public IntHashMap ( Map t ) { this ( Math . max ( 2 * t . size ( ) , 11 ) , 0.75f ) ; putAll ( t ) ; }
constructs a new map with the same mappings as the given map . the map is created with a capacity of twice the number of mappings in the given map or 11 ( whichever is greater ) , and a default load factor , which is 0 . 75 .
