	LinkedHashMap(Map m) Constructs an insertion-ordered LinkedHashMap instance with the same mappings as the specified map.
	LinkedHashMap(int initialCapacity, float loadFactor, boolean accessOrder) Constructs an empty LinkedHashMap instance with the specified initial capacity, load factor and ordering mode.
	LinkedHashMap(int initialCapacity, float loadFactor) Constructs an empty insertion-ordered LinkedHashMap instance with the specified initial capacity and load factor.

Method

void	clear()
Object	clone() Creates and returns a copy of this object.
V	computeIfAbsent(K key, Function mappingFunction) If the specified key is not already associated with a value (or is mapped to null ), attempts to compute its value using the given mapping function and enters it into this map unless null .
boolean	containsKey(Object key) Returns true if this map contains a mapping for the specified key.
boolean	containsValue(Object value) Returns true if this map maps one or more keys to the specified value.
Set>	entrySet() Returns a Set view of the mappings contained in this map.
boolean	equals(Object o) Compares the specified object with this map for equality.
void	forEach(BiConsumer action)
V	get(Object key) Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.
Class	getClass() Returns the runtime class of this Object .
V	getOrDefault(Object key, V defaultValue)
int	hashCode() Returns the hash code value for this map.
boolean	isEmpty() Returns true if this map contains no key-value mappings.
Set	keySet() Returns a Set view of the keys contained in this map.
V	put(K key, V value) Associates the specified value with the specified key in this map (optional operation).
void	putAll(Map m) Copies all of the mappings from the specified map to this map (optional operation).
V	putIfAbsent(K key, V value) If the specified key is not already associated with a value (or is mapped to null ) associates it with the given value and returns null , else returns the current value.
V	remove(Object key) Removes the mapping for a key from this map if it is present (optional operation).
int	size() Returns the number of key-value mappings in this map.
String	toString() Returns a string representation of the object.
Collection	values() Returns a Collection view of the values contained in this map.
