public class KeyValuesTable
extends java.lang.Object

This program is used to load key|values table from a file. The table is stored in a hash table as Hashtable<String, HashSet< String>>. It also eliminates duplicates. This program could be replaced by database File Format: key|value notes: one key could have multiple values from the input file

                                                 java.util.Hashtable<java.lang.String,java.util.HashSet<java.lang.String>> keyValuesTable)

Get sorted unique values for a key in the key-values table.

Parameters:

key - the key for the mapping values

keyValuesTable - the key-values table

Returns:

the sorted unique values for a key in the key-values table.
