Class JbbHistogram<V>

java.lang.Object
  com.quadrique.jbuildingblocks.core.dataStructure.JbbHistogram<V>

Type Parameters:

V - the datatype for the Values

public class JbbHistogram<V>
extends Object

The histogram of a given set of input values is a list of buckets where each bucket contains one of the input values and its associated number of occurences in the set.

For instance:

Histogram<Integer> histogram = new Histogram<Integer>();
histogram.add(1);
histogram.add(2);
histogram.add(3);
histogram.add(2);
histogram.add(2);
System.out.println("The number of buckets is: " + histogram.getNbOfBuckets());
ArrayList> list = histogram.getAllBuckets();
System.out.println("The buckets are: ");
for (HistogramBucket b : list)
{
System.out.println(b);
}

The corresponding execution results are:

The number of buckets is: 3
The buckets are:
Value: "2", Number of occurences: 3
Value: "1", Number of occurences: 1
Value: "3", Number of occurences: 1
