Did you know?
NettetExample: A HashMap initialized with default settings has a capacity of 16 and a load factor of 0.75f. Capacity * load factor = 16 * 0.75 = 12. So adding the 13th item to the HashMap will cause it to grow to (approximately) 32 buckets. Invalid example: A HashMap initialized with a capacity of 16 and a load factor of 0.0f.
