mathCollection is a Java package representing a consistent and efficient extension to the Java Collection Framework of JDK 1.4 that adds the handling of mathematical sets, sets of sets and multisets (bags). There is also a special class for mathematical sets of integer values. Mathematical sets implement usual mathematical functions for sets in an non-destructive way, sets of sets have sets as elements and multisets count the frequency of each element in the collection. For more information, look at the documentation of the package.
The package was included in the Java Bug Database under Bug Id 4938537.
