Let's implement the first method, the put method, as follows:
put(key, value) { if (key != null && value != null) { const position = this.hashCode(key); if (this.table[position] == null) { // {1} this.table[position] = new LinkedList(); // {2} } this.table[position].push(new ValuePair(key, value)); // {3} return true; } return false;}
In this method, we will verify whether the position we are trying to add the value to already has other values in it ({1}). If this is the first time we are adding an element in this position, we will initialize it with an instance of the LinkedList class ({2} - which we learned in Chapter 6, Linked Lists). Then, we will add the ValuePair instance to the LinkedList instance using the push method ...
