Accumulate

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:
