filter and sort list using google collections

Question

Suppose I have a list (or Set):

List testList = Lists.newArrayList(\"assocX\",\"srcT\",\"destA\",\"srcX\", \"don\'t care Y\", \"garbage\", \"sr         


        

Answer 1

Have a look at This Google Collections example.

Function getNameFunction = new Function() {
    public String apply(Fruit from) {
        return from.getName();
    }
};

Ordering nameOrdering = Ordering.natural().onResultOf(getNameFunction);

ImmutableSortedSet sortedFruits = ImmutableSortedSet.orderedBy(
    nameOrdering).addAll(fruits).build();

Though this, admittedly, returns a Set.
