```
public SHMap(int initialCapacity,
             float loadFactor)
```
    Constructs an empty HashMap with the specified initial capacity and load factor.
    
    参数:
    
    initialCapacity - the initial capacity
    
    loadFactor - the load factor
    
    抛出:
    
    java.lang.IllegalArgumentException - if the initial capacity is negative or the load factor is nonpositive
  - SHMap
```
public SHMap(int initialCapacity)
```
    Constructs an empty HashMap with the specified initial capacity and the default load factor (0.75).
    
    参数:
    
    initialCapacity - the initial capacity.
    
    抛出:
    
    java.lang.IllegalArgumentException - if the initial capacity is negative.
  - SHMap
```
public SHMap()
```
    Constructs an empty HashMap with the default initial capacity (16) and the default load factor (0.75).
  - SHMap
```
public SHMap(java.util.Map<? extends K,? extends V> m)
```
    Constructs a new HashMap with the same mappings as the specified Map. The HashMap is created with default load factor (0.75) and an initial capacity sufficient to hold the mappings in the specified Map.
    
    参数:
    
    m - the map whose mappings are to be placed in this map
    
    抛出:
    
    java.lang.NullPointerException - if the specified map is null
- 方法详细资料
  - size
```
public int size()
```
    Returns the number of key-value mappings in this map.
    
    指定者:
    
    size 在接口中 java.util.Map<K,V>
    
    覆盖:
    
    size 在类中 AbstractMap<K,V>
    
    返回:
    
    the number of key-value mappings in this map
  - isEmpty
```
public boolean isEmpty()
```
    Returns true if this map contains no key-value mappings.
    
    指定者:
    
    isEmpty 在接口中 java.util.Map<K,V>
    
    覆盖:
    
    isEmpty 在类中 AbstractMap<K,V>
    
    返回:
    
    true if this map contains no key-value mappings
  - get
```
public V get(java.lang.Object key)
```
    Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.
    More formally, if this map contains a mapping from a key k to a value v such that (key==null ? k==null : key.equals(k)), then this method returns v; otherwise it returns null. (There can be at most one such mapping.)
    A return value of null does not necessarily indicate that the map contains no mapping for the key; it's also possible that the map explicitly maps the key to null. The containsKey operation may be used to distinguish these two cases.
    
    指定者:
    
    get 在接口中 java.util.Map<K,V>
    
    覆盖:

  - put
```
public V put(K key,
             V value)
```
    Associates the specified value with the specified key in this map. If the map previously contained a mapping for the key, the old value is replaced.
    
    指定者:
    
    put 在接口中 java.util.Map<K,V>
    
    覆盖:

    value - value to be associated with the specified key
    
    返回:
    
    the previous value associated with key, or null if there was no mapping for key. (A null return can also indicate that the map previously associated null with key.)
  - putAll
```
public void putAll(java.util.Map<? extends K,? extends V> m)
```
    Copies all of the mappings from the specified map to this map. These mappings will replace any mappings that this map had for any of the keys currently in the specified map.
    
    指定者:

public V remove(java.lang.Object key)
```
    Removes the mapping for the specified key from this map if present.
    
    指定者:
    
    remove 在接口中 java.util.Map<K,V>
    
    覆盖:
    
    remove 在类中 AbstractMap<K,V>
    
    参数:
    
    key - key whose mapping is to be removed from the map
    
    返回:
    
    the previous value associated with key, or null if there was no mapping for key. (A null return can also indicate that the map previously associated null with key.)
  - clear
```
public void clear()
```
    Removes all of the mappings from this map. The map will be empty after this call returns.
    
    指定者:
    
    clear 在接口中 java.util.Map<K,V>
    
    覆盖:
    
    clear 在类中 AbstractMap<K,V>
  - containsValue
```
public boolean containsValue(java.lang.Object value)
```
    Returns true if this map maps one or more keys to the specified value.
    
    指定者:
    
    containsValue 在接口中 java.util.Map<K,V>
    
    覆盖:
    
    containsValue 在类中 AbstractMap<K,V>
    
    参数:
    
    value - value whose presence in this map is to be tested
    
    返回:
    
    true if this map maps one or more keys to the specified value
  - clone
```
public java.lang.Object clone()
```
    Returns a shallow copy of this HashMap instance: the keys and values themselves are not cloned.
    
    返回:
    
    a shallow copy of this map
  - keySet
```
public java.util.Set<K> keySet()
```
    Returns a Set view of the keys contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations.
    
    指定者:
    
    keySet 在接口中 java.util.Map<K,V>
    
    覆盖:

    返回:
    
    Set
  - values
```
public java.util.Collection<V> values()
```
    Returns a Collection view of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa. If the map is modified while an iteration over the collection is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The collection supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Collection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.
    
    指定者:
    
    values 在接口中 java.util.Map<K,V>
    
    覆盖:
    
    values 在类中 AbstractMap<K,V>
  - entrySet
```
public java.util.Set<java.util.Map.Entry<K,V>> entrySet()
```
    Returns a Set view of the mappings contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation, or through the setValue operation on a map entry returned by the iterator) the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.
    
    指定者:
    
    entrySet 在接口中 java.util.Map<K,V>
    
    指定者:
    
    entrySet 在类中 AbstractMap<K,V>
    
    返回:
    
    a set view of the mappings contained in this map
