- Method Detail
  - newHashMapWithExpectedSize
```
public static <K,V> HashMap<K,V> newHashMapWithExpectedSize(int expectedSize)
```
    Creates a HashMap instance, with a high enough "initial capacity" that it should hold expectedSize elements without growth. This behavior cannot be broadly guaranteed, but it is observed to be true for OpenJDK 1.6. It also can't be guaranteed that the method isn't inadvertently oversizing the returned map.
    
    Parameters:
    
    expectedSize - the number of elements you expect to add to the returned map
    
    Returns:
    
    a new, empty HashMap with enough capacity to hold expectedSize elements without resizing
    
    Throws:
    
    IllegalArgumentException - if expectedSize is negative
  - immutableEntry
```
public static <K,V> Map.Entry<K,V> immutableEntry(K key,
                                                              V value)
```
    Returns an immutable map entry with the specified key and value. The Map.Entry.setValue(V) operation throws an UnsupportedOperationException.
    
    The returned entry is serializable.
    
    Parameters:
    
    key - the key to be associated with the returned entry
    
    value - the value to be associated with the returned entry
