In java implement the following methods shown by the pseudocode for a hashtable:

HashRemainder(int key) { return key % N }

HashMidSquare(int key) { squaredKey = key * key extractedBits = squaredKey >> LowBitsToRemove extractedBits = extractedBits & (0xFFFFFFFF >> (32-R)) return extractedBits % N }

HashMutliplicative(string key) { stringHash = InitialValue for (each character strChar in key) { stringHash = (stringHash * HashMultiplier) + strChar } return stringHash % N }
