I\'ve got a class, \"Accumulator\", that implements the Comparable compareTo method, and I\'m trying to put these objects into a HashSet.
If I have a list of elements I would like to sort, Java offers two ways to go about this. For example, lets say I have a list of Movie objects and I’d like to sort them by title.
Comparable contract specifies that e.compareTo(null) must throw NullPointerException. From the API: Note that null is not an instance of any class, and e.compareTo(null) should throw a NullPointerE
For a class assignment, we can\'t use any of the languages bultin types, so I\'m stuck with my own list. Anyway, here\'s the situation:
I\'m want a IDictionary<float, foo> that returns the larges values of the key first. private IDictionary<float, foo> layers = new SortedDictionary<float, foo>(new DescendingComparer
When implementing compareTo(), does the degree of \"difference\" need to be taken into account? 开发者_如何学GoFor instance, if I have 3 objects, C1, C2, and C3, such that C1 < C2 < C3.
I have a list of objects I need to sort on a field, say Score. Without giving much thought I wrote a new class that implements Comparator, that does the task and it works.
