Accumulate

Accumulate 1.3 Description

Used to accumulate values by category. It might be useful
for example in a billing program to accumulate hours by
various categories.

It could be used to count how many times various words
occurred in a document.

All you need is:

buckets.accumulate( "somecategory", someamount );

And Accumulate looks after creating the buckets to
accumulate new categories for you.

e.g.

Accumulate buckets = new Accumulate( 20 );
buckets.accumulate( "ugli fruit", 3 );
buckets.accumulate( "peaches", 10 );
buckets.accumulate( "strawberries", 15 );
buckets.accumulate( "peaches", 14 );
String[] categories = buckets.categories();

// prints:
// peaches:24
// strawberries:15
// ugli fruit:3
for (String category: categories )
{
System.out.println( category:
+ ":"
+ buckets.total( category ));
}

You can test the app with:
