Modifier and Type	Method	Description
`static int`	`calcCapacity(int size)`	Calculates initial capacity needed to hold `size` elements in a HashMap or Hashtable without forcing an expensive increase in internal capacity.
`static String`	`mapToString(Map map)`	spit out each name/value pair
`static HashMap`	`merge(Map map1, Map map2)`	Creates a new `HashMap` that has all of the elements of `map1` and `map2` (on key collision, the latter override the former).

protected HashMapUtils()
```
- Method Detail
  - calcCapacity
```
public static final int calcCapacity(int size)
```
    Calculates initial capacity needed to hold 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));
    
    Parameters:
    
    size - the number of items that will be put into a HashMap
    
    Returns:
    
    initial capacity needed
  - merge
```
public static HashMap merge(Map map1,
                            Map map2)
```
    Creates a new HashMap that has all of the elements of map1 and map2 (on key collision, the latter override the former).
    
    Parameters:
    
    map1 - the fist hashmap to merge
    
    map2 - the second hashmap to merge
    
    Returns:
    
    new hashmap
  - mapToString
```
public static String mapToString(Map map)
```
    spit out each name/value pair
