put	back to summary
public V put(K key, V value) Overrides java.util.HashMap.put. Implements java.util.Map.put. Doc from java.util.Map.put. Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value. (A map `m` is said to contain a mapping for a key `k` if and only if `m.containsKey(k)` would return `true`.) Parameters key:K key with which the specified value is to be associated value:V value to be associated with the specified key Returns:V 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`, if the implementation supports `null` values.) Annotations @Override

public V put(K key, V value)

Overrides java.util.HashMap.put.

Implements java.util.Map.put.

Doc from java.util.Map.put.

Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value. (A map m is said to contain a mapping for a key k if and only if m.containsKey(k) would return true.)

Parameters

key:K: key with which the specified value is to be associated
value:V: value to be associated with the specified key

Returns:V

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, if the implementation supports null values.)

putAll	back to summary
public void putAll(Map<? extends K, ? extends V> m) Overrides java.util.HashMap.putAll. Implements java.util.Map.putAll. Doc from java.util.Map.putAll. Copies all of the mappings from the specified map to this map (optional operation). The effect of this call is equivalent to that of calling `put(k, v)` on this map once for each mapping from key `k` to value `v` in the specified map. The behavior of this operation is undefined if the specified map is modified while the operation is in progress. If the specified map has a defined encounter order, processing of its mappings generally occurs in that order. Parameters m:Map<? extends K, ? extends V> mappings to be stored in this map Annotations @Override

public void putAll(Map<? extends K, ? extends V> m)

Overrides java.util.HashMap.putAll.

Implements java.util.Map.putAll.

Doc from java.util.Map.putAll.

Copies all of the mappings from the specified map to this map (optional operation). The effect of this call is equivalent to that of calling put(k, v) on this map once for each mapping from key k to value v in the specified map. The behavior of this operation is undefined if the specified map is modified while the operation is in progress. If the specified map has a defined encounter order, processing of its mappings generally occurs in that order.

Parameters

m:Map<? extends K, ? extends V>: mappings to be stored in this map

remove	back to summary
public V remove(Object key) Overrides java.util.HashMap.remove. Implements java.util.Map.remove. Doc from java.util.Map.remove. Removes the mapping for a key from this map if it is present (optional operation). More formally, if this map contains a mapping from key `k` to value `v` such that `Objects.equals(key, k)`, that mapping is removed. (The map can contain at most one such mapping.) Returns the value to which this map previously associated the key, or `null` if the map contained no mapping for the key. If this map permits null values, then a return value of `null` does not necessarily indicate that the map contained no mapping for the key; it's also possible that the map explicitly mapped the key to `null`. The map will not contain a mapping for the specified key once the call returns. Parameters key:Object key whose mapping is to be removed from the map Returns:V the previous value associated with `key`, or `null` if there was no mapping for `key`. Annotations @Override

public V remove(Object key)

Overrides java.util.HashMap.remove.

Implements java.util.Map.remove.

Doc from java.util.Map.remove.

Removes the mapping for a key from this map if it is present (optional operation). More formally, if this map contains a mapping from key k to value v such that Objects.equals(key, k), that mapping is removed. (The map can contain at most one such mapping.)

Returns the value to which this map previously associated the key, or null if the map contained no mapping for the key.

If this map permits null values, then a return value of null does not necessarily indicate that the map contained no mapping for the key; it's also possible that the map explicitly mapped the key to null.

The map will not contain a mapping for the specified key once the call returns.

Parameters

key:Object: key whose mapping is to be removed from the map

Returns:V

the previous value associated with key, or null if there was no mapping for key.
