Example Java ArrayTable Google Guava

Awesome… that is Word i can say first, for Google Guava Table.

Guava table is a part of library guava. A collection that associates an ordered pair of keys, called a row key and a column key, with a single value. A table may be sparse, with only a small fraction of row key / column key pairs possessing a corresponding value.

The mappings corresponding to a given row key may be viewed as a Map whose keys are the columns. The reverse is also available, associating a column with a row key / value map. Note that, in some implementations, data access by column key may have fewer supported operations or worse performance than data access by row key.
