BasicHashMap

Hash map with linked lists to handle collisions, created as an exercise.

Generic types are supported.

Built using Java hashCode and java.util.LinkedList.

Usage

Instantiate

BasicHashMap<String, Integer> map = new BasicHashMap<String, Integer>();

Store a key.

String name = "Michael";
Integer age = 22;
map.add(name, age);

Get a key.

Integer age = map.get("Michael"); // 20

Remove a key.

map.remove("Michael");

Update a value.

map.add("Bill",22);
map.update("Bill", 45);
Integer value = hash.get("Bill") //45

Initialize a map with a custom array size.

// This is a map of size 1, so all elements
// will be in the linked list at index 0.
HashMap miniMap = new HashMap(1);
