Constructor Summary
`IntToIntHashMap()` Initializes a map with a capacity of 8 and a load factor of 0,25.
`IntToIntHashMap(int capacity)` Initializes a map with the given capacity and a load factor of 0,25.
`IntToIntHashMap(int capacity, double factor)` Constructs a new map with initial capacity, and load factor.

Method Summary

Constructor Detail

### IntToIntHashMap

    public IntToIntHashMap()

  Initializes a map with a capacity of 8 and a load factor of 0,25.

### IntToIntHashMap

    public IntToIntHashMap(int capacity)

  Initializes a map with the given capacity and a load factor of 0,25.

Parameters:
  `capacity` - the initial capacity.

### IntToIntHashMap

    public IntToIntHashMap(int capacity,
                           double factor)

  Constructs a new map with initial capacity, and load factor.

  The capacity is the number of keys that can be mapped without resizing the arrays in which keys and values are stored. For efficiency, only a fraction of the elements in those arrays are used. That fraction is the specified load factor. The initial length of the arrays equals the smallest power of two not less than the ratio capacity/factor. The capacity of the map is increased, as necessary. The maximum number of keys that can be mapped is 2^30.

Parameters:
  `capacity` - the initial capacity.
  `factor` - the load factor.

Method Detail

### setDefaultValue

    public void setDefaultValue(int defaultValue)

  Set the value to be returned to indicate an unused entry

### clear

    public void clear()

  Clears the map.

### find

    public boolean find(int key)

  Finds a key in the map.

  Parameters:
    `key` - Key
  Returns:
    true if the key is mapped

### get

    public int get(int key)

  Gets the value for this key.

  Parameters:
    `key` - Key
  Returns:
    the value, null if not found.

### size

    public int size()

  Gets the size of the map.

  Returns:
    the size

### remove

    public boolean remove(int key)

  Removes a key from the map.

  Parameters:
    `key` - Key to remove
  Returns:
    true if the value was removed

### put

    public void put(int key,
                    int value)

  Adds a key-value pair to the map.

  Parameters:
    `key` - Key
    `value` - Value
