public static final int calcCapacity(int size)
size elements in
a HashMap or Hashtable without forcing an expensive increase in internal
capacity. Capacity is based on the default load factor of .75.
Usage: Map map = new HashMap(HashMapUtils.calcCapacity(10));
size - the number of items that will be put into a HashMap
public static java.util.HashMap merge(java.util.Map map1,
java.util.Map map2)
HashMap that has all of the elements
of map1 and map2 (on key collision, the latter
override the former).
map1 - the fist hashmap to mergemap2 - the second hashmap to merge
public static java.lang.String mapToString(java.util.Map map)
