the beginning of the queue.
