Source Link

Document

Creates a new, empty map with an initial table size based on the given number of elements ( initialCapacity ), initial table density ( loadFactor ), and number of concurrently updating threads ( concurrencyLevel ).

Usage

From source file:ConcurrentHashSet.java

/**
 * Constructs a new, empty set; the backing <tt>ConcurrentHashMap</tt> instance has the
 * specified initial capacity and the specified load factor.
 * //from w w  w  .  ja  v a2s .co  m
 * @param initialCapacity
 *            the initial capacity of the hash map.
 * @param loadFactor
 *            the load factor of the hash map.
 * @throws IllegalArgumentException
 *             if the initial capacity is less than zero, or if the load factor is nonpositive.
