      public WeakValueHashMap(int initialCapacity, float loadFactor)
      Constructs a new, empty WeakValueHashMap with the given initial capacity and the given load factor.
      Parameters:
      initialCapacity - The initial capacity of the WeakValueHashMap
      loadFactor - The load factor of the WeakValueHashMap
      Throws:
      IllegalArgumentException - If the initial capacity is less than zero, or if the load factor is nonpositive

    • WeakValueHashMap

      public WeakValueHashMap(int initialCapacity)
      Constructs a new, empty WeakValueHashMap with the given initial capacity and the default load factor, which is 0.75.
      Parameters:
      initialCapacity - The initial capacity of the WeakValueHashMap
      Throws:
      IllegalArgumentException - If the initial capacity is less than zero

    • WeakValueHashMap

      public WeakValueHashMap()
      Constructs a new, empty WeakValueHashMap with the default initial capacity and the default load factor, which is 0.75.

    • WeakValueHashMap

      public WeakValueHashMap(Map<K,V> t)
      Constructs a new WeakValueHashMap with the same mappings as the specified Map. The WeakValueHashMap is created with an initial capacity of twice the number of mappings in the specified map or 11 (whichever is greater), and a default load factor, which is 0.75.
      Parameters:
      t - the map whose mappings are to be placed in this map.
