Java Map interface is not a subtype of the Collection interface. The Java platform contains three general-purpose Map implementations: HashMap, TreeMap, and LinkedHashMap. Why do we need a HashMap? A HashMap however, store items in &#34; key \/ value &#34; pairs, and you can access them by an index of another type (e.g. a String ). HashMap and LinkedHashMap allow null keys and values, but TreeMap doesn&#39;t allow any null key or value.<\/strong><\/p>\n<p><figure> \t\t<img decoding=\"async\" src=\"https:\/\/i.pinimg.com\/736x\/56\/07\/1c\/56071c8f5cdad24191bfebab08d6e9af--java-tourist-map.jpg\" alt=\"Tourist map of West Java | Tourist map, Java, Map\" style=\"width: 100%; padding: 5px; background-color: grey;\"><figcaption>Tourist map of West Java | Tourist map, Java, Map (Lenora Riley)<\/figcaption><\/figure>\n<p> \t \t<strong>What Map In Java<\/strong>. <strong>Each key maps to a value hence the name.
