There are several that implement java map but the three main and general Latvia Phone Number List purpose implementations are hash map, tree map and linked hash map. Let’s look at the features of each implementation and the behavior of the example hash map class the most common class that implements the java map interface is hash map. This is an implementation of a map interface based on a hash table. It implements all map operations and allows zero values Latvia Phone Number List ​​and one zero key. In addition, this class does not support any order between its elements. Object that associates keys with values ​​and is designed Latvia Phone Number List for faster searching. Data is stored in pairs of keys and values, and each key is unique. Each key associates a value, and hence a name map. These key value pairs are called map records. Inside, java. The map contains this method for inserting, removing and retrieving keystrokes for elements. With such methods, it is a great tool to use for linking keys and values ​​ There can be no duplicate keys in the map , and each Latvia Phone Number List key can be assigned a maximum of one value. Some installations allow zero key and zero value but some do not ( tree map).The map interface does not guarantee the order of the links, but it depends on the implementation. For example, hash map does not guarantee mapping order, but Latvia Phone Number List tree map does. The abstract map class contains the java map interface and the framework implementation of most of the map concrete elements in the class to extend.
