question: void resize ( int newCapacity ) { Entry [ ] oldTable = table ; int oldCapacity = oldTable . length ; if ( oldCapacity == MAXIMUM_CAPACITY ) { threshold = Integer . MAX_VALUE ; return ; } Entry [ ] newTable = new Entry [ newCapacity ] ; transfer ( newTable ) ; table = newTable ; threshold = ( int ) ( newCapacity * loadFactor ) ; }
target:  Rehashes the contents of this map into a new array with a larger capacity. This method is called automatically when the number of keys in this map reaches its threshold. If current capacity is MAXIMUM_CAPACITY, this method does not resize the map, but sets threshold to Integer.MAX_VALUE. This has the effect of preventing future calls.
